Opto-electro-thermal model to predict solar cell temperature, output
French scientists have developed a fully coupled opto-electro-thermal model that reportedly predicts solar cell behavior under real operating conditions in a standalone framework. They said the model can detect the impact of cell doping on the operating temperature and the temperature coefficient.
Radiative cooling for PV modules – challenges and prospects
A group of international scientists has investigated the potential use of radiative cooling in PV systems, in a newly published review focusing on challenges and opportunities for the passive cooling technology.
Radiative cooling-based solar cell with 50 mW/m2 of generation at night
Stanford University scientists have developed a solar cell with 24 hours of power generation via an embedded thermoelectric generator, which extracts power from the radiative cooler at night. Extra daytime power from excess heating comes from the cell itself.
Cooling PV modules with radiative sky cooling
French scientists have proposed the use of radiative sky cooling as a passive cooling technique to cut PV module temperatures by 10 C. They claim the method could improve performance by more than 5 W/m2.
