Abstract
A trial to improve the conversion efficiency of amorphous silicon (a-Si) solar cells was carried out utilizing the optical confinement effect for low energy photons near the optical band edge. For this purpose a TiO2/Ag/SUS (where SUS represents high grade mirror etched stainless steel) highly reflective semitextured substrate acting as a light scatterer was developed. Inverted-type a-Si solar cells fabricated on this substrate exhibit a remarkable increase in the carrier collection efficiency in the spectral region just above the optical energy gap of a-Si. The increase in J(sc) was about 20 percent compared with that of a cell on a conventional SUS substrate. Using this substrate, a conversion efficiency of more than 9 percent was attained. 16 references.
