The fundamental understanding of light-matter interaction can provide to enhance the carrier generation and transport efficiency in photovoltaic materials. We will present a set of intriguing light-controlled spin polarized exciton, electron-hole pairs and free electron decay kinetics in spin impurity doped organic-inorganic  hybrid perovskites provides. We show that at cryogenic temperature, the spin impurity dopants and the light-induced photoelectrons exhibits strong spin coupling via exchange interaction which can further be modulated at will by additional excitation.
