Gluba, Steve Albrecht, Jörg Rappich, Lars Korte, Bernd Rech, and 4 Norbert H. Nickel 5 Helmholtz-Zentrum Berlin für Materialien und Energie GmbH, Institut für Silizium 6 Photovoltaik, Kekuléstr. 5, 12489 Berlin, Germany. 7 8 ABSTRACT: Perovskite solar cells with transparent contacts may be used to compensate 9 thermalization losses of silicon solar cells in tandem devices. This offers a way to outreach 10 stagnating efficiencies. However, perovskite top cells in tandem structures require contact layers 11 with high electrical conductivity and optimal transparency. We address this challenge by 12 implementing large area graphene grown by chemical vapor deposition as highly transparent 13 electrode in perovskite solar cells leading to identical charge collection efficiencies. Electrical 14 performance of solar cells with a graphene-based contact reached those of solar cells with 15 standard gold contacts. The optical transmission by far exceeds that of reference devices and 16 amounts to 64.3 % below the perovskite band gap. Finally, we demonstrate a four terminal 17 tandem device combining a high band gap graphene-contacted perovskite top solar cell 18 (Eg=1.6 eV) with an amorphous/crystalline silicon bottom solar cell (Eg=1.12 eV). 19 1 1 TOC GRAPHIC. 2 3 4 Hybrid perovskite methylammonium lead iodide (CH3NH3PbI3) attracts ever-growing interest 5 for use as a photovoltaic absorber.1 Only recently, Jeon et al. -

Comparison of Three Solar Cells Based on DSSC, Perovskite and Polymer Structures
Proceedings of the 2nd International Conference of Energy Harvesting, Storage, and Transfer (EHST'18) Niagara Falls, Canada – June 7 – 9, 2018 Paper No. 111 DOI: 10.11159/ehst18.111 Comparison of Three Solar Cells Based on DSSC, Perovskite and Polymer Structures Melika Dolatdoost, Farhad A. Boroumand Organic Electronics Laboratory, Electrical Engineering Faculty, K. N. Toosi University of Technology Seyed Khandan Bridge, Shariati Ave. Tehran, Iran [email protected]; [email protected] Extended Abstract In this work, we compare three solar cell structures that have been captured the attention of scientists as future technologies for green energy production. Dye synthesized solar cell was fabricated on FTO anode substrate using N719 dye active layer and platinum cathode based on Dr. Blade technique [1]. Perovskite solar cell was also made on uniform FTO on Glass as positive electrode. Mesoporous titania was deposited with Spin-Dip method and then, PbI2 was deposited and the whole sample placed in CH3NH3I and Spiro-OMeTAD was added to the solution. The structure was completed with depositing Gold as cathode of Perovskite cell [2]. For polymer based solar cell ITO on PET was considered as anode contact with MEH-PPV:ZnO nanocomposite polymer as active layer and Aluminum as negative electrode [3]. Perovskite structure had its own features such as high absorption coefficient, deep diffusion length of carriers and slow recombination speed. Also existence of Spiro-OMeTAD material reduced the recombination of charges, resulting in 2 highest efficiency of 8.7% among three devices and the utmost Isc of 19.98 mA/cm . Voc for this cell was acquired as 0.874V. -

Nanocrystal Quantum Dot Devices: How the Lead Sulfide (Pbs) System Teaches Us the Importance of Surfaces
398 CHIMIA 2021, 75, No. 5 COLLOIDAL NANOCRYSTALS doi:10.2533/chimia.2021.398 Chimia 75 (2021) 398–413 © W. Lin, M. Yarema*, M. Liu, E. Sargent, V. Wood Nanocrystal Quantum Dot Devices: How the Lead Sulfide (PbS) System Teaches Us the Importance of Surfaces Weyde M. M. Lina, Maksym Yarema*a, Mengxia Liub, Edward Sargentb, and Vanessa Wood*a Abstract: Semiconducting thin films made from nanocrystals hold potential as composite hybrid materials with new functionalities. With nanocrystal syntheses, composition can be controlled at the sub-nanometer level, and, by tuning size, shape, and surface termination of the nanocrystals as well as their packing, it is possible to select the electronic, phononic, and photonic properties of the resulting thin films. While the ability to tune the properties of a semiconductor from the atomistic- to macro-scale using solution-based techniques presents unique opportunities, it also introduces challenges for process control and reproducibility. In this review, we use the example of well-studied lead sulfide (PbS) nanocrystals and describe the key advances in nanocrystal synthesis and thin-film fabrication that have enabled improvement in performance of photovoltaic devices. While research moves forward with novel nanocrystal materials, it is important to consider what decades of work on PbS nanocrystals has taught us and how we can apply these learnings to realize the full potential of nanocrystal solids as highly flexible materials systems for functional semiconductor thin-film devices. One key lesson is the importance of controlling and manipulating surfaces. Keywords: Lead sulfide colloidal nanocrystals · Nanocrystal quantum dot devices · Semiconductor nanocrystals Weyde M. -

Perovskites-Based Solar Cells: a Review of Recent Progress, Materials and Processing Methods
materials Review Perovskites-Based Solar Cells: A Review of Recent Progress, Materials and Processing Methods Zhengqi Shi and Ahalapitiya H. Jayatissa * Nanotechnology and MEMS Laboratory, Department of Mechanical, Industrial and Manufacturing Engineering (MIME), University of Toledo, Toledo, OH 43606, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-419-530-8245 Received: 19 March 2018; Accepted: 2 May 2018; Published: 4 May 2018 Abstract: With the rapid increase of efficiency up to 22.1% during the past few years, hybrid organic-inorganic metal halide perovskite solar cells (PSCs) have become a research “hot spot” for many solar cell researchers. The perovskite materials show various advantages such as long carrier diffusion lengths, widely-tunable band gap with great light absorption potential. The low-cost fabrication techniques together with the high efficiency makes PSCs comparable with Si-based solar cells. But the drawbacks such as device instability, J-V hysteresis and lead toxicity reduce the further improvement and the future commercialization of PSCs. This review begins with the discussion of crystal and electronic structures of perovskite based on recent research findings. An evolution of PSCs is also analyzed with a greater detail of each component, device structures, major device fabrication methods and the performance of PSCs acquired by each method. The following part of this review is the discussion of major barriers on the pathway for the commercialization of PSCs. The effects of crystal structure, fabrication temperature, moisture, oxygen and UV towards the stability of PSCs are discussed. The stability of other components in the PSCs are also discussed.
