Abstract
Heterojunctions have been fabricated between CdSe films made by vacuum evaporation and amorphous hydrogenated Si films deposited by plasma d ischarge. With adjusted conditions, junctions of good rectification ra tios have been produced (1000:1 at 2 V), although showing significant interface states. The band offsets were determined by an internal phot oemission technique as 0.06 eV for the valence bands and 0.02 eV for t he conduction bands. A small unoptimised solar cell gave near 7% effic iency.
