Outline of Final Research Achievements	Tandem solar cells show high power generation performance under standard test conditions, but the amount of power generated outdoors (energy performance) was not clearly evaluated. In this research, we investigated fundamentals to connect the power performance under standard test conditions in the laboratory with the amount of electricity generated outdoors and explored the analytical model to predict the energy performance of the emergent tandem solar cells currently under development. We investigated theory, computer simulation, and experimental approaches to develop a method to quantitatively calculate the amount of power generated by a new type of tandem solar cell.
