Initial results of CdS/CuInTe2 heterojunction formed by flash evaporation

Abstract The CuInTe 2 thin films is one of the most attractive semiconductors for solar cells applications, since its direct band gap energy ( E g≈1 eV) is suitable as an absorber in photovoltaic conversion. In this letter the CuInTe 2 thin films are prepared by flash evaporation technique. X-ray diffraction measurements on the as-deposited CuInTe 2 film showed that these films consist mainly of the chalcopyrite phase. The junction formation in the n-CdS/p-CuInTe 2 cell has been investigated using current–voltage ( I – V ) and capacitance-voltage ( C – V ) measurements.
