Bismuth Doping

Band gap reduction down to 0.8 eV is observed in tin iodide-based hybrid perovskites as a result of bismuth doping. The band gap reduction originated because of lowering of the conduction band energies. In spite of the foreign metal doping, the number of carriers is not affected.

Solution Processable

For solution-processable tin iodide cubic perovskites, a small amount of indium doping reduced the conductivity without changing the band gap or the carrier concentration. We demonstrated another possibility of foreign metal doping in tin iodide cubic perovskites and displayed a design strategy for electronic devices using hybrid perovskites.

The upshift Δ of the level at the bottom of the conduction band (the LUMO) from the neutral N-electron crystal to the negative N + 1 system, and therefore the fundamental gap εLUMO(N + 1) − εHOMO(N) = I − A, can be calculated simply and cheaply from the response part of vxc.
