Abstract
Records show that in 2009 the efficiency of photoelectric conversion (PCE) of solar cells using Perovskites (PSCs) was 3.8% and nowadays it reaches 25.2%. In addition to being highly efficient, Perovskites (PVK) can be prepared with low-cost materials and techniques, making them an excellent technology to be commercialized. However, PSCs face long-term instability problems under realisti…
