Carbon-based perovskite solar cells (C-PSCs) have the advantages of low-cost and high-stability, but their photovoltaic performance is limited by severe defect-induced recombination low hole extraction efficiency. 1D proven to effectively passivate defects on surface, therefore reducing non-radiative loss. However, unsuitable energy level most renders an undesired downward band bending for 3D perovskite, resulting in a high barrier reduced Therefore, rational design selection perovskites as modifiers are essential balancing defect passivation extraction.

Lead-free perovskites are considered to be candidates for next-generation photodetectors, because of their excellent charge carrier transport properties and low toxicity. However, application in integrated circuits is hindered by inadequate performance size restrictions. To aim at the development lead-free perovskite-integrated optoelectronic devices, a CsAg2I3/silicon (CAI/Si) heterojunction presented this work using spatial confinement growth method, where in-plane CAI microbelts with high-quality single-crystal characteristics primarily dependent on concentration surrounding precursor solution. The fabricated photodetectors based CAI/Si heterojunctions exhibit broad-spectrum detection capability ultraviolet–visible–near-infrared (UV-vis-NIR) range. In addition, show good photoelectric performance, including maximum responsivity 48.5 mA/W detectivity 1.13 × 1011 Jones, respectively. Besides, have rapid response 6.5/224 μs air stability over 2 months. This contributes new idea design devices high integration density.
