Effects of PCBM concentration on the electrical properties of the Au/P3HT:PCBM/n-Si (MPS) Schottky barrier diodes
2:1, 6:1 and 10:1 P3HT:PCBM mass ratios used Au/P3HT:PCBM/n-Si SBDs were fabricated. IV characteristics of SBDs were investigated for different P3HT:PCBM mass ratios. Electrical parameters of SBDs can be controlled by PCBM concentration in P3HT:PCBM. Increasing the PCBM concentration improves the performance of Au/P3HT:PCBM/n-Si SBD.
