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.

Solarwatt shuts down battery factory in Germany

Solarwatt says it will shut down its battery factory in Germany. Battery production at the Dresden facility will halt at the end of this year, and the company will move all battery and solar panel production to China.

Lead-free inverted perovskite solar cells without transparent conducting oxides may achieve 30% efficiency

Researchers in Nigeria have proposed to build inverted perovskite solar cells exclusively with all-inorganic transport materials and a lead-free perovksite absorber. Through a series of simulations, they showed these device may achieve efficiencies over 30% with low production costs.

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.

Renewable manufacturing costs up to 200% lower in China, says WoodMac

Wood Mackenzie says in its latest report that low prices and integrated supply chains allow Chinese manufacturers to supply more than 65% of total global demand for renewables equipment, with its exports growing by 35% between 2019 and 2023.

Gamesa Electric releases study on losses due to harmonics in PV plants

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.

Policy uncertainty creates ‘gap’ between hydrogen aims and reality, says BNEF

BloombergNEF (BNEF) says in a new study of 1,600 planned hydrogen projects that governments will miss their 2030 hydrogen targets. Analyst Adithya Bhashyam tells pv magazine that most of the announced projects to the end of this decade lack the key conditions for success.

Shedding light on tandem perovskite solar cell progress

Perovskite PV devices are set to become the next big thing in solar with market analysts at S&P Global Commodity Insights predicting 1 GW of production by the end of 2024, rising to 6 GW in 2025. Perovskite tandem devices are at the front of the queue for commercialization but their characterization presents technical challenges.

Global polysilicon prices hold steady, China polysilicon falls on weak demand

In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
