The new HDT module was unveiled at Intersolar Europe on Wednesday.
Risen Energy launched its Heterojunction Double-sided Technology module at Intersolar Europe and immediately called for collective efforts to drive down its cost.
Risen is eyeing cell efficiencies in excess of 23% and a further 10-30% of yield from the rearside. Development work for a 2.5GW manufacturing facility in Ninghai City is already underway.
“We’ve selected a site but we still need more time for the selection of the tools for the production line. These are under assessment,” Danny Song, senior manager of product management at Risen told PV Tech.
“The cost needs to decrease before this can be a mainstream module. The tools and reducing silver usage, as well as some other materials, have scope for reducing cost,” added Song.
The modules use N-type mono wafers, half-cut cells and a combination of silicon and amorphous silicon. According to Risen, performance in high-temperature environments is improved by 6-9%.
With the cost of the modules at the higher end of the scale, Song expects HDT modules to enter very specific markets in its early stages.
“The rooftop markets in Australia, Europe and Japan will be the initial target markets. This is where we will focus in the beginning.
“By 2021 I think HJT modules will be more competitive and very familiar technology. You have to take a long-term view on trends like this. Yes there might be a risk but you have to commit early to a new technology or will miss out,” he said.
The first ever event dedicated specifically to solar PV Heterojunction manufacturing and multi-GW production challenges and opportunities. Meet the global community driving Heterojunction to multi-GW status in mass production today in the spectacular setting of St. Petersburg in Russia.
Going into its fifth year over 200 delegates from 150 companies and 20 countries representing the PV supply chain will gather in Malaysia 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.
