Photoconduction in CuO

Abstract With the global surge in the research on perovskite halides as cost effective alternative Silicon solar cells, it is necessary to find the replacement of very expensive hole transport materials (HTM). Copper oxide (CuO) is one of the inorganic binary compound and much cheaper than the organic HTMs. In this work, light absorption behaviour and photoconductivity of CuO are examined. The band gap and Urbach energy is estimated using UV-visible absorbance spectrum. The photo-conduction study of the CuO is carried in 1.5AM-G solar light.
