DM-CAP-4704S: A New Carbon Paste for Perovskite Solar Cells
Dycotec Launches DM-CAP-4704S Carbon Paste for Perovskite Solar Cell Manufacturing
Dycotec Materials is pleased to announce the commercial release of DM-CAP-4704S, a carbon conductive paste specifically developed for use as a carbon electrode material in perovskite solar cell manufacturing.
Perovskite photovoltaic technology has attracted significant attention in recent years due to its potential to deliver high-efficiency solar energy conversion using low-cost manufacturing processes. However, the development of commercially viable electrode materials remains a critical challenge for large-scale production.
Carbon electrodes offer an attractive alternative to precious metal-based contacts, providing the potential for reduced material costs, simplified manufacturing, and improved long-term stability. Achieving these benefits in a production environment requires careful optimisation of both material properties and processing characteristics.
Addressing Key Manufacturing Challenges
The development of carbon electrode materials for perovskite devices presents a unique combination of technical and manufacturing requirements, including:
-
- Solvent compatibility with perovskite layers
- Strong adhesion to TCO-coated substrates while maintaining low contact resistance
- Dense, pinhole-free layer formation with low sheet resistance
- Optimised work function alignment to support efficient charge transfer
- Mechanical flexibility for compatibility with roll-to-roll (R2R), flatbed screen printing, and blade coating processes
- Long screen residence times combined with rapid low-temperature curing (<100°C)
- Compatibility with encapsulation systems
- Demonstrated durability under thermal shock, thermal cycling, and environmental lifetime testing
Following several years of development, DM-CAP-4704S has been engineered to address these requirements while supporting scalable manufacturing processes.
Proven Performance in Commercial and Research Environments
DM-CAP-4704S has been successfully evaluated by our partners. The material has demonstrated compatibility with high-volume roll-to-roll and flatbed screen printing processes, enabling straightforward integration into existing manufacturing workflows.
Devices produced using the material have achieved efficiencies exceeding 20%, while also demonstrating strong long-term durability performance. The paste system is designed for rapid curing at temperatures below 100°C, helping reduce energy consumption and supporting high-throughput production.
Available for Commercial Evaluation
DM-CAP-4704S is now available in production quantities with commercially scalable pricing.
Researchers and manufacturers interested in evaluating DM-CAP-4704S for perovskite photovoltaic applications are encouraged to contact Dycotec's technical team to discuss their specific requirements.
