Annealing of Silicon Heterojunction Solar Cells: Interplay of Solar Cell and Indium Tin Oxide Properties

Christophe Ballif, Raphaël François Lemerle, Mathieu Gérard Boccard, Jan Haschke, Brahim Aissa

In this paper, we report the evolution of silicon heterojunction solar cell properties focusing, in particular, on the indium tin oxide (ITO) layers upon consecutive thermal annealing. We find that the charge carrier density

Impact of the Oxygen Flow during the Magnetron Sputtering Deposition on the Indium Tin Oxide thin films for Silicon Heterojunction Solar Cell

Christophe Ballif, Mathieu Gérard Boccard, Jan Haschke, Jean Cattin, Brahim Aissa, Akshath Raghu Shetty

We report on the optoelectronic properties of ITO layers deposited by DC sputtering, using different oxygen to total flow ratios [r(O-2) = O-2/Ar, ranging from 1% to 8%], for silicon heterojunction (SHJ) solar cell application. The depth profiling of the v ...

Contact Resistivity of the p-Type Amorphous Silicon Hole Contact in Silicon Heterojunction Solar Cells

Mathieu Gérard Boccard

In silicon heterojunction solar cells made with high-lifetime wafers, resistive losses in the contacts dominate the total electrical power loss. Moreover, it is widely believed that the hole contact stack—a-Si:H(i)/a-Si:H(p)/ITO/Ag—is responsible for more ...

Paths for maximal light incoupling and excellent electrical performances in silicon heterojunction solar cells

Christophe Ballif, Bertrand Yves Paul Paviet-Salomon, Laurie-Lou Senaud, Matthieu Despeisse, Mathieu Gérard Boccard, Monica Morales Masis, Jan Haschke, Luca Massimiliano Antognini, Jean Cattin, Oscar Esteban Rucavado Leandro, Raphaël Monnard, Julie Amandine Dreon, Vincent Philippe Paratte, Olivier Denis Dupré, Angela Nicole Fioretti, Sihua Zhong

We discuss here optical losses in silicon heterojunction solar cells and strategies to minimize them. Optical losses originate from most non-crystalline-silicon layers involved in the solar cell. A breakdown for typical values is shown evidencing that supp ...

Appraisement of Crystal Expansion in CH3NH3PbI3 on Doping: Improved Photovoltaic Properties

Mohammad Khaja Nazeeruddin

Three-dimensional hybrid perovskite materials (CH3NH3PbI3) suffer from intrinsic instability owing to organic cation evaporation and ion migration. The inclusion of a large organic cation such as guanidinium has been probed to stabilize the structure. This ...

Elucidating the role of the InGaN UL in the efficiency of InGaN based light-emitting diodes

Camille Haller

Blue III-nitride light-emitting diodes (LEDs) are widely used nowadays in solid-state lighting, as white light can be produced by combining yellow phosphors and blue LEDs. This technology has the advantage to have a higher luminous efficiency than incandes ...
