| Bioactivity | PTB7-Th is a classic organic photovoltaic (OPV) cell donor polymer that can be added as a dielectric to increase the short-circuit current and fill factor of polymer solar cells, improving the photovoltaic efficiency of the device[1]. |
| Invitro | PTB7-Th can be doped as a third substance to prepare polymer solar cells. The effect of PTB7-Th on the device performance can be investigated by changing the concentration of PTB7-Th. The short-circuit current and the fill factor of the polymer solar cell were both improved by doping PTB7-Th, which led to the improvement of the device photoelectric conversion efficiency. It has also been shown that the addition of PTB7-Th can broaden the absorption spectrum of the active layer and increase the number of photons absorbed by the active layer, which is beneficial to the enhancement of short-circuit current[1]. |
