P1-P3 laser and mechanical patterning process for perovskite solar modules
Patterning process for transparent electrode, functional layers, and back electrode in perovskite solar modules, with laser or mechanical options depending on film properties.
Problem solved
Enables precise insulation and series interconnection in thin-film perovskite modules while minimizing dead-area width, which is critical to module efficiency and yield.
Application contexts
- Film-type perovskite solar cell module manufacturing
- Building-integrated perovskite PV pilot lines
- Flexible substrate perovskite R&D
Technical principle
Precise layer removal for P1 ITO transparent electrode, P2 hole-transport/perovskite/electron-transport stack, and P3 back electrode; laser or mechanical mode selectable by film characteristics; roll-to-roll conveyance option for flexible film/UTG substrates.
Typical use cases
- R&D and pilot-line patterning for perovskite modules
- Flexible-film perovskite cell series-interconnect patterning
- Small-lot process verification before volume transfer
