Solar cells and modules

Our PV solutions focus on four areas covering the entire value chain, from individual solar cells up to tailored integrated applications for BIPV and AgriPV. Here are some examples of what we offer:

Solar cells: Incremental and disruptive upgrades to extend the power conversion efficiency curve of the current mainstream PERC technology

• Manufacturing processes and related device architectures for ‘passivated contacts’ technologies
• Next-generation perovskite-on-silicon tandem solar cells, whose performances outperform those of the classical single-junction solar cells
• Novel generation of passivated contacts technology based on tunneling oxide layers capped with silicon-based thin films annealed at high temperatures

BIPV solutions: Roof and façade-integrated PV elements fulfilling customers’ architectural, technical, and legal requirements

• Aesthetically pleasing, active energy-producing units that offer a return on investment
• PV façades as dynamic building envelopes and climate adaptive building shells

Contacting technologies: New metallization materials and advanced contacting concepts for individual solar cells and their implementation in full PV modules

• Decreases the PV modules’ cost by either reducing silver metallization laydown or full replacement by copper
• Reduces shadowing losses to boost PV modules’ conversion efficiency
• Provides novel interconnection approaches to simplify manufacturing
• Improves the reliability of PV modules with a life expectancy of 40+ years

Encapsulation materials: Tailored materials and the related compounding/extrusion techniques for a range of PV technologies

• Dedicated applications such as colored polymers, highly reliable EVA and PO-based materials
• Polymer foils with controlled rheology for high- and low-temperature processes
