Last modified: June 10, 2024 Researchers have created a comprehensive model of the circular water flows in a solar cell factory with a production capacity of 5 gigawatts (5GWp) per year. The results show that a reduction of up to 79 percent in the water consumption and up to 84 percent in the wastewater is possible.
Researchers from the Technical University of Berlin, Rena Technologies GmbH, and the Fraunhofer Institutes for Building Physics IBP and for Solar Energy Systems ISE have for the first time created a comprehensive model of the water flows in a solar cell factory with a production capacity of 5 gigawatts (5GWp) per year.
Simultaneously, sub-bandgap photons directly transmit to the absorber on the backplate for photothermal conversion, contributing to seawater desalination. In addition, during the operation of the solar cell, a portion of the energy dissipates as heat, which can be further utilized by the lower stages.
4. Conclusions In summary, a solar photovoltaic-thermal system capable of cogenerating electricity and freshwater is proposed by coupling semi-transparent solar cells and multistage interfacial desalination, thereby improving the utilization of the full solar spectrum.
Significant efforts have been devoted to the integration of combined solar cells and desalination in PVT configurations, aiming to generate electricity and produce freshwater simultaneously [, , ]. This approach is motivated by the fact that solar cells tend to generate more power at lower temperatures than at higher ones .
Using this model as basis, they tested the introduction of two different strategies for circular water use. The results show that a reduction of up to 79 percent in the water consumption and up to 84 percent in the wastewater is already technically possible with today's production technologies.

The optimal approach to enhance solar panel efficiency and decrease the degradation rate is to lower the temperature range of the surface area. It will be applied by allowing the panels/modules to be cooled and lessening the heat stored in the solar cells through an operation. In the research using experimental methods, the solar panels used have a …
