Comparing The Energy Yield of (III–V) Multi‐Junction Cells With Different Numbers Of Sub‐Cells

We examine the performance of III-V multi-junction solar cells with different numbers of cells under diverse spectral conditions. Using both a detailed balance model and a more realistic analytical charge-transport model, we simulate the energy harvesting properties of a range of cell designs with calculated spectra over 1 year. The spectra are generated using the SMARTS2 model with real atmospheric data for three locations with diverse spectral characteristics. The work underlines the importance of matching multi-junction solar cells to their target spectrum in order to maximize their energy harvest potential.
