Problem solved
Perovskite solar module manufacturing requires P1/P2/P3 patterning of transparent electrode, charge transport, and perovskite layers with micron precision across large areas. Substrate thermal expansion and layer shrinkage during processing cause misalignment, reducing active area. NITTOKU KYOTO's patented (JP5329505) stretch-compensation and contour-following technology enables <20µm dead-zone patterning, maximizing module efficiency in roll-to-roll production.
Application contexts
- Roll-to-roll flexible perovskite solar module manufacturing
- Sheet-to-sheet rigid perovskite module patterning
- Thin-film silicon and CIGS solar module scribing
Technical principle
Laser patterning (P1: TCO removal, P2: active layer scribe, P3: back electrode isolation) using optimized ultrashort-pulse laser parameters. Proprietary correction algorithms: (1) stretch-compensation adjusts for substrate thermal expansion/contraction, (2) contour-following aligns subsequent patterning passes to previous scribed lines. Roll-to-roll material handling enables continuous production.
Typical use cases
- P1/P2/P3 patterning for flexible perovskite solar modules on roll-to-roll lines
- Dead-zone minimization for high-efficiency large-area perovskite modules
- Scribing thin-film solar cells for BIPV and curved-surface applications
