Loading Dependent Electrical Properties of Hybrid Perovskite Composite Media

Hybrid organic-inorganic perovskites (HOIPs) have been previously compounded with hydrophobic polymers in order to improve the resilience of HOIPs in humid environments. In this study HOIP particles were synthesized and dispersed into a polymer solution. The weight loading of the HOIP phase in the composite was increased until an abrupt change in the electrical conduction was observed indicating a percolation threshold was approached. Additionally, the CH 3 NH 3 PbI 3 / polystyrene composite media was characterized to assess morphology and the effect it has on the observed electrical properties.
