Organic and polymeric photovoltaic (PV) cells show promise as low-cost, light weight, flexible, and renewable energy sources and have been extensively investigated during the past decade. Low band gap polymer materials and their application in organic photovoltaics (OPV) are reviewed. We detail the synthetic approaches to low band gap polymer materials starting from the early methodologies polythiazole structures to the current state of the art that relies on alternating copolymer of donor and acceptor groups where strategies for band gap design are possible. Current challenges for OPV such as chemical stability and energy level alignment are discussed. We synthesized polythiazole derivative and the structure and photovoltaic properties of polymer was characterized using H-NMR, C-NMR, GPC, TGA, DSC, UV-visible spectroscopy. |
