Pioneering a low-cost & eco-friendly solar cell 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.
