Abstract

This article presents the results of an experimental study of a photovoltaic thermal battery (PVTB) and a photovoltaic module (PVM) based on a thin-film structure installed on the heliopolygon of the Department of Alternative Energy Sources (AESs) of Tashkent State Technical University. A brief review of research on PVM cooling technologies and the creation of PVTB installations has been conducted. The data from the experimental study were processed. The dynamics of changes in the external parameters and characteristics of PVM and PVTB are presented graphically, as well as a comparison of the values of the corresponding parameters are given in tabular form. According to the results of the conducted research, the surface temperature of the PVTB decreased by an average of 6.3°С relative to the temperature of the PVM. Due to the developed module cooling technology, the electrical power of the PVTB compared to the power of the PVM increased by an average of 5.3 watts or 10.3%. According to experimental data, 122 L of heated water was produced during the time of the experiment from a useful area of 0.7 m² of PVTB, with an average temperature of 38.1°C. This installation allows for simultaneous electricity generation and water heating. These advantages create conditions for the use of this installation in the power supply and heated water supply of household needs of consumers.

自然条件下的薄膜光伏热电池实验研究

摘要本文介绍了对安装在塔什干国立技术大学替代能源系（AESs）日光垄上的光伏热电池（PVTB）和基于薄膜结构的光伏模块（PVM）进行实验研究的结果。本文简要回顾了有关 PVM 冷却技术的研究和 PVTB 装置的创建。对实验研究的数据进行了处理。PVM 和 PVTB 外部参数和特性的动态变化以图表形式呈现，相应参数值的比较以表格形式给出。研究结果表明，相对于 PVM 的温度，PVTB 的表面温度平均下降了 6.3°С。由于开发了组件冷却技术，PVTB 的电功率与 PVM 的电功率相比平均增加了 5.3 瓦或 10.3%。实验数据显示，在实验期间，0.7 平方米的 PVTB 有效面积产生了 122 升热水，平均温度为 38.1°C。该装置可同时发电和加热水。这些优势为将该装置用于满足消费者的家庭供电和热水供应需求创造了条件。
