Solar cells are treated with acid to dissolve the thin metallic layer covering the cells. Sunicon recycling technology is applied to monocrystalline, polycrystalline, and amorphous silicon cells. The process consists of two main steps: a thermal and an etching process.
Effective spectral utilization can be achieved by using a variety of methods, such as multiple junctions, intermediate band gaps, quantum dot spectral converters, luminescent down-shifting (LDS) layers, and up-conversion materials. Solar cell efficiency could be considerably increased by improving spectrum utilization.
Current recycling methods, such as chemical leaching and advanced thermal treatments, are being developed to handle these materials effectively. Furthermore, research into less toxic alternatives and closed-loop recycling processes will be essential to mitigate the environmental impact of these high-efficiency solar cells. 3.4.
The life cycle of solar cells, which contain various toxic elements like lead, gallium, indium, tellurium, and cadmium, suggests a specialized waste disassembly process for PV cells . Effective recycling methods are crucial, as they facilitate the separation of these materials at the end of a solar cell’s life cycle.
Raising consumer awareness is crucial to increasing the uptake and support of photovoltaic (PV) cell recycling initiatives as well as for the save collection of used lithium ion batteries. Educational campaigns targeting both the general public and specific consumer segments should be included.
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 .
