Industrial Scale Production of High-Efficiency Perovskite-Silicon Tandem Solar Modules

energyPilotedTRL 6

Imagine adding a special high-performance layer on top of a standard silicon solar cell, like adding a turbocharger to an engine. This project creates a 'sandwich' of two different materials to capture more sunlight than current panels can. It moves this technology from a small lab experiment to a real factory line to make them in bulk.

The business problem

What needed solving

Standard silicon solar cells are reaching their physical efficiency limits, slowing the pace of energy transition. Europe lacks a domestic, high-volume production chain for next-generation high-efficiency PV modules.

The solution

What was built

A pilot production line in Germany and a set of manufacturing processes for perovskite-silicon tandem cells, including tested encapsulation materials for long-term stability.

Who can put this to work

Solar Manufacturing
enterprise
Target: PV Module Manufacturer

If you are a PV module manufacturer dealing with the efficiency limits of standard silicon cells — this project developed a pilot line that enables 26%-efficient modules on industrial scale. This allows you to produce higher-performance panels with a lower CO2 footprint.

Renewable Energy Infrastructure
enterprise
Target: Utility-scale Solar Farm Developer

If you are a solar farm developer dealing with limited land area for energy production — this project developed tandem cells that push efficiencies beyond the limit of Si. This means you can generate more power from the same amount of surface area.

Chemicals and Materials
SME
Target: Encapsulation Material Supplier

If you are a material supplier dealing with the degradation of solar cells in harsh weather — this project developed a screening of encapsulation materials to meet market expectations of over 30 years of stability.

Frequently asked

Quick answers

What is the expected cost or price advantage?

The project aims to provide the best ratio of performance over manufacturing costs to ensure a cost-effective solution for decarbonization. Based on available project data, specific price-per-watt figures are not provided.

Is this technology ready for industrial scale?

Yes, the project is establishing a pilot line in Thalheim, Germany, to demonstrate high-volume manufacturing processes. The goal is to enable GW-scale production in Europe by 2030.

How is the IP and licensing handled?

Based on available project data, specific licensing terms are not mentioned, but the project involves a consortium of 17 partners including 8 industry players and 6 SMEs to build a European innovation base.

What is the timeline for market entry?

The pilot line is expected to be set up by 2026, with a long-term vision of reaching GW-scale production by 2030.

How does this integrate with existing silicon PV lines?

The technology 'spices up' existing industrial Si cells by adding a thin perovskite top cell in a monolithic tandem device, leveraging existing silicon foundations.

Consortium

Who built it

The consortium is heavily weighted toward commercialization with a 47% industry ratio, comprising 8 industry partners (including 6 SMEs) and 17 total members across 12 countries. The presence of Q CELLS, one of the world's largest PV module manufacturers, as the coordinator ensures the research is directly aligned with industrial manufacturing requirements and market scalability.
