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.
