A 3D hybrid nanowire/microcuboid optoelectronic electrode for maximised light harvesting in perovskite solar cells

Abstract

A high-performance optoelectronic device requires efficient light harvesting and management in the electrodes. In this work, we report the integration of antireflective anatase TiO2 nanowire (TNW) arrays and CH3NH3PbI3 microcuboid (CMC) film into a new bilayer architecture. The highly porous and well-interconnected anatase TNW arrays showcase antireflective properties for enhanced light transmittance and provide a largely accessible surface area for anchoring the perovskite light absorber. The thick and compact CMC film enables efficient light absorption. Thus, perovskite solar cells (PSCs) fabricated with a hybrid TNW/CMC optoelectronic electrode achieved an optimal power conversion efficiency (PCE) of up to 20.1% under one sun illumination with a high Jsc of 23.2 mA cm−2, which can be attributed to the maximised light harvesting efficiency within the devices.
