Abstract

Perovskite solar cells are one of the most actively studied next-generation solar cells. This is mainly because high power conversion efficiencies can be achieved even with simple solution-based fabrication processes. In addition, wide bandgap perovskite solar cells can be used as top sub-cells in multi-junction solar cells due to their easily tunable bandgap properties. On the other hand, colloidal quantum dots (CQDs), whose band gap depends on the quantum dot size, are one of the few options that are compatible with solution processes and can be employed as lower sub-cells. Here, we show the potential of both types for the construction of multi-junction solar cells. To this end, we constructed a wide bandgap perovskite solar cell that is ideal for monolithic 2-junction perovskite/GaAs solar cells. We also developed a colloidal quantum dot solar cell with infrared absorbing PbS CQDs and constructed a spectral splitting multi-junction solar cell as a proof of concept.
