Strong Focus on Technology Development
Constantly pioneering new products and technologies, our aim is to help the PV industry improve solar cell efficiency and manufacturing productivity. As part of our commitment to the latest process technologies, we are currently driving the trend from wet to dry processing. Building on our expertise in thin-film silicon solar, our dry processing technologies are enabling smarter crystalline silicon manufacturing processes.
To advance our efforts in this area, we also participate in several industry initiatives such as:
- PEPPER Project in thin-film PV, where we successfully implemented PECVD chamber cleaning using molecular fluorine and helped to drastically reduce cleaning time
- EuroPlas Project working with companies such as Meyer Burger, where molecular fluorine is being used for dry texturization of silicon wafers
We are also well-prepared for future technology transitions such as n-type cells, which use different materials. And we can supply all the gases necessary for the very promising technology of heterojunction, which can deliver very high efficiencies. From our development activities in thin-film PV and the display industry, we have gathered in-depth knowledge around the process and gas applications that are particularly suitable for heterojunction cell manufacturing.
Let us work with you to help reduce your costs, increase your productivity, and further improve cell efficiency..
