An international research team has fabricated a quasi-2D perovskite solar cell with a special kind of phenethylammonium iodide (PEAI) salt to enhance hole extraction. The result is a 23.08%-efficient device that is also able to retain 95% of its initial efficiency after 900 hours.An international research team created a 3D/2D perovskite solar cell using a triple-cation perovskite absorber treated with phenethylammonium iodide (PEAI), a modulator that alters the perovskite film's surface energy and forms a quasi-2D structure without further annealing. "We are currently planning to set up an experimental ...Den vollständigen Artikel lesen ...
