Solar panels are increasingly based on silicon. Solar panels have a 25- to 30-year lifespan and tend to degrade with time. They also generate less electricity.If we don’t recycle our silicon waste, there will be 60 million tons of photovoltaic panels on Earth by 2050.
Stanislav EVLASSIN, senior research scientist, Skoltech Center for Design, Manufacturing, and Materials, (CDMM), led a group of researchers to demonstrate an easy, 100% efficient technique for converting silicon wafers in aqueous solution into nanoparticles. This discovery may lead to a more environmentally friendly method of recycling silicon without toxic chemicals.
The new conversion method is controlled and can control the nanoparticle size. These particles can then be used for medicine, optics or photonics.
You can convert old panels to nanoparticles by using hydrothermal reactions in an aqueous solution. This method has the benefit of being able to control the size of nanoparticles in the range 8-50 nm, without using a lot of expensive equipment.
The environmental impact of nanomaterials and pollutants can be measured using the Nanoparticle Tracking Analysis

In their experiment, the team tested three types of wafers made from silicon: N type (nitrogen-doped), phosphorus-doped and HR (high-resistance). Based on the density functional theory, their theoretical estimation proved that Si-H bond formation occurs on the surface HR plates without ammonia as a catalyst.
The reaction can also be accelerated by adding additives like boron, phosphorus or molecular defects to solar panels.
Alkoxides are used as precursors in the vast majority of bottom-up methods to synthesize nanoparticles. Contrary to this, our top-down method uses bulk silicon as a source. This creates many advantages, including simplicity, scalability and controllable particles sizes.
Bondareva said: “Temperature is the most important parameter that influences particle size distribution. We observed that increasing pH has a large impact on the particle formation rate. “This is why we use the ammonia which speeds up the reaction.”
We then decided to investigate how nanoparticles form in this process. In order to achieve this, we used an heterogeneous-nucleation model that had a small number of nucleation center distributed on top of the silicon.
The chemistry of silicon nanoparticles
Silicon nanoparticles, also known as SiNP, are metal-free quantum particles with customizable surfaces and sizes. Silicon nanoparticles contain pure nano-silica. The particle size range is less than 5 nm, which is a small particle. Nano-silicon Powder is considered to be a newer generation of optoelectronic semiconducting material, with a large bandgap. In addition, it’s a light-emitting material.
Silicon nanoparticles, as we know, are absorptive (abrasive) and mesoporous. They have many important applications, including in nanotechnology, drug delivery, and medicine. The unique photoluminescence of silicon nanoparticles and their physical properties have made them a popular choice for many applications in recent decades.
What uses are there for silicon nanoparticles
1. Raw material for organic silicon polymer materials that reacts with organic material.
2. Polysilicon is made by purifying metal silicon.
3. Metal surface treatment.
4. The lithium-ion battery can be significantly increased in capacity by using nano-carbon or graphite as the negative electrode.
