The efficiency of Solar cells has been impacted by various factors. Being an abundant source by nature, research work is being carried upon regarding their performance parameters to a great extent. In this paper solar structure is optimized for better performance. The simulation of the proposed solar cell is carried on SCAPs software. The simulation work portraits the effect incorporating front and back contacts in the existing perovskite solar cell structure. The involvement of contact parameters in the structure resulted in efficiency improvement. Withal substituting the (Ca) metal as Back contact with work function of 2.9 eV and (Au) as front contact with work function 5.47 eV, the solar cell showed quantitative improvement from existing designs. In the study, existing perovskite solar cells with ETL Cd1- xZnxS(Cadmium zinc sulphide), perovskite layer MAPbI3- xClx, and HTL CuI(Copper Iodide) and CuSbS2 (Copper antimony sulfide) is compared in terms of efficiency. The proposed solar cell with Spiro-OMeTAD as HTL showed the highest PCE of 28.06%. |
