Improving perovskite solar cell performance with cadmium telluride buffer layer

An international research team has conducted a series of simulations to investigate how a cadmium telluride buffer layer may help increase efficiency and stability in perovskite solar cells. Their experiment showed that cell efficiency may climb from 11. 09% to 23. 56%. A group of scientists led by the University of Agriculture Faisalabad in Pakistan have proposed to improve the efficiency of perovskite solar cells by adding a buffer layer (BL) made of cadmium telluride (CdTe), which reportedly enhances extraction of charge carriers while reducing device defects. The researchers explained that ...
