Energy transport is of paramount importance for the operation and design of semiconductor devices. Lead halide perovskites, an emerging semiconductor for optoelectronic applications, exhibits significant phenomena that can enhance or disrupt lateral energy transport, such as photon recycling and microscale heterogeneity. Understanding and quantifying these energy transport mechanisms is critical for scaling perovskite photovoltaic device areas. In this thesis, we explore how photon recycling affects energy transport both in the macro and microscale, and develop a framework to quantify carrier diffusion anisotropy and grain boundary effects in optical microscopy measurements. This work paves the way for understanding anisotropic energy transport in heterogeneous materials.
