New solar records take module efficiency and output to fresh highs

Chinese solar module maker Risen Energy has achieved yet another pair of records for its HJT Hyper-ion solar module series, hitting new highs for both power output and energy conversion efficiency.

Risen announced this week that its HJT Hyper-ion modules have notched up a maximum power of 741.456W and an efficiency level of 23.89%.

On efficiency, this bests Risen’s most recent record for this series of PV modules, set back in December of 2021 at a high of 23.65%.

This latest improvement in both maximum power and module efficiency is ascribed to technological innovations such as ultra-thin wafers, zero busbar technology, Hyper-link interconnection, and encapsulation material.

The Hyper-ion modules also feature a stable temperature coefficient and a high bifaciality of up to 85% ±10%, capable of maintaining its power output above 90% after 30 years of use.

“As the latest HJT product, Hyper-ion has the best combination of both improvement and reductions – high power and high power generation, high efficiency and reliability, low degradation and low temperature coefficient, low CFP and low LCOE,” said Even Liu, senior R&D director at Risen Energy.

“Risen Energy will continue to innovate and improve our products to promote the era of carbon neutrality.”

The Risen Energy Hyper-ion is backed by the company’s 100μm ultra-thin cell technology and low-temperature process, which delivers a carbon footprint value (CFP) lower than 400kg eq CO2/kWc, well below the market average.

The new module records were verified by German certification organisation TÜV SÜD.
