2016-01-04 Kazakhstan: Integration of a New Approach for Greener Production of Silicon and Gaseous Monosilane with World-Best Practices in the Field of Solar Photovoltaics


 Integration of a New Approach for Greener Production of Silicon and Gaseous Monosilane with World-Best Practices in the Field of Solar Photovoltaics

Description of the project offered: 
The project objective is the development and testing of a new approach to greener manufacturing of high-efficiency solar cells and modules, highlighting the strength of European photovoltaic (PV) technologies for large-scale terrestrial photovoltaics.

Silicon is the second most abundant chemical element in the Earth crust (after oxygen) and rightly occupies around 90% of the world's PV market. Solar-grade silicon is produced by purifying metallurgical grade silicon, which in turn is typically obtained in a so-called carbothermic process, leading to the release of carbon oxides as harmful and greenhouse gases. This fact in itself questions how green the use of silicon solar cells and modules is for the sake of environment.

Our previous research on the study of processes occurring in silicon-containing alloys during their metallurgical treatment led to the development of technologies for production and purification of metallurgical-grade silicon and gaseous monosilane avoiding the release of greenhouse gases.

The project aims at integration of these solutions into the value chain of producing solar- and semiconductor-grade silicon, leading to monocrystalline ingots, wafers, high-efficiency heterojunction silicon solar cells and modules. Demonstration and following commercialization of technologies for vertically-integrated manufacturing of high-efficiency solar cells and modules creates an opportunity of environmentally clean electricity generation at low cost.

Our group has a comprehensive experimental basis for obtaining of upgraded-metallurgical grade silicon and fabrication of high-efficiency heterojunction silicon solar cells and modules, including wafer texturing, deposition of amorphous silicon and electrode layers and metallization. The efficiency of targeted solar cells exceeds 20%.
