In cases of higher CR (CR>100), active cooling devices can be used to enhance heat transfer efficiency between the photovoltaic cells, but inevitably, forced cooling devices consume additional electricity .
The research findings indicate: After integrating LAES cooling utilization into CPVS, the efficiency of the 4.15 MW photovoltaic module increased from 30 % to 37.33 %, representing a growth of 24.41 %.
In this context, Concentrated Photovoltaics (CPV) play a crucial role in renewable energy generation and carbon emission reduction as a highly efficient and clean power generation technology .
However, the implementation of this solution requires a suitable energy storage method. Liquid Air Energy Storage (LAES) has emerged as a promising energy storage method due to its advantages of large-scale, long-duration energy storage, cleanliness, low carbon emissions, safety, and long lifespan.
Concentrated Photovoltaics (CPV) are at the forefront of this transition due to their high efficiency and clean energy generation capabilities. However, CPV cell stability and reliability are compromised by high operating temperatures, necessitating effective cooling solutions.
The deployment of liquid air's cooling capacity in conjunction with a heat exchange process can significantly lower the operating temperature of CPV cells. By first exchanging heat between the ambient cooling water and the cold air derived from liquid air, we can achieve a more efficacious cooling medium.
