Italian researchers have outlined a four-step method to assess the technical feasibility of building-integrated PV (BIPV) projects in historical buildings. They applied the proposed approach to a courtyard building from the 16th century in the historical Italian town of Marcianise.

Imec has successfully integrated silicon heterojunction PV cells into curved surfaces, resulting in a 6% efficiency increase compared to passivated emitter and rear contact (PERC) half cells. The cells are suitable for applications in vehicle-integrated and building-integrated PV (BIPV).

France’s National Solar Energy Institute (INES) – a division of the French Alternative Energies and Atomic Energy Commission (CEA) – is developing ultra-thin TOPCon solar devices for space missions, in cooperation with the European Space Agency (ESA).

The China National Institute of Metrology has certified the result. The manufacturer claims it was able to increase the panel efficiency from 16.02% to 18.04% in a few months.

The new product utlizes propane refrigerant with a lower global warming potential and has a seasonal coefficient of performance (SCOP) of over 5. According to the manufacturer, it can achieve a flow temperature of 75 C and 100% heating output at outside temperatures of -15 C.

German researchers measured a PV-powered heat pump with battery storage in a single-family home in Freiburg, Germany, for a period of a year. It features smart grid-ready tech that adjusts operations based on the grid.

AEG is offering three versions of its new all-black solar panels, with power outputs of 435 W to 445 W and efficiency ratings ranging from 21.5% to 22.0%. They feature 108 half-cut monocrystalline cells with n-type technology.

Scientists in India have developed a 500 W seven-level inverter prototype based on switched capacitors. The device is reportedly able to achieve a high efficiency despite switching, conduction, and capacitor voltage ripple losses.

Sparc Hydrogen has successfully tested a green hydrogen tech prototype and is now advancing to a pilot plant study near Adelaide, Australia.

An international research team demonstrated that monolithic perovskite-silicon tandem cells do not suffer the same degree of reverse bias degradation that is typically seen in perovskite single junction solar cells under partial shading. They explained that the tandem devices are “protected” by the silicon subcell.
