design guideline of high efficiency crystalline si thin film solar cell with nanohole array textured surface
Journal of Applied Physics, 2011Co-Authors: Fei Wang, Shemein Wong, Hongyu Yu, Junshuai Li, Xincai Wang, H Y ZhengAbstract:Silicon thin film with a nanohole (NH) array textured surface is systematically studied via simulation for solar energy harvesting and compared with a nanopillar (NP) array textured one. It is found that for the same thickness and optimized structure parameters, the NH array shows superior light trapping capability and thus, higher power conversion efficiency than its NP counterpart. The requirement for efficient cells at the optically optimized NH and NP geometries are studied in terms of minority carrier diffusion length, Emitter doping level, and the Emitter Junction depth after considering the impact of surface recombination velocity. The results provide a practical guideline to design and fabricate high efficiency and cost effective NH textured Si thin film solar cells.

design high efficiency si nanopillar array textured thin film solar cell
IEEE Electron Device Letters, 2010Co-Authors: Shemein Wong, Gang Zhang, D L KwongAbstract:In this letter, the electrical performance in terms of power conversion efficiency (PCE) of Si nanopillar (SiNP)-textured thin-film solar cell is investigated via simulation, where the SiNP physical dimensions were predetermined for optimized solar-energy absorption. Several key factors affecting PCE of the solar cell, e.g., the impact of Si quality in terms of minority carrier lifetime, Emitter doping level, and Emitter Junction depth, is highlighted, and a practical guideline to design high-efficiency SiNP-textured thin-film solar cell is thus provided. The PCE of the structure under investigation can be significantly boosted, compared with the to-date reported Si thin-film solar cell.
