About Gap processing on the four sides of photovoltaic panels
The gaps between the stepped panels increased the flow velocity, which promoted convective heat transfer to cool the photovoltaic systems. The gaps cooled the panels by allowing them to make more contact with incoming low temperature air.

Dye-sensitized solar cell (DSSC) was invented back in 1991 based on the photosensitization initiated by dyes on wide band-gap semiconductors such as TiO 2. It is a low-cost device for solar energy conversion into electricity due to inexpensive materials and ease of fabrication processes.
Furthermore, compared with water, EGDA has better wettability on glass, meaning that EGDA can penetrate the glass-EVA gap more easily. Finally, the mechanism of layer separation by EGDA was explored by SEM, FTIR, and GC–MS. This process is resource-sustainable, which can be expected to be applied on a large scale.

6 FAQs about [Gap processing on the four sides of photovoltaic panels]
What are the different cooling methods used in PV solar cells?
The cooling methods used are described under four broad categories: passive cooling techniques, active cooling techniques, PCM cooling, and PCM with additives. Many studies made a general review of the methods of cooling PV solar cells, especially the first three methods.
How do photovoltaic panels work?
Photovoltaic (PV) panels are one of the most important solar energy sources used to convert the sun’s radiation falling on them into electrical power directly. Many factors affect the functioning of photovoltaic panels, including external factors and internal factors.
Why do PV panels use phase change materials?
The use of Phase Change materials allows absorbing excessive thermal energy in PV panels, contributing to regulating their temperature and improving conversion performance (Ma et al., 2019). The advantage of using PCMs is that a great amount of heat can be dissipated from the PV module via the exploration of the PCM's latent energy (Ali, 2020).
Can Egda be used to separate glass-Eva in photovoltaic modules?
Non-toxic reagent EGDA was used to separate the glass-EVA in photovoltaic modules for the first time. The glass in 20 mm × 20 mm photovoltaic pieces can be separated adequately in 3 h. EGDA can be recycled by filtration to be reused. Solar cells can keep their initial size due to the moderate swelling ability of EGDA.
How does temperature affect the efficiency of solar PV panels?
An increase in temperature of the cell decreases the open-circuit voltage linearly, so the solar PV panel’s efficiency is decreased. But the short-circuit current scarcely ascended with the cell temperature (Joshi, Dincer, and Reddy 2009).
Can a TeG be integrated with a PV panel?
TEG Integrated with a PV panel will enhance its performance and minimize the amount of heat dissipation (Sahin et al., 2020). The output of a TEG generally varies non-linearly with the temperature since the properties of thermoelectric materials vary non-linearly with the temperature (Bjørk and Nielsen 2015).
