Abstract
Abstract. The enhancement of light absorption and photoluminescence quenching properties
of the bulk heterojunction systems which were fabricated using poly(N-vinylcarbazole) (PVK);
poly(N-hexylthiophene) (P3HT) and fullerene derivative 1-(3-methoxycarbonyl) propyl-1-phenyl-
[6,6] C61 (PCBM) were investigated. The optimized material showed a broad absorption in the
region from ultra violet to near infra-red and the photoluminescence quenching higher than 90%.
The obtained results provide further insight into photophysics of the heterojunction system and
device performance improvement by using this system as an active layer.
