Abstract

Carbon nanotubes exhibit remarkable optical transparency, low sheet resistance, and excellent mobility, making them highly sought after as transparent electrodes in future solar cells particularly organic solar cells. P-type doped carbon nanotubes with molybdenum trioxide (MoO3) facilitates efficient hole transport and good alignment of energy levels. The efficient functioning of Non-Fullerene ITIC-OE Acceptor organic solar cells with a transparent electrode fabricated from carbon nanotubes doped molybdenum trioxide (MoO3) has been investigated in this work. Optimized Voc of 0.9539 V, Jsc of 35.32 mA/cm2, PCE of 24.94% and Fill Factor (FF) of 74.02% are obtained by changing the band gap of MoO3 doped CNTs. Additionally, adding SnO2, TiO2, and ZnO as an Electron transport Layer (ETL) of the simulated cell produces an optimal outcome with TiO2, which has PCE of 25.71%. Carbon nanotubes shows external quantum efficiency up to 90% over a wide range of wavelength. According to these findings, transparent conductive electrodes based on carbon nanotubes will eventually be able to enhance the device performance of organic solar cells.
