Russia-based high-efficiency heterojunction solar module producer Hevel Group has started producing heterojunction solar cells using the M2+ (157.35 mm x 157.35 mm) n-type mono wafer, providing cell peak power up to 5.88Wp.
As a result of transitioning to the larger wafer size, Hevel said that its HJT power output was 330Wp for its 60-cell glass/backsheet modules and 390Wp for its glass/glass 72-cell modules.
The company also noted it had started testing M6 (166mm x 166mm) n-type mono wafer-based HJT solar cells that are designed for multi-busbar / multi-wire interconnection technology.
Hevel said that the 6%-larger-area M6 wafer-based cells were testing out at 6.71Wp. The M2-based cells were said to have maximum cell efficiency rates of 23.8%, while maintaining an average of 23.3%.
Recently, Hevel said it was set to expand solar cell and module assembly capacity to 340MW in 2020, up from 260MW.
Mar 10 - Mar 12, 2021
Penang, Malaysia (also available virtually)
Understand fully the technical and logistical supply chains that determine the production and performance of solar modules, including all related factors impacting quality, reliability & bankability. This event will be run as a live event in Penang for delegates able to attend and will also welcome virtual delegates via streamed content and online networking.
Oct 27 - Oct 29, 2020
Going into its fifth year over 200 delegates from 150 companies and 20 countries representing the PV supply chain will gather (virtually, due to COVID-19) for 3 days to discuss the technology roadmaps for PV cell advancement in GW markets. The scope of the event has been expanded this year, to cover developments in wafer supply and thin-film investments and technologies alongside all the regular benefits to all stakeholders tracking PV technology and investment trends for the next 5 years.
