Оптичні властивості матеріалів для сонячних елементів

Abstract

This paper examines the optical properties of materials used in solar cells and the methods for their measurement. Key parameters such as the refractive index, absorption coefficient, reflectivity, and emission spectra are analyzed for their impact on the efficiency of photovoltaic converters. The study explores the role of various semiconductor materials, including crystalline, nanocrystalline, and amorphous compounds, in optimizing solar cell performance. Special attention is given to modern approaches for enhancing light absorption and minimizing energy losses, which are crucial for improving the efficiency and cost effectiveness of solar energy systems.
