  • Abstract Polymer solar cells made from poly(2,6-bis(3-dodecylthiophen-2-yl)-N-alkyl-dithieno[3,2-b:2′,3′-d]pyrrole) (PDTPBT) with different side chain lengths as donors and [6,6]-phenyl C61-butyric acid methyl ester (PCBM) as the acceptor were investigated. After optimization with thermal treatments, the device made from PDTPBT with a longer alkyl side chain (P1) delivers a power conversion efficiency (PCE) of 1.06%, which is much higher than that made from PDTPBT with a shorter side chain (0… CONTINUE READING
