Photovoltaics cell and module Producers The battle for supremacy

Market leader has already demonstrated: thin-film While the manufacturers of solar cells and crystalline modules are modules as mass product – it can be done. Photo: First Solar already following a clear path in the direction of mass production, the thin-film producers have to deal with dropping silicon prices and the lower levels of efficiency. CI(G)S technology could soon become a serious competition for the successful CdTe modules.

Experts predict that position ten by ­SolarWorld (3.9 %).

116 Sun & Wind Energy 10/2010 manufaCturEr Continuous demand on the market of HigHpowEr Solar cells will continue to see an unbroken demand in the future. Estimations are that the global solar cell modulES production will reach a capacity of about 10.5 MW in the current year. In 2011, the total capacity could ar­ rive at between 13 and 14 GW. In order to be well-­ positioned along all the stages of the value-added chain, the industry participants are focusing on in­ creasing their vertical integration and the further processing of their solar cells into modules. “Trina Solar and Yingli are very successful with this strategy. But it doesn’t always have to work out that well”, says de Haan. In a rapidly growing and changing market, defending market shares along the value-added chain requires not only massive investments but also continuous quality improvement on all stages. It therefore takes a lot of money and expertise. Companies continuing their core competencies in the cell manufacturing segment are therefore increas­ ingly focusing on mass production and contract mod­ Energy Systems for the future ule manufacturing. One example is Flextronics ­International Ldt. Starting at the end of the year, the www.galaxy-energy.com company will supply modules for the US cell specialist SunPower Corp. from its plant in California. The Asia- based company will also function as module supplier to Q-Cells – with a capacity of 200 MW in its facility in the Malaysian port of Tanjung Pelepas. In the opinion of iSuppli, the cooperation between these two players and others announced can be read as early signs of a new trend. “I believe these moves are part of an emerging trend in the solar market that closely paral­ lels the situation in the electronics market in the ear­ ly 1990s,” says Greg Sheppard, Chief Research Offic­ The brand er for iSuppli. “Faced with the rapidly exploding de­ mand, the need to manufacture products close to end markets and the requirement to obtain sufficient cap­ ital, electronic Original Equipment Manufacturers in for quality the early 1990s turned to Electronics Manufacturing Services (EMS) companies such as Flextronics for help. This led to a massive boom in electronics out­ sourcing and explosive growth in the EMS business. At the beginning of 2010, a new EMS boom has been performance starting up, this time in the business.”

Other than in the case of solar cells, the brand man­ agement is an important factor for the module indus­ try, says Lohr. Another key aspect is the lowering of production costs. Together with other analysts, Lohr expects that the market will consolidate in the fore­ seeable future and then be in the hands of a small group of major companies. The top 10 list for the module manufacturing in­ dustry reveals the size to which the players dominat­ ing the market have meanwhile grown. In most cases, the production capacity is more than a purely theoret­ ical size: presently, the capacity exploitation achieved by the leading producers of crystalline modules ar­ rives at about 90 %. However, after a demand peak during the last two years, the manufacturers are now faced with an over­ supply situation. In the long-term, the differences in demand and supply will eventually level off, expects Markus Lohr. In the last months, for example, the strong demand on the German market has already helped to compensate the oversupply. According to iSuppli, the currently largest player for the first quar­ ter of 2010 is Suntech with a market penetration of 9.9 %, followed by Sharp (7.4 %), Trina Solar (6.8 %), and Yingli (each with 6.7 %), ­SolarWorld and SunPower (each with 5.4 %), Solarfun (4.7 %), Sanyo Electric (4.5 %) and Ningbo Solar ­Electric (3.6 %). What the distribution of the market shares will look like in 2011 partly also depends on the develop­ ment of the silicon market and the strength of the US dollar. With exception of Germany-based Wacker Chemie AG, the raw material silicon is usually traded SolarWorld cells: a blue in US dollars.

system below 100 kW. For such a system, the module costs had ranged at € 3 per kW. It was generally as­ sumed that € 2.50 per kW for a thin-film module would be a competitive price. Meanwhile, the price for a crystalline system has dropped to between € 2,500 and 3,000 per kW”, says Dr. Hartmut Gross, Sales Manager Thin Film at Centrotherm ­Photovoltaics AG. On the spot market, the price for a First Solar cad­ mium telluride (CdTe) module presently ranges at around 1.60 €/kW. Some Chinese manufacturers achieve the same for monocrystalline modules. These modules are usually more expensive, but the spot market currently makes an over-average amount of brands available in the lower price segment. “In my opinion, this is due to the fact that First Solar has been registering a huge demand while the situation for some of the China-based crystalline module man­ ufacturers looks quite different “, says Dirk Morbitzer of Renewable Analytics. Type of technology a decisive factor

Thin film does not have an easy stand in the present market development. However, the situation varies considerably for the different types of thin-film tech­ nology meaning that one must take a closer look. In view of the relatively low efficiencies, the situation is worst for amorphous silicon modules. Generally, ex­ perts are doubtful of the technology’s potential.

122 Sun & Wind Energy 10/2010 Many even believe that the low efficiencies could make amorphous modules obsolete. Even the tan­ dem cell segment has felt the blow. Although these modules provide a favourable temperature coeffi­ cient and handle diffused light well, the efficiencies are still considered to be insufficient. “Tandem junc­ tion panels are in a slightly better position than amorphous modules. But their average conversion efficiency also barely outreaches 8 %. In the course of the next two years, these modules will have to achieve at least 10 % to be competitive”, says de Haan. So far, the industry has had a hard time fulfilling the efficiency requirement. Especially, companies of small or medium size often depend on major equip­ ment suppliers meaning their ability to react to the market development is rather limited and processes are usually slower. Therefore, the decision of ­US-based Applied Materials to drop its Sunfab solar line “could be a signal”, believes Lohr. Similarly, Schott Solar AG, which has similar experience in sili­ con thin film also focuses on crystalline technologies in view of an expansion of its capacities. Finally, even Japan-based Sharp, which has been active in the ­area of silicon thin-film for many years as well, has so far been expanding its capacities by only 160 MW. ­Originally, the company had announced 480 MW by 2010. Q-Cells seems to be changing its strategy, too. Ex­ cept for the CIS subsidiary Solibro GmbH, which will

The company has supplied its first turnkey fabs to a customer based in Taiwan who has already started producing mod­ ules in the 30 MW plant. “I expect that facilities will be in a position to produce more than 500 MW CIS thin-film modules by the end of 2011”, says ­Centrotherm expert Gross.
