Scientists at the University of California, Santa Barbara who are working with sodium-ion batteries have found that the unintended presence of hydrogen is to blame for many of the technology’s shortcomings in terms of degradation and performance loss. Keeping hydrogen out of the materials throughout production could allow sodium-ion batteries to achieve performance levels competing with their lithium-ion counterparts.

Chinese thin film manufacturer Hanergy has announced plans to integrate its CIGS modules into the 150,000 square meter rooftop of a ‘sky bridge’ project planned as part of a major ‘tech city’ project under construction in Shanghai.

A new paper published by scientists from the Massachusetts Institute of Technology examines the potential for integrating small solar cells into the wireless sensors needed to power the fast-growing internet of things (IoT) ecosystem, many of which are located indoors. This market could represent a unique opportunity for thin film PV technologies, and perovskites in particular, to reduce the risk inherent to ramping up commercial scale production.

Japanese materials company Toray has announced plans to open a facility for manufacturing battery separator films for use in lithium-ion batteries. The factory is expected to begin operations in July 2021 and will increase Toray’s production material for the component by around 20%.

Scientists at Pennsylvania State University have developed a new class of perovskite materials, which they say exhibits unique properties that could have several implications for the development of perovskite solar cells, as well as other electronic applications.

Scientists at Saudi Arabia’s King Abdullah University of Science Technology have set a new efficiency record of 21.09% for a single crystal perovskite. The researchers say this highlights a place for the technology to develop alongside the multicrystalline versions which are progressing toward commercialization.

Norwegian headquartered polysilicon manufacturer REC Silicon has announced that it will lay off another 100 workers at its Moses Lake facility in the western United States, as the factory heads into long term shutdown.

Engineers at the University of Utah have developed a tiny device which they say could increase the performance of PV panels and other electronic devices by converting energy lost as heat back into electricity.

Scientists at Russia’s Skoltech Institute of Science and Technology have demonstrated a solar cell with record high radiation stability. The scientists say the cells, based on an organic polymer compound, could be a strong candidate to meet the requirements of powering satellites in lower earth orbit.

Scientists at Saudi Arabia’s King Abdullah University of Science and Technology have demonstrated a system based on commercially available solar panels which can generate electricity and produce clean, drinkable water from seawater or otherwise contaminated sources.
