A chemical tune up for better perovskites

Scientists in the United States took a closer look at the way charges move through a perovskite material, and found that replacing hydrogen in the material with a heavier isotope can both reduce thermal conductivity and increase carrier lifetime, potentially leading to more efficient solar cells. And the group expects continuing study of charge states and molecule dynamics to yield further important discoveries.

Canadian Solar preps to launch 600+ W module

Bigger PV module designs are now hitting the market, but the production of larger, more powerful solar panels is challenging. Canadian Solar is launching its new Series 7 modules with pv magazine in a webinar on Oct. 29. Our editorial team recently caught up with Canadian Solar’s chairman and CEO, Shawn Qu, and director of module R&D, Alan Xu, to discuss the company’s latest efforts to shake up the market.

Bayesian algorithm to reduce LCOE of bifacial projects

German researchers have proposed a new model, based on a range of parameters, to influence the LCOE of bifacial PV plants, with a focus on components, land costs, inclination angles, albedo, and weather conditions.

France to support BIPV solar tiles with additional incentives

Barbara Pompili, the French minister of ecological transition, recently announced new bonus incentives for BIPV projects during a visit to a Sunstyle factory that aims to produce 1 GW of “Made in France” solar tiles by 2025.

A stress test for all seasons

Scientists led by the U.S. National Renewable Energy Laboratory (NREL) have developed a new stress testing protocol for PV modules, one designed to simultaneously expose modules to multiple stresses, as they likely would be in the field. Putting modules through this test, the researchers have already been able to reveal new information regarding backsheet degradation, and they promise new insights into other degradation mechanisms both known and unknown as well.

New method to measure solar-powered hydrogen production

Indian researchers have used an “adaptive neuro-fuzzy inference system” to assess the performance of hydrogen production backed by a photovoltaic-thermal collector. They claim it can be applied to other hydrogen production systems.

Australian scientists shed light on perovskite problem

Australian researchers have made a significant discovery in the fight against light-induced phase segregation in next-generation PV cells.

BayWa r.e and Alliander develop solar-plus-hydrogen in northern Netherlands

The pilot project, consisting of a 50 MW solar plant and a utility scale electrolyzer, is planned to test how this combination may help reduce grid constraints in the country.

Hanwha Q-Cells moves to enforce court ruling related to patent infringement

The Korean manufacturer today announced it wants to enforce a ruling made in the regional court of Düsseldorf in June which prohibited rival Jinko Solar from making, selling, importing and distributing products which the court ruled had infringed one of Hanwha’s passivation patents.
