Unravelling the impact of thiophene auxiliary in new porphyrin sensitizers for high solar energy conversion

Here, we reported two new D-π-A Porphyrin sensitizers for dye-sensitized solar cells (DSSC) and catalytic hydrogen production under visible light. The results indicate that the modulation of auxiliary acceptors remarkably influenced the rate, 2691, 6641 and 7396 μmol g-1 h-1 hydrogen evolution performance for LG-5, LG-tT and LG-DtT respectively. New sensitizers, LG-tT and LG-DtT are making it possible to achieve a high power conversion efficiency of (PCE) of 8.25 % and 7.05 %.
