Optimization of Mass Ratio Effect on Active Layer of P3HT And PCBM With Electron Blocking Layer of PANI and PEDOT: PSS Solar Cell Characteristics

In this contribution we are reporting the mass ratio effect on the active layer of P3HT and PCBM with the electron blocking layer of PANI and PEDOT: PSS organic solar cells.The constructed solar cell system's performance has been evaluated under a light intensity of 1000W/m.This study used poly (3-hexylthiophene) (P3HT) and [6, 6]-phenyl-C61-butyric acid methyl esters (PCBM) as the active materials.P3HT serves as the donor, whereas PCBM functions as the acceptor.The ratios of PCBM to P3HT are 1:1, 1:2, and 2:1.P3HT: PCBM was combined using toluene solvents.Active layer of P3HT: PCBM of various mass ratios was performed while coating with different spin frequencies from 1000 to 2000rpm.PEDOT: PSS/PANI, the electron blocking layer (EBL), was created for 30 seconds at a constant speed of 2000 rpm.The thin film of PCBM: P3HT has been characterized using UV-Vi's spectroscopy and J-V characteristics under illumination.
