Paper Abstract

In this work, we present the evolution of optical constants varying with distinct annealing temperature for poly (3- hexylthiophene) (P3HT) and 6,6-phenyl C61-butyric acid methyl ester (PCBM). With calculation of the transmission and reflection spectra in P3HT:PCBM photovoltaic device , the optical properties correlation to annealing temperature is studied. The solar cell power conversion efficiency and optical absorption is compared simultaneously. Finally, the electric field amplitude in the device is discussed for detailed explanation of thermal annealing effects on the organic photovoltaic device performance.
