Quasi two dimensional (2D) perovskite based solar cells

 

In this project we take advantageous of the possibility to tune the perovskite dimensionality using long organic cation which separate the MX6 layers of the perovskite.  Typically, the organic cation has low dielectric constant while the metal halide has higher dielectric constant. 

This family of materials permits tuning of optical and electrical properties by changing either the organic or the inorganic component, or their relative abundance. 

Recently our quasi 2D perovksite based solar cells achieved high efficiency and high open circuit voltage
