20.2% Efficiency Organic Photovoltaics Employing a π‐Extension Quinoxaline‐Based Acceptor with Ordered Arrangement

20.2% Efficiency Organic Photovoltaics Employing a π‐Extension Quinoxaline‐Based Acceptor with Ordered Arrangement Organic solar cells, as a cutting-edge sustainable renewable energy technology, possess a myriad of potential applications, while the bottleneck problem of less than 20% efficiency limits the further development. Simultaneously achieving an ordered molecular arrangement, appropriate crystalline domain size, and reduced nonradiative recombination poses a significant challenge and is...
