Quantum-based energy management method for PV-powered buildings
Scientists from Cornell University combined quantum computing with model predictive control to manage the energy of two PV-equipped university buildings. Compared to deterministic approaches, the quantum strategy achieved a 6.8% improvement in energy efficiency and an annual reduction of 41.2% in carbon emissions.
Canadian Solar debuts 660 W TOPCon solar panel with 24.4% efficiency
The new products are available in seven versions with power output ranging from 630 W to 660 W and power conversion efficiency spanning from 23.3% to 24.4%.
Silver-lean screen-printing can reduce silver use in TOPCon solar cells by 40%
An international research team has developed a metallization technique for TOPCon solar cells that can reportedly reduce silver usage in the devices’ rear side by 85%. The scientists replaced the commonly used Ag fingers with intermittent Ag dashes for contact formation and Ag-free fingers and busbars for electrical conduction.
