Abstract

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 = NH3 / SiH4) has the highest current, which is consistent with the results observed for the I-V characteristics of such heterostructures.

硅基高效太阳能电池的光电特性研究

本工作的目的是通过研究新材料和新方法来提高大面积薄膜太阳能电池的效率和稳定性。因此，我们正在研究一种新的概念，即将纳米颗粒集成到氮化硅(Si3N4)的增透层中，以提高太阳能电池的效率。在本文中，我们研究了硅(Si)纳米颗粒在基质中的应用，并给出了基于硅的薄膜溶液的太阳能电池的研究结果。光敏光谱研究结果的分析表明，nc-Si在光伏领域的应用潜力很大，可以改善硅太阳能电池由于吸收而在可见光范围内的光谱响应。增强光学在高能方面。通过对光电流的分析，发现比值R = 3(其中R为气体的比值R = NH3 / SiH4)的电流最大，这与对这类异质结构的I-V特性的观察结果一致。
