NGSE 6

The NGSE7 took place from December 6th through 8th 2022 as an online event that was co-organized by the National Renewable Energy Labs (NREL, US) together with the partners FAU, HI ERN, the Erlangen Graduate School of Excellence in Optical Technologies (SAOT) and the International Research Training Group “Energy Conversion Systems: From Materials to Devices” (IGK 2495). The NGSE6 program covered the areas
Fundamentals of Photovoltaics and Simulation
Organic Photovoltaics – Materials, Stability
Perovskites – Materials, Stability
Advanced Concepts, Processing & Upscaling, Applications
The list of invited speakers presented at the NGSE5:

Detailed-balance Limit and Fundamentals
Multiple Exciton Generation
Up and Down Conversion
Singlet Fission
Hot Electron Capture
Emerging Concepts

The program consisted of 4 tutorials (45 min + 5 min discussion) and 14 invited talks (25 min + 5 min discussion). NGSE6 also expanded to a Latin American context (NGSE-LatAm) by offering a special three-day program in Spanish language. NGSE-LatAm offered a solid tutorial program in the area of novel photovoltaic technologies in order to enhance, update and expand the academic training of a greater number of Latin and Hispanic students.
