Inverted perovskite solar cell with 21.85% efficiency via surface modulator
A UK research group has used surface modulators to reduce non-radiative recombination in perovskite solar cells. They used 2-TEAI organic halide salt to build a cell with high power conversion efficiency and stability.
FoxEss unveils compact single-phase inverters for residential PV
FoxEss has released new inverters with nominal power ranging from 0.7 kW to 3.3 kW, a maximum efficiency rating of 97.4%, and a maximum European efficiency of 96.8%. They measure 290 mm x 220 mm x 116 mm and weigh in at 5.4 kg.
Huawei, garment makers jointly target 2 GW of rooftop solar in Bangladesh
China’s Huawei has partnered with the Bangladesh Garment Manufacturers and Exporters Association (BGMEA) to deploy rooftop PV on top of 4,000 apparel factories.
PV-powered thermoelectric cooling for air conditioning in buildings
Scientists have proposed a way to combine thermoelectric modules (TEMs) with rooftop PV to support heating, ventilation and air conditioning in buildings. They designed a wall-integrated TEM to heat and cool adjacent rooms.
Indonesia may add 66 GW of solar by 2030, says IRENA
The International Renewable Energy Agency (IRENA) says that solar could become the backbone of Indonesia’s energy system by 2030. However, the nation’s own expectations are still far off from IRENA’s scenarios.
India’s SECI launches 1.2 GW hybrid wind-solar tender
Solar Energy Corp. of India (SECI) said developers have until Dec. 12 to submit bids for 1.2 GW of wind-solar-storage hybrid capacity. The projects will be developed on a build-own-operate basis, anywhere in India.
Australian miner signs baseload PPA contract with Neoen for 24/7 renewables
BHP has signed a 70 MW baseload renewable energy contract with Neoen to meet 50% of the energy demand of its Olympic Dam mining operations in South Australia.
US utility-scale solar slowed in Q3
US solar had its worst quarter in two years in terms of deployment, due to global supply challenges that slowed growth, delayed projects, and drove up prices.
Equinor acquires Danish solar developer
Equinor is set to fully acquire developer BeGreen, which has a project pipeline of more than 6 GW in Denmark, Sweden and Poland.
Air-source heat pump for harsh, cold climates
Carrier will soon begin field tests for a prototype air-source heat pump for cold climates. It is designed to provide high-efficiency heating performance in harsh climates with temperatures equal or below negative 29 degrees Celsius, while being grid-interactive. The US-based heating tech specialist expects to commercialize the solution by 2024.
