Abstract
We have studied the thin films of P3HT:PCBM and P3HT:ITIC blends as a prospective active layer for Organic Solar Cells by absorption, photoluminescence, and short-circuit current density–voltage characteristics. The potential estimation of structural changes in such photovoltaic devices is shown by employing the variations in absorption and photoluminescence spectra. The comparative analysis of key features of the absorption and photoluminescence spectra can be used as an indicator of their structural and photophysical properties.
