Analysis of the role of nano-objects in the cheaper silicon solar cells

The analysis of technological capabilities ensuring the reduction in the cost of solar cell parameters is carried out.
The possibility and economic expediency of using as a substrate solar cells of technical silicon for a mass transformation of solar radiation into electricity is justified. The second contact material must be a nanoscale cluster from the family of lead chalcogenides (PbS, PbTl and PbSe).
It is shown that the cheapening, stable and long-lasting functioning of solar panels is achieved when they consist of solar cells with fundamentally different and numerous contact structures (they must be created using a new technology with a combination of contacting semiconductors that is unconventional for solar energy—one of them is nano-different–macro material).
