Amorphous Silicon Thin Film Solar Cells Although the technology of manufacturing amorphous silicon (a-Si) thin-film solar cells has been well developed for more than three decades, the large-area a-Si thin-film solar cells with high efficiency can be implemented only recently by the improvement of the large-scale coating and deposition technologies. In fact, the microstructure of the a-Si solar cell is very simple as a consequence of the nature of photovoltaic mechanism. The schematic diagram of the structure is illustrated in Fig. 1. Upon the glass substrate, the functionality of power generation can be achieved through the front electrode (TCO layer), the p-i-n active layer, and the back contact as a back electrode of the cell. The rough surfaces of both TCO layer and back contact can enhance light absorption via the light trapping effect after sunlight is incident into the solar cell from the glass side. |

Amorphous Silicon/Microcrystalline Silicon Thin Film Solar Cells The efficiency of thin-film silicon solar cells can be increased by the deposition of the second active layer with microcrystalline silicon ( |
