Additive engineering for Sb₂S₃ indoor photovoltaics with efficiency exceeding 17.

ABSTRACT: Indoor photovoltaics (IPVs) have attracted increasing attention for sustainably powering Internet of Things (IoT) electronics. Sb₂S₃ is a promising IPV candidate material with a bandgap of ~1.75 eV, which is near the optimal value for indoor energy harvesting. However, the performance of Sb₂S₃ solar cells is limited by nonradiative recombination, which is dependent on the quality of the absorber films. Additive engineering is an effective strategy to fine tune the properties of solution-processed films. This work shows that the addition of monoethanolamine (MEA) into the precursor solution allows the nucleation and growth of Sb₂S₃ films to be controlled, enabling the deposition of high-quality Sb₂S₃ abs
