Scientists discover new failure mode in LECO-treated TOPCon solar cells
An international research team has observed a significant increase in series resistance in LECO-treated TOPCon solar cells after temperature and bias treatment. The scientists said they now need to conduct further investigations into its impact on cell efficiency, reliability, and bankability.
Meyer Burger’s German subsidiaries file for insolvency
Meyer Burger said it filed for insolvency for its German subsidiaries, following intensive efforts to keep Meyer Burger Industries GmbH and Meyer Burger Germany GmbH operational.
U.S. scientists build antimony sulfide solar cell with 7.69% efficiency
Researchers at University of Toledo produced antimony sulfide (Sb2S3) thin film solar cells with 7.69% power conversion efficiency after determining optimal hydrothermal deposition, post annealing, and light soaking conditions. Stability tests showed more than 95% of initial efficiency after ten months.
Edinburgh Instruments unveils spectrofluorometer for perovskite, organic solar cells
The new FS5 v2 Spectrofluorometer is available as a benchtop system for fluorescence spectroscopy.
Estimating potential-induced degradation in PV systems used for water pumping
Researchers in Spain have developed a new method to estimated potential-induced degradation (PID) in solar modules used in PV-driven water pumping systems. The proposed approach can detect PID from the open-circuit voltage measurement of the system’s PV module strings.
China module prices steady amid bearish outlook
In a new weekly update for pv magazine, OPIS, a Dow Jones company, reports that TOPCon modules from China held steady at $0.083/W. Meanwhile, the spot price for U.S. TOPcon modules over 600 W was assessed this week at $0.263/W.
