Reduce the cost of solar cells based on perovskites at fully printed Dmitry Lopatin1 , Oleg Baranov1, Dmitry Samarsky1, Elizabeth Korzhova1 1PhotoChem Electronics Co. Ltd., Russia, dimitrylsm@gmail.com The use of solar energy is currently still an expensive solution to provide itself with energy . Typical average household requires about 25 square meters of solar panels, the cost of which is about 15 thousand dollars and that's not counting the costly installation work . We develop technology that can significantly reduce the cost of solar panels by the almost complete automation of the entire cycle for technology such as the printer , allowing you to reduce the price to $ 100 per square meter at an efficiency of about 15%. In this solar cell does not contain rare components for which prices may rise in the future . All of this means that the panel is 5 kW cost of about $ 3 million could be recouped in less than 3 years Production readily scalable and can be used in other areas where high accuracy is needed when the layers obtained by a large area , for example in the production of batteries , fuel cells displays, printed electronics.
