In this work, we developed an innovative approach to self-grow single crystalline CH₃NH₃PbI₃ directly on polycrystalline FTO/TiO₂ substrate, with which n-i-p type of perovskite solar cells were fabricated. The single crystalline nature of CH₃NH₃PbI₃ has been confirmed by X-ray diffraction and high resolution transmission electron microscopy, and it is observed that they possess smaller optic band gap and longer carrier life time. Highly efficient charge extractions occur at the interface between electron collecting TiO₂ and photo-harvesting CH₃NH₃PbI₃, resulting in a maximum short-circuit current density of 24.40 mA/cm². The champion cell possesses a photovoltaic conversion efficiency of 8.78%, and there are still substantial room for further improvement, making it promising for the perovskite solar cell applications.
