• Texturing & Saw Damage Removal
• Boron Diffusion / PSG Removal
• Tunnel Oxide & Poly‑Si Deposition (LPCVD / PECVD)
• Rear/Front Passivation (PECVD)
• Metallization (screen printing / firing)
• Laser patterning & edge isolation
• Monitor and control cell efficiency, yield, scrap, OEE, and throughput.
• Ensure adherence to defined process windows using SPC and control charts.

2. Production & Yield Support

• Provide shop‑floor process support during all shifts.
• Troubleshoot:
• Efficiency loss (Voc, Jsc, FF degradation)
• TOPCon‑specific defects (poly‑Si non‑uniformity, tunneling failures, contact resistance)
• Wafer breakage, printing defects, firing issues
• Work closely with Production and Equipment teams to minimize downtime and stabilize processes.

3. Quality & Documentation

• Monitor inline and offline quality metrics:
• EL imaging, IV curves, Rs/Rsh trends
• Yield maps and defect pareto analysis
• Support maintenance of:
• SOPs, WIs, Control Plans, PFMEA
• Ensure compliance with ISO 9001, ISO 14001, and EHS standards.

4. Continuous Improvement

• Drive and support yield & efficiency improvement projects (ppm reduction, bin upgrade).
• Participate in DOE, RCA, 8D, and FMEA activities.
• Identify opportunities for:
• Consumable cost reduction
• Energy optimization
• Automation and digital process monitoring

5. New Line / Technology Support

• Support process qualification (IQ/OQ/PQ) for new tools, materials, and recipes.
• Assist in pilot runs and production ramp‑up of TOPCon technology.
• Coordinate with R&D / Central Technology teams during technology transfer.

Qualifications

Education

• B.Tech / B.E. in Electronics, Chemical, Materials, Mechanical Engineering, or related discipline.

Experience

• 5–8 years experience in solar cell manufacturing (PERC / TOPCon preferred).
• Hands‑on exposure to diffusion, PECVD, LPCVD, metallization, or laser processes.

Skills

• Strong understanding of crystalline silicon solar cell physics.
• Working knowledge of SPC, DOE, RCA, 8D.
• Data analysis skills (Excel, Minitab preferred).
• Good communication and cross‑functional coordination skills.
