6 FAQs about [Light pulse treatment of discarded solar panels]
Why do solar panels need a special recovery process?
In most studies of first- and second-generation solar cells, each panel type i.e. c-Si, CIGS and CdTe, require a unique process for the recovery of resource materials, which impedes standardization efforts, delays implementation and increases the costs .
How can photovoltaic technology reduce waste?
Generations of photovoltaic technologies, namely crystalline silicon, thin-film, and third-generation solar panels, share the goal of achieving waste reduction through useful strategies for recovery of secondary raw materials from obsolete panels.
How can photovoltaic solar cells be recycled?
Wei-Sheng Chen et al., reported the recycling of photovoltaic solar cells by leaching and extraction process. The silicon cell consisted of 90% of Si, 0.7% of Ag, and 9.3% of Al. 4 M nitric acid was used for the recovery of Si and 1 M hydrochloride acid was used for the recovery of Ag, Al.
How to recycle solar modules?
For recycling the spent solar modules, the mechanical recycling process is widely used. Mechanical and hydrometallurgical processing are the most common types of recycling processes. In this method, the spent PV modules are broken into small pieces of particle sizes of 4 to 5 mm. The PV module’s lamination is damaged in this process.
How to remove Eva resin from solar panels?
The heat treatment process can eliminate 99.97% of EVA resin from PV cells . For the spent solar panels, the glass will be put on the downward side and the back sheet on the upside. The material is heated at 480 °C at a rate of 15 °C/min. Here the heating condition is important to avoid the breaking of silicon wafers .
What solvent is used in a solar panel reprocessing process?
Among various solvents, toluene is widely used. The spent solar panel will be immersed in a toluene solvent for approximately 2days at 90 °C, and the tempered glass and PV cell will be separated from the swollen and dissolved EVA resin. The recovered tempered glass and swollen EVA resin will remain on the surface of the PV cell.
