Enhancing the optoelectronic performance of perovskite solar cells via a textured CH3NH3PbI3 morphology
Abstract
Perovskite-based solar cells are generally assembled as planar structures comprising a flat organoammonium metal halide perovskite layer, or mesoscopic structures employing a mesoporous metal-oxide scaffold into which the perovskite material is infiltrated. To present, little attention has been directed toward the texturing of the perovskite material itself. Herein, a textured CH3NH3PbI3 morphology formed through a thin mesoporous TiO2 seeding layer and a gas-assisted crystallization method is reported. The textured morphology comprises a multitiered nanostructure, which allows for significant improvements in the light harvesting and charge extraction performance of the solar cells. Due to these improvements, average short-circuit current densities for a batch of 28 devices are in excess of 22 mA cm−2, and the maximum recorded power conversion efficiency is 16.3%. The performance gains concomitant with this textured CH3NH3PbI3 morphology provide further insights into how control of the perovskite microstructure can be used to enhance the cell performance.
