Abstract

We fabricated highly stable a-Si:H solar cell using low band gap intrinsic layer fabricated by RP-CVD. We obtained a-Si:H with optical band gap of less than 1.65 eV with deposition rate of 0.18 $\AA$/sec, and used this material as bottom i-layer of a-Si:H double stacked solar cells. We have succeeded in the fabrication of very stable a-Si:H double stacked solar cell of which the conversion efficiency is about 9% and the degradation is less than 4% after light illumination for 100h under 350mW/cm$^{2}$.
