An efficient enhancement in organic photovoltaics by introducing simple-structured benzo[1,2-b:4,5-b′]dithiophene-based large-bandgap small molecules as the third component

Abstract

Ternary strategy has been widely demonstrated as an efficient and facile method to improve the performance of organic photovoltaics (OPVs). Besides commonly used relatively complex molecules or copolymers, developing cost-effective...

Suppression of Undesired Losses in Organometal Halide Perovskite‐Based Photoanodes for Efficient Photoelectrochemical Water Splitting

“…[ 5,6 ] The main limitation to achieving high solar‐to‐hydrogen conversion efficiency in unassisted solar water splitting is the relatively low‐efficiency of photoanodes compared with that of photocathodes. [ 7–9 ] Thus far, various materials have been investigated as candidates for photoanodes, including WO 3 , [ 10,11 ] Fe 2 O 3 , [ 12–14 ] BiVO 4 , [ 15–18 ] Ta 3 N 5 , [ 19–21 ] and Si. [ 22,23 ] However, these photoanodes still exhibit unsatisfactory efficiencies for PEC water oxidation.…”
