‘Shallow defects’ key to high efficiency of perovskite solar cells, say researchers
Researchers at the Jülich Research Center in Germany have used novel photoluminescence measurements to analyze the recombination of charge carriers in perovskite solar cells. They have found that the loss of charge carriers in perovskite devices works differently from other types of PV cells.
Perovskite-silicon tandem solar modules must ensure degradation rate of 0.4%/year to compete with crystalline silicon
Researchers from Saudi Arabia’s King Abdullah University of Science and Technology (KAUST) investigated the commercial prospects of perovskite-silicon tandem PV technologies and found that, in order to bring them closer to market maturity, their cost should not exceed by 30% that of crystalline silicon counterparts. Their roadmap stresses the importance of reducing perovskite degradation and improving product stability.
Perovskite solar module based on new interconnection tech achieves 21.37% efficiency
Chinese solar perovskite specialist Mellow Energy and the Jinan University developed a new manufacturing process for perovskite solar modules that enables the formation of a protective layer at the interface between the perovskite absorber and the electron transport layer. This prevents the effusion of volatile components from the perovksite film.
Grew Energy to build 2.8 GW wafer, solar cell factory in India
Grew Energy has signed a $457.37 million deal to set up a 2.8 GW factory in India. The state government of Gujarat will facilitate approvals for the manufacturing unit.
Solar wafer prices stabilize with potential for future price hike
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
Greenvolt secures 1.2 GW in Polish auction
Greenvolt Power, a Portuguese independent power producer, says it was awarded 1.2 GW of capacity for six battery energy storage systems (BESS) in a recent renewable energy auction in Poland, claiming it was the “top winner.”
More than 2 GW of PV installed in Austria in 2023, predicts analyst
Austrian PV Technology Platform Vice Chair Hubert Fechner tells pv magazine that he is confident that more than 2 GW of solar capacity was installed in Austria last year – and the figure could be as high as 2.5 GW.
Dracula Technologies integrates organic solar cell into flexible storage device
Dracula Technologies has developed a new indoor technology for its organic photovoltaic (OPV) cells. It designed the tech to replace traditional batteries in connected devices.
Machine learning algorithm for inverter fault monitoring, prediction
The new algorithm monitors the inverter subsystems and sends alarms when maximum and minimum values are reached. It analyzes data and categorizes variables according to historic values.
Swiss perovskite startup sets up indoor solar cell manufacturing
Indoor solar cell developer, Perovskia Solar, is setting up a factory in Switzerland that may reportedly print 1 million of its custom-designed perovskite devices annually. It targets the market for self-powering consumer electronics and internet-of-things devices, such as fire-alarms, fitness trackers, and sensors.
