Chinese scientists develop colorless solar concentrator for PV windows
The research team’s semi-transparent solar concentrator can be directly coated onto standard window glass. It uses liquid crystal films to reflect and guide circularly-polarized sunlight to solar cells installed toward the edge of a window. A 1-inch diameter prototype was found capable of directly powering a 10 mW fan under sunlight.
Canadian Solar presents 660 W ‘low-carbon’ heterojunction module with 24.4% efficiency
The new products are available in nine versions with power output ranging from 620 W to 660 W and power conversion efficiency spanning from 23.0% to 24.4%. Canadian Solar said the panels have a carbon footprint of 285 kg CO₂eq/kW, which is reportedly one of the lowest among all silicon-based solar modules worldwide.
Novel MPPT methodology uses grey wolf hunting as inspiration
Researchers have developed a maximum power point tracking algorithm based on the social hierarchy and hunting strategy of grey wolves. When tested under realistic shading conditions, the grey wolf optimizer achieved an average MPPT efficiency of 98.15%, significantly outperforming conventional MPPT methods.
