Pioneering a low-cost & eco-friendly solar cell technology
A novel lean process chain for the next generation of silicon heterojunction solar cells for TW-scale production.
SiLEAN Project introduction
The SiLEAN solution aims to achieve a record solar cell efficiency using a fully sustainable, In-, Ag-, and Bi-free technology.
The SiLEAN project aims to advance silicon heterojunction solar cell technology by introducing several innovative approaches. These include growing wafers directly from the gas phase at low temperatures, utilizing alternative passivation techniques for higher optical transparency, and developing indium-free contact layers along with silver and bismuth-free metallization for streamlined cell interconnection and encapsulation. All processes are designed for scalability to larger sizes and high manufacturing throughput.
