Some Features of Photoelectrical Properties of Highly Efficient Solar Cells Based on Si
Аннотация
The aim of this work was to improve the efficiency and stability of large-area thin-film solar cells by studying new materials and methods. Thus, we are studying a new concept, which is to integrate nanoparticles into the anti-reflection layer of Si3N4 (silicon nitride), in order to increase the efficiency of solar cells. In this paper, we study silicon (Si) nanoparticles in a matrix and present the results of a study of solar cells with a thin-film solution based on Si. Analysis of the results of photosensitivity spectroscopy studies has shown us the potential of nc-Si for application in the photovoltaic region in order to improve the spectral response in the visible range of silicon solar cells due to absorption. enhanced optics on the high energy side. From the analysis of the photocurrent, it is found that the ratio R = 3 (where R is the ratio of gases R = NH <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> / SiH <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> ) has the highest current, which is consistent with the results observed for the I-V characteristics of such heterostructures.
