PVT-assisted heat pump for residential water heating
A group of scientists in China has designed a residential heat pump system with a potential cofficient of performance of 4.271 at -5 C. The system is reportedly able to adjust the required pressures based on solar irradiance intensity and ambient temperature
All floating PV technologies at a glance
An international research team has produced a comprehensive overview of more than 300 works of published literature on floating PV, spanning 2013 to 2022. The scientists laid out the benefits and challenges of the technology and pointed to gaps that should be filled with future studies.
Australian state awards permit for 1.3 GW pumped hydro station
Former Australian Prime Minister Malcolm Turnbull has secured a contract to develop two large-scale pumped hydro projects on water reservoirs owned by the New South Wales government.
Performance assessment of air-source heat pumps in office buildings
Scientists have analyzed the performances of two air-source heat pumps in two small office buildings in China during the heating season. They identified the instantaneous load of the building as a critical cause of low energy efficiency.
Fully printable flexible perovskite solar cell achieves 17.6% efficiency
Developed by scientists in Canada, the 0.049 cm2 solar cell was built in ambient air fabricationand with a reactant known as phenyltrimethylammonium chloride (PTACl). It achieved an open-circuit voltage of 0.95 V, a short-circuit current density of 23 mA cm−2, and a fill factor of 80%.
Enhancing PV performance with graphite-based thermoelectric generator
Indian scientists have built a PV system coupled with a thermoelectric generator using graphite as a heat dissipator. The graphite-based system achieved a higher output and temperature gradient than a reference system without heat dissipation.
The Hydrogen Stream: Luxury regions invest in marine hydrogen services
SBM Offshore has installed a floating facility in Monaco to produce green hydrogen from renewables, while Axpo and its partners have revealed plans to use hydrogen to power a passenger vessel in Switzerland.
Premier Energies unveils 590 W TOPCon bifacial PV modules
Premier Energies says its n-type TOPCon bifacial glass-backsheet modules are available in power outputs of 555 W to 590 W, with an efficiency rating of up to 22.83%.
Socomec releases new modular energy storage system
Socomec says its new modular energy storage system includes a converter and up to six battery cabinets. At maximum capacity, it can store 1,116 kWh.
Inverted perovskite solar cell with 2D/3D heterojunctions achieves 25.6% efficiency
An international research team claims to have achieved optimal passivation in inverted perovskite solar cells by applying thin layers of low-dimensional perovskite on top of a 3D perovskite film. The resulting cell achieved an open-circuit voltage of 1.19 V, a short-circuit current density of 24.94 mA cm2, and a fill factor of 85.9%.
