Technical Tour: GÜNAM Photovoltaic Pilot Production Line (GPVL)
The GPVL facility at ODTÜ-GÜNAM has an approximately 600 m² production area and a production capacity of 100 wafers per hour. It is capable of manufacturing industrial-size silicon solar cells, primarily of the PERC/PERT/PERL/IBC/TOPCON types.
With a team of more than 20 researchers, GPVL operates as a fully integrated pilot production line, covering the complete process from silicon wafer to finished solar cell.
Equipment Available in the Cell Production Line
- Fully automated wet benches for mono-wafer texturing and junction isolation
- Diffusion furnaces for full-area p-type and n-type doping
- Spatial Atomic Layer Deposition (ALD) system for Alumina (Al₂O₃) passivation of p-type silicon
- PECVD systems for dielectric coatings (SiₓNᵧ and SiOₓNᵧ) and LPCVD for a-Si growth
- Picosecond laser system for contact opening and material removal/cutting
- Fully automated screen-printing and firing system
- Ion implantation system for p-type and n-type doping of industrial-scale silicon wafers
- PVD system for metal evaporation
- Electroplating systems (Ni/Cu/Ag)
The GPVL building and infrastructure were established with the support of the Republic of Türkiye Strategy and Budget Directorate.
The GÜNAM Tour will take place on Wednesday afternoon. To attend the tour, an enrollment in advance is mandatory and possible during the conference registration.
