< p > International group of scientists have proven that perovskite solar elements can be improved by adding thin films from metal oxides. They posted & nbsp; article & nbsp; about their research in Nature's scientific journal.
< p >Due to the outstanding electrical, structural and optical qualities, thin films of metal oxides act as buffer layers to control the mobility of charge carriers and strongly affect the efficiency of energy conversion. Inorganic oxide materials also reduce the cost of panel production and increase their stability due to good moisture resistance.
< P > By the way, a company from Belgium has recently introduced & nbsp; solar films operating on any surface. It can generate 150 W/m & sup2; Electricity for efficiency in 17%.
< P > Researchers have applied oxides to the substrate by means of reactive evaporation with an electronic bundle, which involves sublimation of pure metals at different pressure of pure oxygen with subsequent thermal annea for 200 & Deg; c. As a result, uniform and dense films were formed on the entire surface. Using the measured refractive indexes in the computing model, scientists have shown that optimizing the design of the device using these films can increase the efficiency of energy conversion by more than 25%.
~ ~ < P > As noted by the authors, layers of metal oxides have already been used in different configurations of perovskitic devices for carrying a charge, but to achieve high efficiency of solar modules they need to be optimized, in particular, to find the optimal temperature for annealing. If new layers show good electrical properties, they will be able to use them in future photovoltaic devices unnecessarily in additional fine settings.
