Organic photovoltaic (OPVs) have possibility for fabricating low-cost and ubiquitous renewable energy in the next generation due to their abundant resources and environmentally friendly carbon-based materials. Besides, their flexibility, low-weight, and transparency provide highly accessibility to our life. However, toxic processing solvent, not enough performance, short lifetime, and small device size were still things to improve. In this session, our efforts to improve OPVs performances by developing acceptor materials were presented. We synthesized new small molecular acceptor materials and optical, thermal, and electrochemical properties were examined. Acceptor materials were fabricated to binary single cell OPVs with proper donor materials and its photovoltaic properties were investigated.
