Test bench for aboveground compressed air energy storage systems
Researchers in Canada have created an experimental workbench for aboveground compressed air energy storage. Experimental data calibration reportedly ensured model accuracy with a mean absolute percentage error below 4.0%.
Egyptian scientists build PV-powered mini fridge with thermoelectric cooling
Egyptian researchers have developed a mini refrigerator powered by one to four thermoelectric units at varying voltages. They simulated and tested the system under different conditions, achieving a maximum coefficient of performance (COP) of 77.3%.
Scientists unveil results of full-year analysis on building-integrated photovoltaics
Scientists from Denmark have examined three façades installed on a mobile office container to conduct building-integrated PV experiments.
New cleaning tool for perovskite, organic PV roll-to-roll production equipment
A German research team has developed a precise cleaning process for electrode deburring in perovskite and organic solar PV roll-to-roll production lines. It is based on commercially available equipment from Germany-based Acp Systems.
Positive early results from first test of perovskite tandem solar cells in space
Helmholtz-Zentrum Berlin has reported strong initial results from its first test of perovskite tandem solar cells in space, where perovskite-silicon and thin-film cells on an OOV-Cube satellite are showing resilience to high radiation levels and possible “self-healing” from radiation damage.
Arriba Technologies launches solarized heating-cooling system
Arriba Technologies, a UK heating and cooling specialist, has developed a solar-integrated heating and cooling unit with a DC electrical system, all in a single package. It is installed at a 750 kW plant at Cambridge’s Rosie Hospital and won the Lighthouse Heat Pump Award at the European Heat Pump Association’s heat pump forum in September.
Mobile PV-powered EV charging stations for commercial, industrial sites
United Kingdom-based 3ti Energy Hubs has launched a portable electric vehicle charging station for 12 cars that it delivers to commercial and industrial sites where demand exceeds supply.
KAUST, Helmholtz-Zentrum Berlin present 31.2%-efficient blade-coated perovskite-silicon tandem solar cell
The perovskite-silicon tandem device has a two terminal configuration and a 2D perovskite layers at the bottom interface. It was able to retain around 80% of its initial efficiency for 1,700 h.
New model to assess performance of building-integrated photovoltaics based on PCM
Researchers in China have analyzed the effect of phase change material on BIPV, and created an artificial neural network to forecast its effect on system temperature. The proposed approach reportedly achieved superior predictive performance compared to earlier methods.
Multiple designs of photovoltaic-thermal collectors
Scientists have modeled eight different kinds of PVT systems, some with a glass covers and some without. They found the worst efficiency was achieved in uncovered systems with parallel round tubes.
