Calibration of Tandem Solar Cells and Modules
Tandem solar cells offer avenues to increase efficiency beyond the current state of the art for commercial photovoltaics. New absorbers and device structures including hybrids that combine different material classes such as III-V/Si or perovskite/Si are intensely researched. To guide the evolution of tandem solar cells towards commercialization, accurate measurements of performance are required. In this tutorial we will discuss how an accurate performance calibration for a tandem cell or module is done and present common measurement artifacts and methods to identify and avoid them.
