Trina Solar announced that its State Key Laboratory (SKL) of PV Science and Technology (PVST) has set a new record of 25.04 percent total-area efficiency for a large-area (243.18 cm2) n-type mono-crystalline silicon (c-Si) Interdigitated Back Contact (IBC) solar cell, with open-circuit voltage up to 715.6 mV.
The result was independently certified by Japan Electric Safety and Environmental Technology Laboratory (JET).
The company claims that its IBC solar cell is the most complicated but with the highest cell efficiency for mass production c-Si solar cell in the market.
The record-breaking n-type mono-crystalline silicon solar cell was fabricated on a large-sized industrial phosphorous-doped Cz Silicon substrate with a low-cost industrial IBC process, featuring conventional tube doping technologies and fully screen-printed metallization.
As the largest photovoltaic modules supplier and the leading PV total solutions provider, Trina Solar aims to be a global leader of Energy Internet of Things.
The Trina Solar State Key Laboratory of PV Science and Technology is one of the first state key laboratories based in PV companies and accredited by the Chinese Ministry of Science and Technology. The laboratory so far has broken 18 world records in PV cell efficiency and module power output.
