Scientists reveal factors for morphology control in organic solar cells

An international research team has fabricated organic solar cells using non-toxic solvents. The researchers identified interactions between the acceptor material side chains and the solvent, along with interactions between donor and acceptor materials, as key factors for controlling morphology in organic solar cells. Scientists led by Sweden's Linköping University have developed organic solar cells using various environmentally friendly solvents to identify key factors influencing the cells' morphology. The scientists said that morphology optimization has been crucial in achieving power conversion ...
