Flexographic Printing – High Throughput Technology for Fine Line Seed Layer Printing on Silicon Solar Cells
Presented at the 28th European PV Solar Energy Conference and Exhibition, 30 September – 04 October 2013, Paris, France FLEXOGRAPHIC PRINTING – HIGH THROUGHPUT TECHNOLOGY FOR FINE LINE SEED LAYER PRINTING ON SILICON SOLAR CELLS Andreas Lorenz1, Andre Kalio1, Gunter Tobias Hofmeister1, Sebastian Nold1, Lorenz Friedrich1, Achim Kraft1, Jonas Bartsch1, Dietmar Wolf2, Martin Dreher2, Florian Clement1, Daniel Biro1 1Fraunhofer Institute for Solar Energy Systems ISE, Heidenhofstr. 2, 79110 Freiburg, Germany 2Deutschsprachiges Flexodruck-Technologiezentrum DFTA-TZ, Nobelstraße 10, 70569 Stuttgart, Germany Phone: +49 761 4588 5299, email: [email protected] ABSTRACT: Within this work, seed layer grids for solar cell front side metallization were applied using flexographic printing which represents an innovative, high-throughput approach for solar cell front side metallization. Fine line seed layer contact grids with a silver consumption lower than 10 mg per cell could be realized on alkaline textured Czochralski-grown silicon wafers with an edge length of 156 mm. Subsequently, the seed layer has been reinforced with silver using light induced plating (LIP). In order to determine the optimum LIP process, three groups were plated with different amounts of silver deposition. The results were analyzed before and after plating regarding silver consumption, contact finger geometry and interruptions. Solar cell parameters were determined after plating. It was demonstrated, that a homogeneous front side seed layer metallization without interruptions down to a line width of 25 µm can be realized using flexographic printing. The best cell reached a conversion efficiency of 18 % after silver LIP which is comparable to standard screen printed cells on the used Si wafer material. -

Called “xylographic printing,” it was used before Gutenberg for illustrations, playing cards, and small documents. Moveable type allowed corrections and editing. A wood engraving uses the end grain, where a wood cut uses the plank grain. Polymer plates are made from digital files which drive special engraving machines to produce relief plates. These plates are popular with many of today’s letterpress printers who produce invitations, and collectible prints. Metal relief cylinders were used to print repetitive designs, such as those on wrap - ping paper and wall paper. In the 1930s, the invention of cellophane led to the development of the anilox roller and flexographic printing. Today, flexography prints most of the flexible packaging film which accounts for about half of all packaged products. Hobbyists, artists, and printmakers cut away non-printing areas on sheets of linoleum to create relief surfaces. Wood cut Wood engraving and Metal plate Relief cylinder Flexographic plate Linoleum cut Foundry type began with Gutenberg and evolved through Jenson, Garamond, Moveable type Caslon and many others. Garamond was the first printer to cast type that was sold to other printers. By the 1880s there were almost 80 foundries in the U.S. One newspaper could keep one foundry in business. Machine typesetting changed the status quo and the Linotype had an almost immediate effect on type foundries. Twenty-three foundries formed American Type Founders in 1890. -

A Context and Taxonomy for Printing: Intersections of Culture and Technology, 1850-2000
A context and taxonomy for printing: Intersections of culture and technology, 1850-2000 This project is based upon a research funding application being made to the UK Arts and Humanities Research Council (AHRC), the body responsible in the UK for funding University research in this area. It has been written by myself, Stephen Hoskins and Paul Thirkell in response to a series of discussions at the last AEPM General Meeting in Odense, Denmark and in particular response to Alan Marshall’s paper at that meeting. Unfortunately there have been problems in submitting this application, partly because of the pressures of daily life, which fall upon us all, but primarily because of the (AHRC) body closing its application process for 12 months and the ongoing funding crisis in UK universities. However the AHRC is now open to fresh bids, if there are still enough museums interested Research Context: As observed by Alan Marshall in 2008,1 ‘in the 1960s, before the extraordinary eruption of digital techniques in the graphic arts, no one, not even the best informed commentator could have imagined the desktop publishing and digital prepress techniques which we take for granted…’ Forty years later, we are in a position to put the apparently unique phenomenon of the digital revolution into its broader technological, historical and social perspective. However, there has been little analysis of the technical developments, social impacts, and market shifts that led up to the present domination of digital printing. The printing museum offers an entirely appropriate forum for understanding the core events that have culminated in the digital revolution. -
Other Printing Methods
FLEXO vs. OTHER PRINTING METHODS Web: www.luminite.com Phone: 888-545-2270 As the printing industry moves forward into 2020 and beyond, let’s take a fresh look at the technology available, how flexo has changed to meet consumer demand, and how 5 other popular printing methods compare. CONTENTS ● A History of Flexo Printing ● How Flexo Printing Works ● How Litho Printing Works ● How Digital Printing Works ● How Gravure Printing Works ● How Offset Printing Works ● What is Screen Printing? ● Corrugated Printing Considerations ● Flexo Hybrid Presses ● Ready to Get Started with Flexo? 2 A History of Flexo Printing The basic process of flexography dates back to the late 19th century. It was not nearly as refined, precise, or versatile as the flexo process today -- and can be best described as a high-tech method of rubber stamping. Printing capabilities were limited to very basic materials and designs, with other printing methods greatly outshining flexo. Over the past few decades flexo technology has continuously evolved. This is largely thanks to the integration of Direct Laser Engraving technology, advancements in image carrier materials, and in press technologies. These innovations, among others, have led to increased quality and precision in flexo products. These technological improvements have positioned flexography at the helm of consumer product and flexible packaging printing. Flexo is growing in popularity in a variety of other industries, too, including medical and pharmaceutical; school, home, and office products; and even publishing. How Flexo Printing Works Flexo typically utilizes an elastomer or polymer image carrier such as sleeves, cylinders, and plates. The image carrier is engraved or imaged to create the design for the final desired product. -
Printing Industry Is the Large Proportion of Very Small Firms
The printing sector is a diversified industry sector composed of firms who perform printing as well as firms who render services for the printing trade, such as platemaking and bookbinding. One of the most significant characteristics of the printing industry is the large proportion of very small firms. The Census Bureau reported that in 2002 nearly half of the 37,538 printing companies had fewer than five employees; approximately 80 percent employed fewer than 20 workers. Processes used in printing include a variety of methods used to transfer an image from a plate, screen, film, or computer file to some medium, such as paper, plastics, metal, textile articles, or wood. The most prominent of these methods is to transfer the image from a plate or screen to the medium (lithographic, gravure, screen, and flexographic printing). A rapidly growing new technology uses a computer file to directly "drive" the printing mechanism to create the image and new electrostatic and other types of equipment (digital or nonimpact printing). Four Main Segments The printing industry can be separated into four main segments: Lithography Flexography Gravure Screen printing Lithography Lithography is a planographic printing system where the image and non-image areas are chemically differentiated with the image area being oil receptive and non-image area water receptive. Ink film from the lithographic plate is transferred to an intermediary surface called a blanket, which, in turn, transfers the ink film to the substrate. Fountain solution is applied to maintain the hydrophilic properties of the non-image area. Ink drying is divided into heatset and non- heatset. -
I. INTRODUCTION and BACKGROUND the Printing Industry Is One of the Largest Manufacturing Industries in the United States
I. INTRODUCTION AND BACKGROUND The printing industry is one of the largest manufacturing industries in the United States. The industry is dominated by small and medium-sized businesses, most of them with fewer than 20 employees. In 2002, according to the Bureau of Census, approximately 83 percent of the screen printing industry was comprised of small businesses. The Info USA Power Business Database estimates the number of screen printers in 2002 in the U.S. at 16,341. California has 1,886 screen printing establishments. Volatile Organic Compound (VOC) emissions from solvent cleaning operations contribute significantly to the South Coast Air Basin’s emission inventory. The South Coast Air Quality Management District (SCAQMD or District) periodically adopts an Air Quality Management Plan (AQMP). This AQMP calls for significant reductions in VOC emissions from cleaning and degreasing operations by 2010 to achieve attainment status. The SCAQMD regulates VOC emissions from businesses located in the four county area including Los Angeles County, Orange County, San Bernardino County and Riverside County. One of the SCAQMD rules, Rule 1171 “Solvent Cleaning Operations,” regulates the VOC content of screen printing cleanup solvents. The VOC content of screen printing cleanup solvents is currently set at 500 grams per liter. The District plans to reduce the allowed VOC content to 100 grams per liter on July 1, 2006. Lowering the VOC content to 100 grams per liter would reduce emissions of these solvents by about 1.3 tons per day. By July 1, 2006, screen printers in southern California must convert to alternative low-VOC cleanup materials. -

Printing Press Operations
Property Risk Consulting Guidelines PRC.17.18.1 A Publication of AXA XL Risk Consulting PRINTING PRESS OPERATIONS INTRODUCTION Printing has progressed from the Gutenberg press, which required three minutes per impression, to today’s multicolor, two-sided, continuous presses that operate well in excess of 2000 ft/min (610 m/min). There are four major printing processes: lithography, letterpress, gravure and silk-screening. A lithography offset press prints from a level or plane surface; a letterpress prints from a raised surface; a gravure press prints from a depressed or sunken surface; and silk-screening prints by pushing ink through fabric. From the 6th Annual Report to the Congress of the United States: Printing Industry report, Figure 1 shows 1994 industry market share. PROCESSES AND HAZARDS The hazards of printing presses include the transfer and use of flammable inks; solvent recovery and pollution control devices; hydraulic and lubrication oil systems; gas or oil-fired dryers; electrostatic buildup from high press speeds; paper dust; and paper storage near presses. This section discusses common printing processes and their hazards. Loss prevention and control guidelines address construction features, flammable and combustible liquids handling, protection of the press area, electrical features, drying, and the disposal of solvent vapors. 50 47 45 40 35 30 28 25 19 20 Percent (%) Percent 15 10 5 3 3 0 Lithographic Letterpress Gravure Silk-screen Other Figure 1.
