Why Standard Sensors Fail in PV Manufacturing

Harsh PECVD and diffusion environments destroy cheap sensors – costing more in downtime than the initial savings

Extreme Temperatures
PECVD runs at 200-400°C, diffusion furnaces at 800-1000°C. Standard sensors degrade within 3-6 months.
Corrosive Gases
SiH₄, NH₃, N₂O, POCl₃ attack sensor surfaces. Only Inconel and special alloys survive long-term.
Sensor Drift
±5% drift means ±0.5% cell efficiency loss. At scale, that's crores in revenue gone.
Downtime Costs
Each hour of PECVD downtime = ₹5-10 Lakhs lost. Cheap sensors need replacement every 3-6 months.

The Inconel Advantage

Our ThermoAir sensors use Inconel housing – a nickel-chromium superalloy originally developed for jet engines and nuclear reactors. Where standard stainless steel fails in months, Inconel survives for years in corrosive PECVD and high-temperature diffusion environments.

Result: 4-8× longer sensor life, dramatically reduced downtime, and consistent ±0.5% of reading accuracy that translates directly to higher cell efficiency.
