The Pilot Production Line
• The semi-automated Pilot Production Line has been installed @ Dyepower R&D
Center (Fonte Nuova, Rome)
• It allows the production of the basic A4 size modules and of the large area
strings/panels (made with A4 modules composition)
• The pilot line is design for an overall throughput of 10.000 Sqm/Year.
• Automation permits the repeatability of the production processes. This will solve
the critical aspects for the industrialization route.

The breaktrough in Hybrid Organic/inorganc solar cell is due to a «new»
material: Organometal trihalide perovskite
In two years Perovskite Solar Cells have improved from 9.7 % up to 20.4 % !
A similar progress has never been observer in photovoltaic technology

Conclusion
•
•
•
•
•
Most critical IEC 61646 tests (UV, HF, DH) have been successfully passed with DSC
modules produces on pilot line
Dye Solar cells are quite mature to enter into the market (BIPV and indoor).
Open issue: improve (stable) efficiency, stable Green/Blue dyes are still missing
Hybrid Perovskite materials are becoming very important for solution process
optoelectronics (results on Photodiodes are very promising)
We have demonstrated that such technology can be scale to module size
dimension
