Intermediate-band solar cell presents a possible route to break the Shockley-Queisser limit but the fabrication has been difficult. Here Hosokawa et al. exhibit working cells at room temperature in solution processed quantum dot-perovskite system with carefully designed miscibility and energy levels.
