Efficiency limits of electronically-coupled upconverter and quantum ratchet solar cells using detailed balance
Emily Z. Zhang, Jacob J. Krich
The intermediate band solar cell (IBSC) and quantum ratchet solar cell (QRSC) have the potential to surpass the efficiency of standard single-junction solar cells by allowing sub-g…
