Charge Transport Physics of Organic and Metal Halide Perovskite Semiconductors

Organic and metal halide perovskite semiconductors are soft functional materials that are emerging as a viable semiconductor technology in industries such as displays, electronics, renewable energy, sensing and healthcare. A key enabling factor has been significant scientific progress in improving the charge transport properties and carrier mobilities of these materials, which has been made possible by better understanding of the structure-property relationships and the underpinning charge transport physics. Here we aim to present a coherent review of how we understand the unique charge transport physics in these two classes of semiconductors and discuss similarities and differences. We are also interested in the use of these materials in thermoelectric devices and we will discuss approaches to their controlled doping and understanding of the relevant thermoelectric physics.
