Invitation and abstract [PDF]
Realization of highly performing vertically built opto-electronic devices typically requires a close control over the thickness of the constituing layers in order to find the balance between the conformity and optical and electronic properties of the layers. Specifically in solar cells, charge selective layers should be thick enough to allow pinhole free coverage and thin enough to minimize the electrical series resistance and the parasitic absorption. In the talk I will first present recently developed applications of thin organic and inorganic layers in perovskite solar cells which provide conformal coverage and minimization of material consumption while retaining selectivity of the charge transport over nanometric distances. Furthermore I will briefly describe how the 2D nature of PbI2 can be exploited for environmentally friendly synthesis of MAPbI3 submicron sized particles and how the surface modification of chemically exfoliated MoS2 can promote its homogeneous incorporation into elastomers.
