Technology and R&D

The HiKu7 CS 7N-MS series is available with power output ranging from 640-665 W and efficiency ranging from 20.6-21.4%. The panel, which is the most powerful product the company brought to the market to date, is considered ideal for utility-scale and commercial and industrial PV projects.

A scientist familiar with First Solar’s earlier efforts in CIGS makes the case for the CdTe pioneer to return to the technology.

Meyer Burger has extended its seven-year tie-up with the Swiss Center for Electronics and Microtechnology by three years. They aim to achieve module-level production efficiencies of more than 24%, while also cutting costs.

Covid-19 rescue measures such as delaying electricity bill payments pile added pressure onto energy companies already hit by pandemic-related falls in demand in a continent which a new study suggests is too dependent on donor aid for the development of renewables.

An international research team has analyzed all existing cooling technologies for PV panels and has indicated the current best options and future trends of research. According to its findings, active water cooling, although expensive and not particularly practical, is the most effective cooling technique while passive cooling systems, despite being easy to apply, have still limited possibilities.

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.

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.

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.

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.

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.
