摘要
The semitransparent flexible organic solar cell takes advantages of flexibility,transparency,color adjust ment property,which is more conducive to integrate on buidings and mobile terminals.Ascribing to the developments of narrow band gap donors and the new non-fullerene acceptors,the power conversion efficiency of semitransparent flexible organic solar cells has been achieved 10% to 12% with average visible transmittance of 17% to 21%.This review summarizes the molecular design of the most representative layer materials,and discusses the characterization of semitransparent parameters paradigms,then we discuss how to optimize the device in combination with optical simulation,and finally list the recent development of semitransparent flexible electrodes of ITO-free organic solar cells,and give our perspectives on the next step direction.
