U.S. scientists develop air-bridge thermophotovoltaic cells with 44% efficiency
U.S. scientists have developed a thermophotovoltaic cell that could be paired with inexpensive thermal storage to provide power on demand. The indium gallium arsenide (InGaAs) thermophotovoltaic cell absorbs most of the in-band radiation to generate electricity, while serving as a nearly perfect mirror.
Perovskites move into production
Perovskites remain a great hope for the future of the solar industry, once the possibilities of tunnel oxide passivated contact (TOPCon) and heterojunction PV have been exhausted. A look at the latest perovskite research shows that industry optimism is built on a strong foundation.
Solar peaks at 123% of grid, supplies 31% of California’s April electricity
The Golden State set multiple clean energy records in April, with solar power increasingly dominating the grid, supported by robust energy storage solutions.
Bladeless wind energy innovation aims to compete with rooftop solar
A compact, “motionless” wind turbine with a magnetic generator designed for large commercial rooftops provides 5 kW of capacity per unit. Aeromine Technologies secured Series A funding for scaling its innovative design.
Quantifying losses from harmonics in solar facilities
Gamesa Electric has released a white paper on losses due to harmonics in PV plants, including an independent study that compares the performance of ultra-low total harmonic distortion inverters.
Research shows repaired PV modules can perform with acceptable losses
A research group has demonstrated the technical feasibility of using repaired solar modules with satisfying results. It also warned, however, that there is an urgent need to define a protocol for evaluating the features of a “viable” repaired panel.
Renewables must triple by 2030 to hit net-zero by 2050, says BloombergNEF
BloombergNEF says in a new report that solar and wind must drive most emissions cuts before 2030 to stay on track for net-zero by 2050. Its net-zero scenario targets a combined solar and wind capacity of 31 TW by 2050.
NREL-led consortium releases PV reliability forecasting tools
The Durable Module Materials consortium (DuraMAT) announced in its latest annual report the availability of new PV forecasting tools, and new research results towards the goal of more reliable PV modules.
Strong state solar policies boost adoption of distributed energy
Of the 29 GW of solar installed in the U.S. in 2023, 31% was distributed solar, according to the Institute for Local Self-Reliance.
Researchers demonstrate 25%-efficient perovskite-cadmium tandem solar cell
University of Toledo researchers say the cell has a top perovskite cell with a transparent back contact made of indium zinc oxide and a commercially established cadmium telluride bottom device. They claim the champion tandem cell has the potential to reach a 30% efficiency.
