U.S. scientists claim 15-fold performance increase for solar thermoelectric generator
A research team have fabricated a solar thermoelectric generator (STEG) that is reportedly 15 times more efficient than current state-of-the-art devices by concentrating on the managing the hot and the cold sides of the device rather its semiconductor materials.

Despite low gas prices, solar, wind remain cheapest sources of power in U.S.
Renewables remain cost-competitive in the United States despite rising natural gas competitiveness, according to Lazard’s 2025 “Levelized Cost of Energy+” report, which estimates combined cycle gas at $0.048/kWh to $0.107/kWh, solar at $0.038/kWh to $0.212/kWh, and nuclear at $0.141/kWh to $0.220/kWh.
Carrier debuts residential heat pump for cold climates
The U.S. heating specialist said its new heat pump system can operate “reliably” at -22 F and achieve 100% heating capacity at 1.4 F, with full cooling capacity being achievable at 122 F.
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.
MIT scientists developing silicon solar cell based on singlet exciton fission
Scientists in the United States have designed a microwire solar cell that could reportedly enable the coupling of singlet fission with silicon. Key to their achievement was an interface that transfers the electrons and holes sequentially into silicon instead of both at once.
All solar cell efficiencies at a glance – updated
