Abstract
The following review paper contains the basic principle behind working of the solar cell. The present day PSC are made of electron donating (conjugated polymer) and electron accepting molecules(usually fullerene and its derivatives). The concept of the bulk heterojunction has resulted into great improvement in the efficiency of the PSC. In order to control the morphology and to improve the efficiency of the PSC processes like thermal annealing, solvent annealing and choice different solvents are being adopted by researchers. The reasearch carried out by Yang and D Chirvase are described in this paper.Downloads
