Optimizing the performance of TiO2/P3HT hybrid solar cell by effective interfacial modification

â¿¢Employing an organic triphenylamine dye as heterojunction interfacial modifier.â¿¢The use of modifier facilitates the compatibility between TiO2 and P3HT.â¿¢Interfacial modification promotes exciton dissociation, reduces charge recombination.â¿¢Voc and Jsc enhanced obviously, that improved photovoltaic performance to 2.01%.
