CdS/CdTe thin film photovoltaics were produced with transition metal nitrides (TMNs) as back contacts. The devices show photovoltaic activity but a significant Schottky barrier was found at the back contact. Solar cells perform better as the ZrN films are thicker due to improved microstructure. The good reflectance of ZrN makes it acts as a reflective layer to reduce optical losses and lower the thickness...
