Abstract

Photovoltaic (PV) power generation is highly regarded for its capability to transform solar energy into electrical power. However, in real-world applications, PV modules are prone to issues such as increased self-heating and surface dust accumulation, which contribute to a reduction in photoelectric conversion efficiency. Furthermore, elevated temperatures can adversely affect the components’ operational longevity. To augment the efficiency and extend the lifespan of PV modules, it is crucial to implement cooling strategies and periodic surface dust removal. In this research, we introduce a composite PV module design that amalgamates a hygroscopic hydrogel with self-cleaning attributes. The design incorporates a superhydrophobic polydimethylsiloxane (PDMS) film as its exposed surface layer and employs a PAM-CaCl₂-SiC hygroscopic hydrogel for rear cooling. This arrangement is intended to facilitate efficient surface self-cleaning and passive cooling of the composite PV module. Experimental studies were conducted to evaluate the performance of this innovative composite PV module design, and the results showed that the composite PV panel had an increase of about 1.39% in power generation compared to an ordinary PV panel in the spring of Shenzhen, China.

通过自冷却和自清洁设计提高转换效率的三明治结构太阳能电池

光伏（PV）发电因其将太阳能转化为电能的能力而备受推崇。然而，在实际应用中，光伏组件容易出现自热增加和表面积尘等问题，导致光电转换效率降低。此外，温度升高也会对组件的使用寿命产生不利影响。为了提高光伏组件的效率并延长其使用寿命，实施冷却策略和定期清除表面灰尘至关重要。在这项研究中，我们介绍了一种复合光伏组件设计，它将吸湿性水凝胶与自清洁属性结合在一起。该设计将超疏水性聚二甲基硅氧烷（PDMS）薄膜作为其暴露的表面层，并采用 PAM-CaCl2-SiC 吸湿水凝胶进行后部冷却。这种安排旨在促进复合光伏组件的高效表面自清洁和被动冷却。实验研究评估了这种创新型复合光伏组件设计的性能，结果表明，在中国深圳的春季，复合光伏板的发电量比普通光伏板增加了约 1.39%。
