Innovative structuring concepts for next-generation solar cells
During the project duration of StrukturSolar I (2012 - 2015) and StrukturSolar II (2015 - 2020), research questions in the field of structuring methods for solar cells were and are being addressed in several sub-projects. The focus is on research work by young scientists who want to gain further qualifications with their research through a doctorate and are jointly supervised by both cooperating universities: Anhalt University of Applied Sciences and Martin Luther University Halle-Wittenberg (MLU).
