Due to their unique optoelectronic properties and potential for high efficiency, quantum dot (QD) solar cells and photodetectors have gained tremendous attention. Achieving efficient charge transport and extraction in these devices is crucial for enhancing their performance. Polymer interlayers play a vital role in facilitating charge transport and improving the device stability. This Spotlight on Applications paper focuses on the effective strategies employed to tune the microstructure of polymer interlayers in QD solar cells and photodetectors to achieve high efficiency by bringing together the recent literature. With the use of advanced synchrotron radiation scattering and microscopic characterizations, we elucidate the impact of polymer properties, casting solvents, and physical blending methods on the microstructures of polymer interlayers in quantum dot solar cells and photodetectors. Furthermore, we take a detailed look at some facile strategies such as aggregation-suppressed blending and polymer synergy that have enabled precise control over the microstructure of polymer interlayers. Finally, we provide perspectives on future research directions and obstacles in the field.
