Abstract

Extremely Thin Absorber (ETA) solar cells were made using chemical-bath-deposited Sb2S3 as the absorber and TiO2/CuSCN as the interpenetrating electron/hole conductors. A solar conversion efficiency of 3.37% at 1 sun illumination was obtained. Surface oxidation of the Sb2S3 formed a passivation layer on Sb2S3: without this oxidation, much poorer cells were obtained. Preliminary stability measurements showed good stability over 3 days of illumination (at 60 mW/cm2) under load.
