Equipment Overview
The equipment irradiates the cell surface with high-energy laser to excite carriers and generate localized high-density current, which triggers interdiffusion between the metal grid lines and the silicon substrate, forming excellent ohmic contact and effectively reducing contact resistance. Meanwhile, it avoids large-area damage to the passivation layer, thereby improving open-circuit voltage and short-circuit current, and significantly enhancing the conversion efficiency of the solar cell.
Highlights
• Self-developed UW laser with specialized optics; adjustable spot size and energy distribution.
• High-speed galvo + high-speed DD motor; cycle time ≤ 0.75s, meeting screen-printing line speed requirements.
• Flexible linear loading/unloading module; fast and low breakage.
• Supports offline/online modes; offline loading and online emergency unloading run independently; large capacity and easy to use.
• Custom imported probe array and high-conductivity stage; long life, high performance, low breakage.
• 0BB compatible; optimized area-scan process improves efficiency by 0.05% vs. Line-scan.
