Research status of large-area flexible organic solar cells

Abstract

Solar cell technology, as the hottest clean energy technology nowadays, can convert the abundant solar energy on earth into electricity. As the latest development direction of solar cell technology, large-area F-OSCs have a broad application prospect. Compared with traditional inorganic solar cells, large-area flexible organic solar cells(F-OSCs) have various advantages including flexibility, low cost and low weight. Because of its unparalleled advantages, the research field of large-area F-OSCs has achieved rapid development in recent years. This review shows representative results in the field through different aspects of the structure, fabrication process and applications of large-area F-OSCs. Also this review summarizes the problems that still exist in various aspects of large-area F-OSCs. Nowadays, the main problems that need to be solved for large-area F-OSCs are 1) increasing the power conversion efficiency(PCE) of the cells 2) improving the stability of the devices in the natural environment and 3) reducing the cost of manufacturing. Finally, an outlook on the future widespread application of large-area F-OSCs is presented.
