✦ Synopsis

Amorphous silicon-selenium solar cells, where a selenium alloy thin film was used as an intrinsic layer, were successfully fabricated by plasma-enhanced chemical vapor deposition. The cells have a simple p-i-n structure. The maximum conversion efficiency of the ceils was 5.1%, measured under 100 mW/cm [2] ELH white light illumination. The fabricated selenium alloy solar cells exhibited stable characteristics under white light soaking, with respect to those of amorphous silicon comparison solar cells, fabricated under similar conditions. Measurement of the quantum efficiency showed that this cell can be used as a top cell in a tandem cell structure.
