Thin film solar cells are an increasingly important technology for photovoltaic energy conversion. For Si based thin films, it is necessary to increase absorption path in order to absorb as many photons as possible. In this paper, we show how one can use a 2 dimensional photonic structure to diffract light and significantly enhance light absorption. The 2D photonic structure consists of precise cylindrical...
Based on Crosslight APSYS, amorphous Si (aSi:H)/amorphous SiGe:H (a-SiGe:H)/microcrystalline (??c-Si) thin film triple junction solar cells are modeled. Basic physical quantities like band diagrams, optical absorption and generation are obtained. Quantum efficiency and l-V curves for individual junctions are presented for current matching analyses. The whole TJ cell I-V curves are also presented and...
