The ideal recyclable solar cell: Comment in Nature Reviews Chemistry

4. July 2025

Solar cells should be efficient, stable, and cost-effective. However, recycling is usually neglected. However, given the increasing number of discarded modules and limited raw materials, this is becoming an issue.

In their recently published commentary in Nature Reviews Chemistry, authors Dr. Ian Marius Peters and Prof. Christoph Brabec call for a radical redesign. They identify three central obstacles: strong material bonds, complex layer architectures, and chemical mixing make it difficult to recover valuable materials. Additionally, many design features that promote efficiency conflict with good recyclability.

The key finding is that there is no perfect material that meets all requirements simultaneously. Future solar cells must therefore be designed as a compromise between performance, durability, and recyclability. The development of new photovoltaic technologies offers an opportunity to consider recyclability from the beginning, promoting a sustainable, circular solar energy economy.
