Research & Development
As the name suggests, JPM Silicon is all about silicon. To be more precise, silicon for solar cells and thus green solar power. Based on a new process for obtaining silicon, we now cover the entire recycling cycle of silicon-based solar modules. From second-life solutions for disused solar modules, the subsequent recycling of the solar modules, to the recycling of the silicon. Research and development are therefore part of our DNA, so that we are active in various research projects together with partners.

Quartz & Carbon
Quartz (SiO2) and carbon are the raw materials for silicon production. Together with partners, we are developing a unique raw material test in order to increase resource and energy efficiency.
Today, silicon is extracted from quartz and coal in electric arc furnaces. We are researching new, energy-efficient production processes and the use renewable raw materials.
Metallurgical silicon is purified in technically and energetically complex processes to produce silicon with a purity of at least 99.99999%. The silicon usually obtained via the so-called Siemens process is also known as polysilicon.
Only a perfect crystal structure makes it possible to generate electricity from solar cells. Silicon is therefore processed into blocks or single crystals.
Currently our focus is on the recycling of the sawing waste, whereby we continuously develop our technologies.
Doped accordingly and fitted with contacts, the wafer becomes a solar cell. Here we are researching new manufacturing processes for the production of solar cells on the moon.
In addition to silicon, solar modules contain a large number of valuable raw materials such as glass, plastics, metals and precious metals. With our spin off SOLAR MATERIALS and together with the IWF of the TU Braunschweig we are developing a unique recycling process.
Solar power ultimately drives electric cars or is used to produce green hydrogen in industry. Here, too, we are developing efficient technologies with our partners.
