Various Materials and Structures for Heterojunction Organic Solar Cells Design for Efficiency Enhancement

The hazards of prevailing global warming on this planet have forced human beings to utilize clean energy substitutes. None of the clean energy sources could be better than the Sun. To exploit solar energy to the maximum extent, solar cells were invented. However, the solar cells ruling today’s world are all made from inorganic materials which are not only expensive but also involve complex fabrication processes. Additionally, these cells are limited to utilization on rooftops only. To overcome this scenario organic solar cells are the reliable contender to inorganic solar cells. A review of the origin and developments regarding organic solar cells is explained in this paper, and the improvement in the efficiency of a suggested organic solar cell with optimization at 800[Formula: see text]nm is 24.05%.
