VR SOP Training for Solar PV Cell Manufacturing

Stable yields from ingot to finished cell—step by step

PV cell lines demand clean handling and tight process control. Spark builds bespoke VR training that mirrors your crystal growth, wafering, texturing/etch, diffusion, passivation, metallisation and test—so operators practise the exact sequence safely.

Common issues we fix

• Clean handling: wafer breakage, contamination and ESD.
• Process windows: etch/diffusion times, temperatures and chemistry control.
• Metallisation: screen alignment, paste laydown and firing profiles.
• Yield protection: EL/IV/PL test discipline and binning accuracy.

How our custom build works

1. Capture SOPs & SPC: recipes, limits and acceptance criteria.
2. Create scenarios: etch/diffusion runs, line changeovers and defect recovery.
3. Coach in VR: prompts matched to your MES screens and checklists.
4. Measure: right-first-time, excursion trends and retraining needs.

Benefits

• Higher cell efficiency and fewer scrap wafers.
• Safer chemical handling and better ESD control.
• Clean, auditable training records.

Why Spark

Your tools, chemistries and QA gates—turned into simple, repeatable training.
