All-perovskite tandem PV cell based on carboranes hits 27.2% efficiency
Researchers have developed a thermal regulation strategy to improve the performance of inverted tin-lead perovskite tech for all-perovskite tandem solar cells. It has an efficiency of 23.4% and contributed to a 27.2% efficiency in a tandem cell while ensuring stability.
US, Canada ramp up solar glass plans
With PV module capacity ramping up, glass suppliers have been investing in new solar glass production capacity. As in India and China, new facilities are popping up in North America, with unique twists to ensure competitiveness, such as using recycled material.
Cadmium-doped perovskite solar cell achieves 22.7% efficiency
A Chinese-Canadian research group has utilized for the first time a cadmium iodide doping technique to stabilize the blade coating process in the manufacturing of solar cells based on formamidinium lead iodide (FAPbI3) perovskite. The academics built a cell showing a considerable increase in efficiency compared to an identical device without cadmium doping.
3D printed clamps for front-surface PV mounting on wood racking
A research team proposed a new PV mounting solution relying on two types of spacers and two types of clamps that can be printed with common printing materials. The cost of the different solutions presented varies from CAD1.50 ($1.10) to CAD3.83.
Research shows high-albedo ground reflectors increase bifacial solar plant yield by up to 4.5%
Tests conducted by Canadian researchers at the NREL’s testing field in Colorado have shown that ground reflectors based on high-density polyethylene can significantly increase bifacial PV plant performance. They stressed the profitability of this technology is strictly dependent on the location and warned avoiding to combine it with inverter clipping.
