New nickel-based hybrid organic/inorganic metal halide for photovoltaic applications.

In this work, we have synthesized and fabricated solar cells with the hybrid metal halide compounds with the general formula ABX, where the A cation is methylammonium, the B cation is nickel, and the X anion is chlorine or a mixture of chlorine and iodine. We obtained experimental evidence that this material is a semiconductor with an orthorhombic crystalline structure which pertains to the space group Cmcm. The bandgap can be modulated from 1.
