Using shunts to spot PV module degradation
Scientists in Ireland investigated the effect of shunt resistance on a PV cell’s electrical performance. The group says its finding could potentially lead to the development of models for early detection of various forms of cell degradation, allowing for intervention to repair or replace components before major power losses occur.
GreenH building 1 GW electrolyzer fab in India
The company’s manufacturing plant in Haryana will produce proton exchange membrane (PEM) electrolyzers based on the technology from its Spanish parent firm H2B2 Electrolysis. The plant will start production by October.
TOPCon PV modules outperform PERC by more than 5% in energy yield tests
A study by TÜV Nord in Malaysia shows that the latest generation of tunnel oxide passivated contact (TOPCon) modules surpass their older rivals on energy yield. The researchers compared n-type TOPCon modules with older p-type PERC modules, both manufactured by JinkoSolar over a three-month period earlier this year. The newer product showed an energy yield 5.69% higher than its PERC counterpart.
India installed 6.8 GW of solar in H1 2023
Capacity addition in the rooftop solar segment stood at 2,294 MW, which is higher than the yearly rooftop PV installations of 2022.
German research institute unveils 99.74% efficient power electronics for solid-fuel heat pumps
Germany’s Fraunhofer Institute for Applied Solid State Physics (IAF) has developed an ultra-efficient circuit topology for voltage converters with an electrical efficiency of 99.74%. The tech could considerably raise the coefficient of performance for electrocaloric heat pumps and the scientists are now considering components based on semiconductor gallium nitride (GaN) for higher power density and efficiency.
