Enhancing the photovoltaic performance of triphenylamine based star-shaped molecules by tuning the moiety sequence of their arms in organic solar cells

Abstract

Better photovoltaic performance with the improvement of <italic>J</italic>_sc, <italic>V</italic>_oc and FF simultaneously was achieved by tuning the moiety sequence of their arms in star-shaped molecules, leading to the maximum PCE up to 5.07%.
