| dc.description.abstract | The dcpcndcncy o fthc performance of organic bulk heteroj uct ion (B HJ) so lar cell s on the nanomorphology of the photoactive blend can be co ntro lled by so lvent additi ves. In this work BI-IJ so lar cells ba sed on PDTS'ITz:PCBM (1:1) which processcd by us ing a host solvcnt di-chl orobc nzcnc and 2.5% (v/v) different solvent add iti ves such as iodobutane, iodoethane, di-iodometha ne. and iodomcthane were constructed. The effects of the aforementioned addit ives on the photovolta ic parametcrs of the so lar cells wcre in vcstigated. Deviccs processed in 2.5% (v/v) of iodobutanc cx hibited the hi ghest power convers ion e fTI cicncy (PCE) up to 2.02% as compared to the pri st ine PDTST f z:PCBM deviccs (without add itive) (0.39%). The UY-Yis absorption spectra of films showed the existence of red shift in th c prcsence of thcse addi tivcs res ulting from thc growth of enhanced local structure with d istinct, opt imized phase scpa ratcd morph ology. Bcsides, the introduction of P3HT donor into PDTSTTzlPCBM system forming a ternary bl end a lso showed improvcd cfficicncy (2.42%) following thc incrcascd sho rt ci rcu it current up to 11.08 mi\/cm' through improvcd photon harvesting.
