Abstract
Application of solar cell technology is considered for fabrication of silicon-based light-emitting diodes, which are especially interesting as optoelectronic devices compatible with the conventional silicon technology. First experimental results obtained with non-optimized amorphous silicon-crystalline silicon heterostructure demonstrate an external quantum efficiency of 0.013% (the internal quantum efficiency being 0.3%). The measures directed to a further development of such light-emitting diodes are discussed. They indicate a possibility to increase the quantum efficiency up to several percent.
