The chemical origin of the p-type and n-type doping effects in the hybrid methylammonium–lead iodide (MAPbI 3 ) perovskite solar cells

In the present Communication we discuss a field-induced and photoinduced self-doping chemistry resulting in the formation of the positively and negatively charged vacancies in the MAPbI3 perovskite films. These vacancies induce p-type and n-type doping of the perovskite absorber leading to the reali... View More
