Since surface color impact on solar radiation absorption and it may affect other chemical process relating to energy possession. So UV prone region how dye synthesized solar cell will be affected by it.
If it expose in the sun then naturally UV is there. I think, the molecular volume related donor-acceptor binding energy and excitonic carrier dissociation are linked thermalization energy (high in UV). Its relationship with carrier transport properties is potential. The molecular based materials minimum mobility or carrier transport results in low conduction of heat or huge dissipation.
