GoodWe’s new hybrid inverters have efficiency ratings of 98.0% and European efficiency ratings of 97.5 %. They are available in five versions, with power outputs ranging from 15 kW to 30 kW.
A team of international researchers has simplified the deposition of thin film layers in the commercial production of TOPCon solar cells. Via a tube-type industrial plasma-assisted atomic layer deposition (PEALD) technique, they were able to achieve a power conversion efficiency of 22.8% in a 60-cell, 613 W TOPCon module.
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.
Canadian Solar has suspended its plans to list shares in Shanghai, while polysilicon supplier GCL Tech has revealed plans to move from the Hong Kong Stock Exchange to either the Shanghai or Shenzhen stock exchange. Trina and Longi have both reported solid financial results for the first nine months of the year.
Chinese scientists have built a selenium solar cell with an alloyed selenium-tellurium absorber, which reportedly reduces interfacial defects. Under standard illumination conditions, the device has an efficiency of 1.85%.
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.
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.
The Chinese government has started talks with major companies about polysilicon costs and supplies. Datang has revealed the results of its latest 5.5 GW solar panel procurement tender, while Tongwei has announced its third-quarter financial results.
The Chinese Academy of Sciences has switched on a 100 MW compressed air energy storage system in China’s Hebei province. The facility can store more than 132 million kWh of electricity per year.
Chinese researchers have developed a new solar cell with a planar n-i-p structure and an indium tin oxide (ITO) substrate. It also has a tin(IV) oxide (SnO2) buffer layer, a perovskite layer, a hole transport layer (HTL), and a layer made of copper. It was able to retain around 92% of its initial efficiency after 1,000 hours.
