Over the past seven years, the scientific community is well advanced in the development of solar panels . This is based on the crystal structures of the widest possible choice of materials unifying feature which is considered a compound of organic molecules with metals. Perovskite promise to be cheaper to produce than a classical solar cells based on silicon. Also, they can take any complex shape if the cells produce a thin film structure, which is also problematic for silicon. That's just the original efficiency perovskites was at the level of 3%, whereas the efficiency of silicon photocells long been close to 25%.
To date, the effectiveness of the cells of the perovskite is close to 22%. New experiences with this class of materials suggest that soon will be found possible to increase the efficiency of photocells on perovskites to 30%. According to scientists from the Lawrence Laboratory at Berkeley, a detailed study of perovskite cells created in the laboratory revealed serious heterogeneity of structure.
The difference in the development of the voltage reached 0.6 V. There was also a significant difference in the resulting current in the conversion. Scientists have speculated that if we manage to grow crystals with only a high performance areas, the efficiency of the photocells of the perovskite can reach the mark of 30%. . The trick here is that scientists have learned how to "map out" cells with very high resolution, and it points to move to the selection of the necessary materials. In other words, in the laboratory of Lawrence created a kind of compass that can point the way to a highly effective and relatively low-cost solar panels.
