Due to their efficiency and durability, crystalline silicon wafers are by far the most common absorber material used in the production of solar cells and modules today.

These wafers are primarily made using either a directional solidification that produces large-grained multi-crystalline (mc-Si) wafers with a greater defect density (and therefore almost out of production) or a solar-optimised Czochralski (Cz) growing method that produces crystalline silicon with low defect density (c-Si).

Fostering equity and justice in climate policies – Societal Readiness Pilot

Closed

Code: 37256 | Identifier Code: HORIZON-CL5-2025-06-D1-06 | Programme name: 2939 | Sub-program: Climate, Energy and Mobility (Cluster 5)(2021-2027) | Start submission calls: 06/05/2025 | End submission calls: 24/09/2025

Climate change and the transition to a low-carbon and climate-resilient future raises complex issues of equity regarding the equitable sharing of benefits and burdens of mitigation and adaptation efforts.

These considerations are not only giving impetus to global climate negotiations, but are also increasingly emerging as a central issue for national policy, legal systems and society at large.

Justice is therefore becoming both a critical factor and a potential barrier to shaping ambitious climate action, underlining the need to prioritise research to promote equitable climate transitions within the EU and globally.
