TOPCON Technology

TOPCON Technology becomes mainstream​Mass production efficiency:

Mass production efficiency is expected to reach 25% -26% in 2025, with high compatibility with existing PERC production lines, becoming the first choice for photovoltaic cell upgrades.​

Cost advantages: The amount of silver slurry is reduced by more than 30%, and the superposition equipment is localized (such as PECVD technology breakthrough), and the single watt cost is further reduced by 10% -15% compared with PERC.​

Application scenario: Large ground power stations and industrial and commercial rooftop projects are the main ones, and high-radiation areas are particularly prominent.

Heterojunction (HJT) Technology

Heterojunction (HJT) technology accelerates penetration​

Efficiency breakthrough: laboratory efficiency breakthrough 27%, mass production efficiency close to 26%, low temperature process suitable for thin silicon wafer (thickness < 120μm), reduce silicon material consumption.​

The cost reduction path: The investment cost of equipment fell by 40% (the popularity of domestically produced equipment), and the silver pulp alternative (copper plating technology) entered the production stage, driving the share of HJT in the high-end distributed market (such as household PV).
