TL;DR: In this paper, a trifluoromethylation strategy was introduced to overcome this drawback and to boost the perovskite solar cells' solar to electric power conversion efficiency (PCE).
Journal ArticleDOI
A structurally simple perylene dye with ethynylbenzothiadiazole-benzoic acid as the electron acceptor achieves an over 10% power conversion efficiency
TL;DR: In this paper, a structurally simple donor-acceptor (D-A) perylene dye C272 was synthesized without the use of any coadsorbate, achieving an impressive power conversion efficiency of 10.4% at air mass global (AM1.5G) conditions.
Journal ArticleDOI
Improving the performance of dye-sensitized solar cells with electron-donor and electron-acceptor characteristic of planar electronic skeletons
TL;DR: In this paper, the transformation of the electron-acceptor from twisting 4-(benzo[c][1,2,5]thiadiazol-4-yl)benzoic acid (BTBA) to planar 4-((7-ethynylbenzo [c][ 1, 2, 5]thieno-4]-hexyl)ethylbenzo (EBTEBA) can significantly stabilize the lowest unoccupied molecular orbital (LUMO) energy level of an organic dye but does not lower EQEs.
