Abstract :
An ultralight flexible a-Si solar cell fabricated on a transparent film substrate has been developed. High photoconductivity (σph) of 2×10-5 Ω-1 cm-1 and high photosensitivity (σph/σd) of 1×106 were obtained with a-Si films deposited by H2-dilution of SiH4 on a transparent film substrate at 180°C. Prebaking the transparent film substrate effectively reduced the impurity content of the a-Si film. A maximum output power of 550 mW and a power-to-weight ratio of 275 mW/g were obtained for an integrated-type a-Si solar cell with a size of 110×115 mm. As the first application of this flexible a-Si solar cell, a solar-powered airplane has been developed, and it completed a transcontinental flight across the United States
