Thermoacoustic refrigerator-heat pump with direct-coupling configuration

Researchers in China have designed a heat-driven thermoacoustic refrigerator/heat pump for room refrigeration. They said the system is easily combinable with PV energy and its coefficient of performance can reach up to 1.69.

Rio Tinto signs long-term PPA for 1.1 GW Australian solar plant

Resources giant Rio Tinto has signed Australia’s largest corporate power purchase agreement (PPA) to date. It has agreed to buy 100% of the output from European Energy Australia’s 1.1 GW Upper Calliope Solar Farm to provide renewable power to its aluminum operations in the state of Queensland.

All-perovskite triple-junction solar cell achieves 25.1% efficiency via new passivation technique

An international research team built the triple-junction device with dual bulk and interface passivation technique aimed at promoting halide homogeneity at the interface between the perovskite absorber and the hole-transport-layer. The 0.049 cm2 cell achieved a remarkable open-circuit voltage of 3.33 V and was also able to retain 80% of its initial efficiency after 200 h of continuous maximum power point tracking.

Solar canopies as a central pillar of IRA-driven energy transition

With so much of the space in United States cities allocated for parking, the dual pronged approach of the Inflation Reduction Act (IRA) – production tax credits to drive investment in domestic manufacturing and investment tax credits to attract consumer-side investment – means solar canopies can make a huge contribution to the net zero drive.
