The determination of molecular conformations oligomeric acceptors (OAs) and their impact on packing are crucial for understanding the photovoltaic performance resulting polymer solar cells (PSCs) but have not been well studied yet. Herein, we synthesized two dimeric acceptor materials, DIBP3F-Se DIBP3F-S, which bridged segments Y6-derivatives by selenophene thiophene, respectively. Theoretical simulation experimental 1D 2D NMR spectroscopic studies prove that both dimers exhibit O-shaped...
Silicon/organic heterojunction solar cells (HSCs) based on conjugated polymers, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), and n-type silicon (n-Si) have attracted wide attention due to their potential advantages of high efficiency low cost. However, the state-of-the-art efficiencies are still far from satisfactory inferior junction quality. Here, facile treatments were applied by pretreating n-Si wafer in tetramethylammonium hydroxide (TMAH) solution using a...
Molecular doping has become a valuable technique for enhancing the efficiency of high-performance organic photovoltaic systems (OPVs). However, number known dopant molecules, especially n-type ones, that enhance PCE OPVs remains limited.
