Abstract

Amorphous Diamondlike Carbon (a:DLC) films are suitable materials to be used as a protective layer and anti-reflecting coating for silicon solar cells. Microhardness tests show high hardness of about 4700kg/mm2. Optical measurements, in the visible light, on silicon solar cell without anti-reflecting (AR) coating on which a:DLC was deposited as anti-reflecting coating show a significant reduction in reflection of the light of about 25 ÷ 45% as compared to the reflection from the solar cell before the deposition of the a:DLC film. The I-V characteristic of solar cells without anti-reflecting coating and with a:DLC as AR coating layer show an improvement in the short circuit current (from 107mA to 116mA) and in the efficiency of the cell by 1% (from 8% to 9%).
