III-V solar cells based on germanium substrates have been the incumbent technology for space photovoltaic power for many decades. What few people know, is that these solar cells were initially developed on GaAs wafers. Why was GaAs completely replaced by Ge? Why in this specific market? We will explore this technology shift and dive into the world of germanium, because next to multi-junction solar cells, many other applications might benefit from the same characteristics. The speaker will challenge the audience to envision new ideas and possibilities of germanium.
Pieter Arickx is Umicore’s Commercial Manager for Germanium products in Europe and Asia. In his role he is responsible for sales of Germanium products such as substrates and Germanium Tetrachloride. Next to this he also develops, organizes and purchases Germanium from recycling resources. Pieter holds an MSc degree in Materials Chemistry from Ghent University (Belgium). After a short research project at Ghent University, he joined Umicore where he first worked for 4 years in the R&D department of the Germanium substrates, before joining the commercial team.
