Bulk heterojunction (BHJ)-type polymer solar cells (PSCs) have been extensively employed in binary composite films consisting of p-type donors and n-type acceptors as active layers. Many studies have been conducted on conventional BHJ PSCs fabricated using polymer donors and fullerene derivatives or nonfullerene small molecules or polymer acceptors. Additionally, much effort is being expended to develop a single-component active layer in PSCs rather than a binary blend active layer. This can be accomplished by the development of materials that include both donors and acceptors, which will promote light absorption, exciton dissociation, and charge transport. In this presentation, polymer solar cells with active layers bearing heterogeneous and homogenesous materials and their performances will be demonstrated. |
