Energy Loss Analysis of Two-Terminal Tandem PV Systems under Realistic Operating Conditions—Revealing the Importance of Fill Factor Gains

The tandem PV technology can potentially increase the efficiency of PV modules over 30%. To design efficient modules, a quantification of the different losses is important. Herein, a model for quantifying the energy loss mechanisms in PV systems under real-world operating conditions with a level of detail back to the components and their...
