Methods for optimizing of the structure of the photovoltaic converters based on mono- and polycrystalline silicon with a photoluminescent coating
Abstract
There were analyzed of modern trends in the field of application of photoelectric converters in the implementation of the concept of "Green energy". It is shown that the main factor of low efficiency of photovoltaic converters based on polycrystalline and monocrystalline silicon substrates is the discrepancy between the absorption spectrum of the semiconductor and the spectrum of solar radiation. The advantages of the technology of applying a photoluminescent layer to the surface of a photoelectric converter for converting solar radiation into the long-wavelength part of the solar spectrum due to the phenomenon of the Stokes shift of photoluminescence are pointed out. Basic approaches to the synthesis of luminophor and the deposition of the microrelief structure on the surface of a silicon substrate are proposed. A mathematical model has been built to solve the problem of optimizing the structure of a photoelectric converter with a photoluminescent coating.
