Sarcos has designed a robotic PV construction solution that delivers, detects, lifts, and places PV modules in large-scale solar plants. It has recently field tested and validated the prototype solution in a pilot project funded by the US Department of Energy.

Finnish and German researchers have assessed the role of seasonal hydrogen storage for PV prosumer households with a “least-cost” model at a global level up to 2050. They have found that seasonal hydrogen storage can only be expected in a niche, off-grid market.

Scientists in South Korea have developed a flexible, transparent solar cell with an average visible transmittance (AVT) of 88.3%. They have also created an n-type rear window layer to optimize bifacial operation.

Finnish researchers have studied different scenarios to convert a Nordic oil-heated townhouse into a carbon-neutral building. They dimensioned an off-grid PV-powered heat pump system using waste heat recovery from a hydrogen storage system and calculated its life-cycle cost. They concluded that the solution is less profitable than grid-connected systems.

Romania-based startup Photovoltaic Windows has developed an off-grid domestic hot water system powered by cadmium telluride (CdTe) photovoltaic semi-transparent glasses. It claims a 0.7 kW pilot installation on an apartment balcony in Bucharest resulted in annual savings of €1,100 ($1,202).

An international research group created a triple-junction perovskite solar cell with an efficiency of 24.3% and a quasi-steady-state efficiency of 23.3%. The prototype cell, which has been independently certified by the US National Renewable Energy Laboratory (NREL), features rubidium/cesium mixed-cation inorganic perovskites with a bandgap of around 2.0 eV to suppress light-induced phase segregation.

Daikin has started building its first heat pump factory in Lodz, Poland. The Japanese heating manufacturer will invest €300 million ($327.2 million) in the new facility, which is expected to start operations in July 2024.

The municipality of Aradippou, Cyprus, says it is looking for developers to build a 2.96 MW solar plant. The deadline for bids is May 12.

Hungary’s Platio has inaugurated a solar footpath in the Dutch city of Groningen. The installation consists of 2,544 monocrystalline Patio solar pavers with a 21.8% efficiency rating. It will generate 55,000 kWh of electricity per year and can purportedly withstand a pressure of 2 tons without microcracks.

LG Electronics North America has revealed plans to manufacture 100% electric heat pumps in the United States for the first time.
