New cleaning tool for perovskite, organic PV roll-to-roll production equipment
A German research team has developed a precise cleaning process for electrode deburring in perovskite and organic solar PV roll-to-roll production lines. It is based on commercially available equipment from Germany-based Acp Systems.
Longi Green Energy sets world record for solar module efficiency at 25.4%
China’s Longi Green Energy has set a new world record for crystalline silicon solar module efficiency with its independently developed hybrid passivated back contact (HPBC) 2.0 module, achieving a conversion efficiency of 25.4%, according to a certification report from Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE).
‘TOPCon technology comes with three or four relevant risks that should be known’
The results of this year’s Kiwa PVEL scorecard have shown that TOPCon technology is more vulnerable than PERC, and the failure rate at BOM level has increased to 41%, the highest in history, according to the testing lab.
Mobile PV-powered EV charging stations for commercial, industrial sites
United Kingdom-based 3ti Energy Hubs has launched a portable electric vehicle charging station for 12 cars that it delivers to commercial and industrial sites where demand exceeds supply.
KAUST, Helmholtz-Zentrum Berlin present 31.2%-efficient blade-coated perovskite-silicon tandem solar cell
The perovskite-silicon tandem device has a two terminal configuration and a 2D perovskite layers at the bottom interface. It was able to retain around 80% of its initial efficiency for 1,700 h.
New model to assess performance of building-integrated photovoltaics based on PCM
Researchers in China have analyzed the effect of phase change material on BIPV, and created an artificial neural network to forecast its effect on system temperature. The proposed approach reportedly achieved superior predictive performance compared to earlier methods.
Multiple designs of photovoltaic-thermal collectors
Scientists have modeled eight different kinds of PVT systems, some with a glass covers and some without. They found the worst efficiency was achieved in uncovered systems with parallel round tubes.
JinkoSolar announces new TOPCon solar modules with efficiency of 24.8%
The Chinese manufacturer said the new Tiger Neo 3.0 modules are available in two versions with outputs of 495 W and 670 W.
Equipping transport trailer fleets with solar PV for fuel savings
Dutch solar PV systems integrator IM Efficiency has launched a complete solar PV system that includes battery and energy management system to power electrical systems on freight carrying trucks and transport trailers.
Trina Solar claims 25.9% efficiency for large-area industrial TOPCon solar cells
The Chinese manufacturer said the result was confirmed by Germany’s Institute for Solar Energy Research in Hamelin.
