SPI Energy’s PV manufacturing subsidiary Solar4America has said that it will start manufacturing heterojunction technology (HJT) n-type solar cells in the US by the end of 2024.

The company is headquartered in California, where it currently produces passivated emitter and rear contact (PERC) modules for rooftop and utility-scale deployments, the capacity of which is expected to reach 2.4GW by the end of 2023.

PV Tech has contacted SPI Solar to inquire about the capacity of the new cell production facility, and the location has yet to be determined.

Denton Peng, chairman and CEO of SPI Energy, said: “We are excited about this significant step in our strategic expansion. The production of HJT solar cells aligns with our commitment to providing cutting-edge renewable energy technology while reducing carbon footprints globally.”

Using multiple silicon-based layers atop an n-type silicon substrate, HJT cells offer higher conversion rates than tradition p-type cells. The solar industry as a whole is transitioning from PERC – which has been the norm for solar cell technology for decades – into HJT and tunnel oxide passicated contact (TOPCon) cell technologies.

Solar manufacturer JA Solar spoke with PV Tech at the SNEC conference earlier this year about the ongoing n-type ‘transition period’.

The US has been attempting to double down on PV manufacturing in its Inflation Reduction Act (IRA); the announcement of cell capacity from SPI – though most likely fairly small scale – will be what is needed to fully establish a foothold in PV manufacturing for the US.

PV Tech has been running PV ModuleTech Conferences since 2017. PV ModuleTech USA, on 16-17 June 2026, will be our fifth PV ModulelTech conference dedicated to the U.S. utility scale solar sector. The event will gather the key stakeholders from solar developers, solar asset owners and investors, PV manufacturing, policy-making and and all interested downstream channels and third-party entities. The goal is simple: to map out the PV module supply channels to the U.S. out to 2027 and beyond.
