Michael Ehinger, VP – Trumpf Huettinger | Topic: Cost Reduction of PV-Cells Driven by Power Supplies in Combination With IoT
TRUMPF Huettinger is serving PV-Cell tool makers with PECVD power supplies for depositing best in class a-Si / AlOx / SiN / TCO layers. These are one of the most critical components having an influence on the future cost reduction for PV Cells.
The efficiency of the PV-Cell is THE key where every 0.1 % counts. The precision and quality of deposited layer is imperative for maximizing the efficiency of a PV-cell.
The cost for manufacturing equipment was also going through the Scale of economy. To continue this trend, a paradigm change for PECVD power supplies is needed. Multi-Output power supplies are promising product architectures.
Throughput is very much dependent on Tool uptime, Yield, deposition rate and quality. PECVD power supply quality grants highest possible uptime, effective ARC Management leads to a high cell yield and the deposition rate defines the speed.
IoT services are an additional option to improve these Key Performance Indicators.
