  "description" : "This project was aimed to develop a-Si solar cells with an improved efficiency and to determine the characteristics of these cells. Mainly cells with p-i-n-structure were deposited by decomposition of SiH/sub 4/ in a radio-frequency glow discharge. The main results are: SS/p-i-n/ITO cells having 5% AM-1 efficiency at an area of 16 cm/sup 2/; glass/SnO/sub 2//p-i-n/Al cells with areas < 1 cm/sup 2/ having AM-1 efficiencies up to 6%. The cell stability under prolonged illumination was found to depend on firstly the deposition conditions of the a-Si:H material and secondly on whether the light is entering through the p/sup +/- or n/sup +/ layer. Cells with an initial efficiency of 4.5% suffered a decrease of efficiency to 0.94 of its initial value after 400 hours of AM-1 illumination. The cells developed in this project possess properties sufficient to provide power for small-scale applications such as in pocket calculations. However, more progress is needed in efficiency, long-time stability and a-Si deposition rate before a-Si cells become economically useful for power applications.",
