   Amorphous silicon carbide (a-SiC) is an excellent passivation layer material for silicon solar cells and a substitution of amorphous silicon in various applications. Thin layers of a-SiC have also been used as optical windows in the construction of tandem solar cells, and located on top of the crystalline silicon substrate they are promising alternatives to conventional homojunction PV cells. This paper summarizes the research activities carried out on thin a-SiC films and reviews the obtained results focused mainly on electrical characterization.
