Analysis of the efficiency of a solar cell with nano-dimensional hetero transitions

The optimal ratios of the parameters of a solar cell with nano-dimensional hetero junctions that provide maximum power efficiency are determined. It follows from the obtained relations that a solar cell with nano-dimensional hetero junctions can be constructed in such a way that its efficiency will always have the required high level. It is shown that such a controlled situation is possible in relation to a solar cell with nano-dimensional $p-n-$junctions created due to the phenomenon of self-organization on a substrate made of technical silicon. Such solar cells can contribute to improving the efficiency of solar energy, the formation of highly efficient, cheap photovoltaic converters.
