Abstract:

In the last centuries, human beings have sought to supply their energy. Energy from fossil fuels is recognized as a sources unrenewable energy. Recently, due to the reduction of unrenewable resources, increased greenhouse gas emissions and environmental pollution, and endangering human health, people beings are forced to replace non-renewable energy sources with renewable energy sources. The most important devices to convert solar energy into electrical energy are solar cells. Organic solar cells are a green class of solar cells. Although organic photovoltaic solar cells (OPVSCs) have lower returns than the first generation solar cells; but, due to low cost of fabrication, lightweight and good flexibility, have attracted a lot of attentions. In green OPVSCs construction, from small and large organic molecules based on donorـlinkersـacceptor have been used.

Keywords: solar energy, organic solar cell, cyano acceptor groups, green solar cell.
