GE Appliances unveils residential hybrid heat pump water heater
The U.S. manufacturer said its new heat pump water heater can provide up to 60% more hot water than standard electric water heaters. The system is available in 240 V and 120 V options and with a capacity ranging from 160 L to 190 L.
Indian scientists build 29.14%-efficient tandem solar cell with inverted top perovskite device
The researchers said they optimized the low-bandgap inverted perovskite cells through a passivating aluminum oxide (Al2O3) interlayer deposited via atomic layer deposition (ALD), which significantly helped improve device efficiency.
Scientists discover new failure mode in LECO-treated TOPCon solar cells
An international research team has observed a significant increase in series resistance in LECO-treated TOPCon solar cells after temperature and bias treatment. The scientists said they now need to conduct further investigations into its impact on cell efficiency, reliability, and bankability.
Unpacking the rationale behind low bids in the EU green hydrogen tender
BloombergNEF and Wood Mackenzie analysts spoke with pv magazine about the EU’s €992 million ($1.04 billion) hydrogen tender that drew record-low bids thanks to strong design incentives. They outlined the factors behind the tender’s competitiveness but cautioned that not all awarded projects may move forward.
PV-powered fine sand solar geyser for domestic hot water
The system is described by its creators as a cost-effective solution for water heating by storing thermal energy in fine sand. Techno-economic analysis indicated the system is economically viable for domestic water heating applications, with an initial capital cost of $278 and an expected lifespan of 25 years.
