Future high-quality solar-cell technologies and solar plants will have to fulfil high demands. Apart from low costs, the quality and a long service life of the products will have an essential role to play. To this end, the Coating and Passivation team works on two important applications:
- Development of a process for plasma texturing the surface of silicon wafers with little surface damages and high light absorption: This plasma texturing should become seamlessly integrated into the current production processes and in the midterm replace Wet Bench 1.
- Development of a charge-carrier-induced passivation of efficiency-limiting defects in mono-crystalline and multi-crystalline silicon: The intention is to avoid the light-induced degradation of the solar cells.
In addition, the Coating and Passivation team is responsible for the Instruments Development Laboratory at the Fraunhofer CSP. We support interested partners in developing and marketing of processes and instruments and have experience in defining and realizing standards.
