However, the majority of the silicon used in solar cells ends up in landfills due to the difficulty and cost of purifying waste silicon. This research presents a breakthrough in upcycling silicon from photovoltaic waste into thermoelectric materials, offering potential for a circular economy for photovoltaics and electronic waste.
The scientists said thermoelectric devices are very tolerant to defects and impurities, which makes them particularly suitable for recycled silicon, which is uneconomical to recycle due to its defect- and impurity-sensitive nature. Their new technique consists of p ulverizing polycrystalline silicon into powder and pelletizing it into ingots.
