Summary

Solar energy has primary importance among all renewable energy resources. Photovoltaic devices allow for the most simple and efficient conversion of the solar energy to electricity. This chapter focuses on the organic semiconductor nanomaterials used for construction of efficient bulk heterojunction solar cells. Research efforts focus mainly on achieving higher power conversion efficiencies in the devices by using novel materials and their combinations while the stability issue remains non-addressed in the vast majority of publications. Since the power conversion efficiency depends linearly on short-circuit current, open-circuit voltage and fill factor, each of these parameters should be increased. Importance of the active layer nanomorphology of organic solar cells was first recognized in 2001 for the solar cells based on the MDMO-PPV/PCBM composite. New materials and new knowledge brought up commercially interesting certified solar cell efficiencies of 8-10% reported recently by several independent groups.
