Progress towards practical organic solar cells amenable to large scale production is reported. Fullerene-free organic solar cells with a PCE of ∼4.8% are achieved based upon an active layer composed of the standard donor polymer PTB7-Th and a highly soluble twisted PDI acceptor tPDI-Hex. All devices can be fabricated and tested in air with 'as-cast' active layers being processed from the greener solvents o-xylene (or trimethyl benzene) or the eco-friendly and bio-derived solvent 2Me-THF without loss in efficiency.
据报道，在适用于大规模生产的实用有机太阳能电池方面取得了进展。基于由标准供体聚合物PTB7-Th和高可溶性扭曲的PDI受体tPDI-Hex组成的活性层，实现了具有约4.8%的功率转换效率（PCE）的无富勒烯有机太阳能电池。所有器件都可以在空气中制造和测试，“浇铸后”的活性层由更环保的溶剂邻二甲苯（或三甲苯）或生态友好型且源自生物的溶剂2Me-THF加工而成，而效率不会降低。
