Stabilizing hybrid organometal halide perovskite films against moisture by using a sandwich structure approach
Using hybrid organometal halide perovskites as sensitizer in hybrid solar cells has attracted very high attention in the last two years due to the very high efficiencies which have been reached within this time. One of the remaining major challenges is the moisture sensitivity of the used perovskites, which seriously limits application in solar cells since under the influence of moisture the solar cells rapidly degrade (within minutes). Based on previous experiments at D22 (see report experiment 1-04-99) giving insights into moisture ingression, we realized a stabilization by using a sandwich structure that has a thin layer of 2D perovskite on top of a thick film of 3D perovskite. In the present investigation we want to gain deeper insights into this very promising stabilization mechanism. We want to follow the ingression of moisture into such sandwich architectures as function of the thickness of the protecting 2D perovskite top layer with in-situ grazing incidence small angle neutron scattering (GISANS). The thickness of the layer of 2D perovskite top layer will be varied.
