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.

1. Printable solar cell
• Efficiency of 12-15%, consist of metal oxides are used,
conducting polymers, organometallic compounds, without raw
materials, light absorption by 87% (black)
• The cost price: $ 15-20 per square meter, life time 10 years
• 100-150 W from sqr. meter, 80 watts on average per day
• Lightness, flexibility, impact resistance,
• 30% better work in an oblique and scattered light
• Print speed setting 5 sqr. meters per hour
• Vertical accuracy of 10 nm to 200 nm, horizontal
• Installations for the production of easily scalable and can be used
in other industries
