Israel to provide incentives for hybrid solar inverters
Israel’s Ministry of Energy says it will exempt hybrid solar inverters from purchase tax and customs duties. It claims that these policy mechanisms will help during energy emergencies.
Reducing PV module temperature with cooled air from the ground
Researchers from Iraq have used computational fluid dynamics to simulate the operation of a 100 W panel with ground cooling. The proposed technique was reportedly able to reduce panel temperature by up to 28%, with power generation increasing by up to 6.5%.
ChatGPT can tell scientists how to build better perovksite solar cells, research says
An international research group has sought to build for the first time a perovskite solar cell with the help of ChatGPT. The experiment helped the scientists identify a series of materials for the cell composition and the results were cells with a higher power conversion efficiency compared to that of reference cells built without the material proposed by the large language model.
Chinese researchers build kesterite solar cell with certified efficiency of 14.2%
The solar cell was treated with multi-elemental alloying, which reportedly helped eliminate defects in the kesterite absorber, thus increasing cell efficiency. China’s National PV Industry Measurement and Testing Center confimed the results.
