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 accu-mulation,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 super-hydrophobic 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 genera-tion compared to an ordinary PV panel in the spring of Shenzhen,China.
