Abstract
The performance of bulk-heterojunction solar cells made with
poly(3-hexylthiophene) (P3HT) as the donor and phenyl-C61-butyric acid
methyl ester (PCBM) as the acceptor depends strongly on various factors
in fabrication processes. This work studies the effect of the thickness
of the P3HT:PCBM layer produced in the spin coating process on
photovoltaic performances. Thickness dependent optical absorption in
P3HT:PCBM layer is numerically modelled and the results are compared
with experimental data. In addition, it is analyzed how degradation of
air-exposed P3HT:PCBM blends depends on the storage time in nitrogen
atmosphere.
