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.} }
