Abstract:
The conventional Spiro OMeTAD/Au hole collector in perovskite solar cells is replaced by low-cost CuInS2/Carbon hole collector. In addition to decreasing the cost, the complexity of the deposition of Au using a vacuum-based physical evaporation system is also removed. The carbon electrode can be deposited using doctor blading and printing methods. Decreasing the interfacial resistances and decreasing recombination are needed for improving the efficiency of this structure. Herein interfacial engineering at the interface of CuInS2 and perovskite light absorbent is done using poly methyl methacrylate. The filling factor and efficiency of perovskite solar cell with this structure are improved from 0.64 to 0.71 and 14.37% to 15.99% respectively.
