Taiwan’s largest battery comes online
United Renewable Energy has energized a 15 MW/15 MWh storage system connected to a 150 MW solar park located near Tainan.
Inverted perovskite solar cell achieves 22.31% efficiency via novel electron-accepting interlayer
A Korean research group has built an inverted perovskite cell that is able to retain 91.7% of its initial efficiency after 1,000 h under standard illumination conditions. They built the device with an electron-accepting interlayer that also acts as charge transport.
Floating solar for water pumping
A community in Spain is using a 1.6 MW floating PV array to power water pumps for irrigation purposes. Spanish specialist Isigenere provided its technology for the project.
Hydrogen to play limited role in building energy supply
How much hydrogen is actually needed? Several German research institutes have examined 40 energy scenarios for hydrogen ramp-up and found that 15 million GWh of hydrogen will be needed worldwide by 2050.
The Hydrogen Stream: Canadian startup unveils 120 kW fuel cell system
In other news, Alstom tested its hydrogen train for long-distance transportation and the IEA released a report suggesting that hydrogen development may require an annual investment of around $60-130 billion through 2030.
Q Energy France unveils pilot PV system for hydroponics
The prototype system covers an area of 250 m² and is equipped with a rainwater recovery system. Q Energy France and its partner Aquacosy are now looking for land for a larger project.
Pumped hydro storage for rivers, coastal lines
Scientists in Germany have developed a new methodology to identify suitable areas for pumped hydro storage projects close to rivers or shorelines. Their new method considers parameters such as the minimum required flat area for the reservoir, the allowable slope of the terrain, the minimum head, and minimum required head to distance ratio between two reservoirs.
Cadmium-free kesterite solar cell with 9.7% efficiency
Researchers in China developed a new kesterite solar cell they say has improved efficiency and stability. The device was able to retain around 90% of its initial efficiency after 100 days without encapsulation.
Longi achieves 26.12% efficiency for gallium-doped p-type heterojunction solar cell
The result, confirmed by Germany’s Institute for Solar Energy Research Hamelin (ISFH), was achieved on a heterojunction solar cell based on an M6 wafer.
Jinergy unveils all-black solar module series for rooftop PV
The all-black series includes a monofacial PERC module with an efficiency of up to 20.86% and an n-type heterojunction product with an efficiency of 21.68%. Both products feature all-black integrated design, with black backsheet, black busbar, black frame and black encapsulant material.
