Mobile solar system for farms
India’s Vivasvan Solar has designed a foldable solar structure mounted on a trolley. The system has mechanisms to prevent damage to the panels during transit and is especially useful for agricultural farms.
Das Solar claims record open-circuit voltage of 730 mV for n-type solar cell
Das Solar has achieved a world-record open-circuit voltage of 730 mV for an M10 n-type tunnel oxide passivated contact (TOPCon) solar cell, with a power conversion efficiency of 26.24%, according to the Chinese Academy of Sciences Institute of Electrical Engineering.
Ascent Solar acquires Swiss thin-film solar module maker Flisom
Ascent Solar says its acquisition of Flisom will triple its production capacity.
Translucent tandem perovskite-perovskite solar cells for BIPV
An international research group has made translucent perovskite solar cells to maintain decent levels of average visible transmittance (AVT) while offering higher efficiency. They tested different module and cell configurations and produced a two-terminal, perovskite-perovskite tandem device with an efficiency of 17.7% at 12% AVT.
Dust removal for solar panels via electrostatic cleaning
A Jordanian research team has designed a cleaning technique for solar modules that uses static electricity to remove dust from panel surfaces. The system features an electrostatic ionizer that reduces attraction between dust particles and their accumulation on modules, improving their energy yield.
Plug-and-play PV system for garden fences
German PV product supplier Green Akku says that its new PV system can be vertically attached to fences. It reportedly generates more solar power, even in winter.
Mitani Sangyo unveils solar carport for bifacial panels
Mitani Sangyo, a Japanese industrial conglomerate, says that its new PV carport design is particularly suitable for snowy areas, as it offers snow load resistance of 150 cm.
Agrivoltaics for grape farms
Researchers in Hong Kong have designed an agrivoltaic system that uses blockchain tech and smart contracts to reduce uncertainties between PV system operators and grape farmers. The proposed system uses rainwater to clean solar panels and provide irrigation.
PV-powered underground heat exchanger for buildings
Researchers in India have designed a PV-powered earth-to-air heat exchanger to provide buildings with space heating and cooling. They say the proposed system could result in an annual energy gain of 8116.7 kWh.
Solar panels on downed Chinese balloon could support advanced radar
The US authorities took down a Chinese balloon off the coast of South Carolina earlier this year that featured contained 10 kW of solar capacity – similar to a typical rooftop PV installation.
