Abstract

Purpose: Photovoltaic solar energy conversion technologies represent promising pathways to clean and renewable energy production. Research on organic solar cells is actively developing, especially in the last decade it has attracted scientific and economic interest driven by the rapid increase in energy conversion efficiency. In recent years, luminescent materials capable of converting a broad spectrum of light into photons of a specific wavelength have been synthesized and used to minimize losses in the solar cell-based energy conversion process. This paper presents a study of the optical and luminescent properties of thin films of copper complexes C₆₂H₅₀Cu₂I₂N₈P₂.

Experimental: It is proposed to use this material as a re-emitting layer on the surface of a solar cell in order to increase the coefficient of performance (COP) of the latter by converting energy from the ultraviolet range to the visible range. A study of the volt-ampere characteristics of a pure single-crystal solar cell and a cell with an re-emitting copper complex layerhas been carried out.

Conclusions: It is shown that deposition of C₆₂H₅₀Cu₂I₂N₈P₂ on the surface of solar cells allows increasing the efficiency of converters by 1.45 % in the ultraviolet range at low economic costs. Mechanisms for enhancing energy conversion are discussed and recent experimental results on similar studies are analyzed
