文摘
- •
TPA dyes with different number of anchors were studied for co-sensitized solar cells.
- •
The high efficiency achieved with a ratio of 1:1:5 (TPA3T3A: TPA3T1A: TPA3T2A).
- •
Charge recombination suppressed and e− lifetime prolonged with this cosensitizer.
- •
Light harvesting and diffusion length also improved with this cosensitizer.
