In 2022, the global capacity generated by photovoltaics exceeded the 1,000 GW mark. This success clearly shows the development that can still be expected from PV technologies in the future. In Austria, the installed capacity already exceeded 2 GW in 2020 and continues to experience high growth rates. The amount of end-of-life (EoL) PV modules is still relatively small, but we should prepare for an increase in return rates in the coming years. What to do with end-of-life solar panels? How can they be recycled and – their components – sensibly reused?
The research project PVReValue is dedicated to these and related issues. Based on existing research results, the aim is to generate the scientific and technical foundations for a complete processing and recycling process for PV modules. In order to develop a holistic process to achieve a recycling rate of more than 95% by weight, the following steps are considered:
- Input characterization
- Compound separation
- Further processing
- Output characterization
- Recycling of the output fractions
On the one hand, the innovation content is the multi-stage separation process, which causes a pre-fractionation of the fractions to be further processed; on the other hand, in the complex combination of further processing methods for the recovered fractions. The high quality of the process starts with the input characterization, whereby modules can be selectively charged and output qualities can be modeled and adjusted accordingly. The research project PVReValue thus generates high-quality recyclable secondary raw materials in the sense of a functioning circular economy.
