Silicon Heterojunction and Thin-Film Photovoltaic Device Engineering
This community develops silicon-based solar cells and related thin-film semiconductor structures to convert sunlight into electricity, focusing on material interfaces, surface passivation, and device architecture.
The work centers on crystalline and amorphous silicon, with significant attention to heterojunction interfaces, porous silicon, and silicon nanowires. Key materials include gallium arsenide, germanium, and various oxides such as silicon nitride and molybdenum oxide. Methods involve chemical etching, vapor deposition, and laser patterning to create passivating contacts and optimize surface properties. Applications span rigid photovoltaic modules, flexible solar cells, and tandem solar structures, with a strong emphasis on improving efficiency through precise control of electrical and optical properties at the material level.
The largest share of this community’s output is found in silicon research, accounting for 26.4% of all silicon research, and 27,866 papers here. Germanium follows with 18.5% of its research, and gallium with 7.0%.
The community comprises 81,427 papers, publishing primarily in the Journal of Applied Physics, Applied Physics Letters, and MRS Proceedings.
Recent work includes silicon solar cells with hybrid back contacts, high-efficiency silicon heterojunction cells, and the impact of solar radiation on photovoltaic panel material properties.
