Incorporation of high band gap Carbon Nanotubes as Transparent Conductive Electrode in ITIC-OE accepter Organic solar cell

Abstract

The most common transparent conducting electrode, ITO, is delicate and prone to shattering under mechanical stress, which lowers the device's performance on flexible plastic substrates. Because of their exceptional optical transparency, low sheet resistance, and great mobility, carbon nanotubes have garnered a lot of interest as a Transparent Conductive electrode in organic solar cells. Molybdenum Trioxide (MoO3) doping of carbon nanotube Transparent Conductive electrodes makes p-doping, good energy-level alignment, and improved hole transport possible. In the present study, the performance of Non-Fullerene ITIC-OE Acceptor Organic Solar Cells with a transparent electrode fabricated from Carbon Nanotubes doped with Molybdenum trioxide (MoO3) is simulated using SCAPS 1-D. The optimized PCE of 24.94 %, Fill Factor (FF) of 74.02 %, Jsc of 35.32 mA/cm2 and Voc of 0.9539 V are shown in the current work by varying the band gap of MoO3 doped CNTs. Also, upgrading the simulated cell's Electron transport Layer (ETL) with SnO2, TiO2, and ZnO yields an optimized result with TiO2 ETL, having PCE of 25.71%, FF of 76.30%, Jsc of 35.32 mA/cm2, and Voc of 0.9539 V. These results demonstrated the possibilities for ITIC-OE acceptor Organic Solar Cells with Transparent Conductive Electrodes made of carbon nanotubes to advance device performance in the near future.
