Summary:A series of unsymmetrical π-conjugated small molecules have been constructed from meso -alkyl substituted porphyrins as the central unit and 3-ethylrhodanine as the terminal group. Using PC 71 BM as an acceptor, and these small molecules as electron donors in solution-processed bulk-heterojunction solar cells, a high power conversion efficiency of 6.49% has been achieved. A series of new A-D-A structural 5,15-dialkylated porphyrin-cored small molecules have been developed as donors in bulk heterojunction organic solar cells, and the highest power conversion efficiency of 6.49% has been achieved.
