SPECTRAL DEPENDENT ELECTRICAL CHARACTERISTICS OF THIN FILM A-SI:H SOLAR CELLS

Abstract

The iIluminatedcurrentMvoltage characteristics oflbin film a-Si:H
p-i-n solar cells were measured for the visible and near infrared spectral regions. The fill factor, the conversion efficiency, the open circuit voltage and the sbort circuit current were compared to the parameters of crystalline silicon pn-junction solar cells. The effect of irradiance and spectral illumination on the cell performance was investigated. FinaJJy, the applicability of the investigated thin film a-Si:H solar cells for its practical operation in Ethiopia is discussed.
