Australian manufacturer Greatcell has built a cell with roll-to-roll coating technology. It designed it without a hole transport layer (HTL) and used carbon composite back contacts, which offer excellent electrical conductivity.

Chinese energy giant State Power Investment Corp. (SPIC) has switched on a pilot facility at 4,000 meters above sea level. It plans to complete the solar park by September 2023.

Scientists in South Korea have used a triboelectric generator and an electrodynamic dust shield to develop a panel-cleaning system that can be activated by footsteps. They said the system can remove more than 70% of accumulated dust with the pressure of just 12 footsteps.

Aerocompact’s new CompactFLAT GS mounting structure can be installed 40 cm above rooftop surfaces, with tilt angles of 10 and 15 degrees. The company says the product is ideal for bifacial solar arrays and green rooftops.

JinkoSolar has set another world record for n-type solar cell efficiencies with its TOPCon technology, this time reaching 26.1%. The new record was confirmed by China’s National Institute of Metrology.

Japanese scientists have built a perovskite solar cell without methylammonium to improve the device’s thermal stability. The cell showed better efficiency and stability under standard testing conditions.

Nilar International began manufacturing the ReOX reusable batteries at its factory in Sweden. The natural aging process of the battery is reversible and the battery is reportedly able to operate at full capacity at least three times.

Sprsun has developed a monobloc heat pump that is reportedly easier and faster to install. The product features a 3 kW/220 V electric heater, a water pump, an expansion tank measuring 5 liters, a three-way valve, and an 18 A AC contactor.

Germany-based AE Solar said its new panels have a temperature coefficient of -0.35% per degree Celsius and come with a 30-year power output guarantee for 87.4% of the initial yield.

Copelouzos Group plans to lay a submarine cable to link 9.5 GW of wind and solar power in Egypt to Greece’s Attica region. The project was recently included in the Entso-E 10-year development plan.
