Summary A study on the use of CuO x , which is intended for replacing PEDOT:PSS as an anode interlayer in inverted hybrid solar cells, has been carried out. The fabricated solar cells have typical configuration structure of ITO/AZO/P3HT:PCBM/CuO x /Ag. AZO and CuO x thin layers were prepared by the sol gel method, while P3HT:PCBM layer was prepared by the spin‐coating method. The solar cell performances were found to be affected by the addition of CuO x interlayer. Solar cells with CuO x interlayer exhibit better working performance parameters (short‐circuited photocurrent density, filling factor and power conversion efficiency) in comparison to solar cells without using CuO x interlayer. These improvements are attributed to more efficient charge extraction due to reduction of trapping or recombination loss, which is in agreement with the observed photocurrent transient characteristics.
