Modeling of organic photovoltaic (OPV) cells can be achieved by adaptation of
Replacement of traditional crystalline solid state materials
by organic materials leads to much lower carrier
mobility and to a new carrier, the exciton, which is a bound
electron-hole pair. The Buxton-Clarke model
includes electrons, holes, and excitons, together with generation,
dissociation, and recombination mechanisms connecting these carriers,
partially induced by device illumination. Device materials
consist of a polymer:fullerene blend, poly(3-hexylthiophene):
6,6-phenyl C61-butyric acid methyl ester (P3HT:PCBM).
In this article, the model is used to simulate an active layer of 20 nm;
results include I-V curves and carrier current densities.
