We have studied the chalcopyrite compound ZnGeAs2 to access its potential as a novel photovoltaic material. Thin films of ZnGeAs2 have been produced by pulsed laser depositionThe films are deposited at 315 °C and are amorphous. They crystallize above 450 °C and improve in crystallinity up to and including 600 °C. At that temperature the Hall mobility is 55 ± 2 cm2√Vs , which is within uncertainty to the highest mobility ever reported for this material. We find a rather high carrier concentration, of order 1018 - 1019 for the annealed films, presumably due to the presence of Zn vacancies. The material is an effective light absorber, with an absorption coefficient of order 104 1/cm at 1.2 eV. These properties suggest ZnGeAs2 may be used to produce cost effective and efficient solar cells.
