Researchers in Bangladesh have designed a dual-junction tandem solar cell with a bottom device based on iron disilicide (FeSi2), an emerging absorber material know for its high thermal stability and good optoelectronic properties. Their simulation showed the advantage of combining the larger bandgap of the top cadmium telluride cell and the smaller bandgap of the bottom FeSi2 cell.

Australian researchers have found that if 10% of vehicles are electric and utilize V2G connections, they could reduce peak electricity demand at local substations by 6% and save car owners hundreds of dollars per year on charging costs.

A new measurment and solar simulator instrument designed for perovskite-silicon tandem cells and encapsulated mini-modules is the latest product from a collaboration between Canadian solar simulator supplier G2V Optics and U.S.-based measurement instrumentation company Sinton Instruments.

The module has a size of 143 mm x 143 mm and an active area of 204.11 cm². The result was certified by the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE).

An NREL team finds that lead times for transformers has grown fourfold in three years, with orders sometimes taking two years. Additionally price increases of four to nine times have been reported in the past 3 years.

The new solar cell achieved a maximum power conversion efficiency of 23.75% and a certified efficiency of 23.64%, thus beating the previous world record of 23.35% achieved in 2019 by Japan’s Solar Frontier. The result was confirmed by the Fraunhofer ISE.

Looking back at the first full year since passage of the Inflation Reduction Act, the U.S. Solar Market Insight, Year-in-Review 2023 shows that the legislation has skyrocketed the industry and will have a lasting economic impact in terms of energy, jobs and investment opportunity.

Printed flexible solar cell technology developed by Australia’s national science agency has been successfully launched into space as part of billionaire Elon Musk’s Space X’s Transporter-10 mission.

The oil giant expects the facility to produce about 2.2 tons of hydrogen per day by 2025.

Adding residential solar or commercial-scale electric vehicle chargers on a utility’s distribution feeder may require the utility to conduct power flow calculations. Duke Energy can now complete those studies in hours, an Amazon executive said at a policy forum held by ACORE.
