Abstract
The project aims to manufacture the above for the development of low-cost high-efficiency practical cells. Technologies were developed to homogeneously fabricate films with an average efficiency of 10% or more in a 100mm times 85mm area in a STAR (naturally surface texture and enhanced absorption with a back reflector) structure thin-film polycrystalline silicon (poly-Si) solar cell. The texture shape was improved for a higher light trapping effect and a STAR structure cell highly sensitive to long wavelengths and fit for use for a hybrid cell bottom layer was obtained. Various cells were examined for temperature characteristics, and it was found that thin-film poly-Si cells present a temperature coefficient equal to or less than that of bulk single-crystal silicon systems, and hybrid cells a temperature coefficient similar to that of a-Si systems. The technology was applied to a hybrid solar cell in which an a-Si cell was placed on STAR structure thin film poly-Si cells, and a resultant 3-layer a-Si/poly-Si/poly-Si cell exhibited a stabilization factor of 12.0% after 550 hours of optical irradiation.
