2 Best student awards for PV-Lab at WCPEC-7

After the best poster award of Jan Haschke, PV-Lab members won another two awards at the WCPEC-7. Gizem Nogay and Florent Sahli won the best student paper awards in area 4: Silicon Photovoltaic Materials and Devices and area 3: Multijunction and Concentrator Technologies, respectively.

In her work, Gizem Nogay researches poly-Si contacts based on an ultra-thin silicon oxide layer for the next generation of silicon solar cells. In her contribution: "A simple Process Flow for Silicon Solar cells with Co-Annealing of Electron and Hole Selective Passivating Contacts", a high fill factor up to 84% and conversion efficiencies up to 22.4% were presented. A manuscript about these results is under review and will be soon linked here.

Florent Sahli works on perovskite/silicon tandem solar cells and has recently demonstrated a record efficiency of 25.2%. In his presentation: “Hybrid sequential deposition process for fully textured silicon/perovskite tandem solar cells”, he discussed the innovative processing approach that enables the deposition of high quality perovskite top cells directly on fully textured silicon bottom cells. In addition to being the first demonstration of a fully textured tandem, this approach yields a record efficiency. More information can be found in an article recently published in Nature Materials.
