Recently, Talesun Photovoltaic announced that its PERC cell efficiency has surpassed 23.50%, reaching 23.56%. This result was independently verified and certified by the National Photovoltaic Industry Metrology and Testing Center of the Fujian Institute of Metrological Science. The 23.56% efficiency of Talesun PERC cells—along with their current–voltage and power–voltage characteristics under standard test conditions (STC)—was achieved through the company’s proprietary PERC 2.0 technology, which incorporates further refinements in key areas such as diffusion doping, interface passivation, and metal contact design. These advancements have significantly reduced the cell’s overall J0 and boosted the open-circuit voltage to 691 mV.

Talesun Photovoltaic’s 23.56% PERC cell: current–voltage and power–voltage characteristics under STC conditions.
This breakthrough in PERC cell efficiency is based on the company’s proprietary PERC 2.0 technology, which incorporates further optimizations and advancements in key processes such as diffusion doping, interface passivation, and metal contact, significantly reducing the cell’s overall Jsc. 0 , the open-circuit voltage was boosted to above 691 mV (see the figure above). This major breakthrough in PERC cell efficiency stems from Talesun Photovoltaic’s sustained investment in R&D. The team has demonstrated a bold spirit of innovation; despite the global impact of the COVID‑19 pandemic, the company and its international partners have maintained highly efficient collaboration and a relentless drive for excellence, continuously overcoming technical bottlenecks and steadily enhancing both the power conversion efficiency and product quality of PERC cells.
