摘要： Polymer transport materials for application in perovskite solar cells capable of being tuned or manipulated to achieve desired properties, are provided herein. The present disclosure is directed to methods, systems, and compositions for achieving polymer transport materials (i.e., hole transport materials (HTMs)) with desirable properties such as solution processability, energy level tuning (i.e., adjusting), high thermal properties, tunable (i.e., adjustable) wettability, and perovskite defect passivation. In some aspects of the present disclosure, the synthesis of such HTMs may be implemented via relatively simple and inexpensive processes.

摘要： This invention relates to a method for producing films of semiconducting material based on the organic-inorganic metal-halide compounds with perovskite-like structure, which can be used as a light-absorbing layer in solar cells, including thin-film, flexible and tandem solar cells, as well as can be applied for optoelectronic devices, in particular, light emitting diodes. The method is comprising the following steps: (a) applying a layer of a precursor, (b) applying a layer of composite reagent, and (c) treatment of the applied layers by the reagent X2 wherein the composite reagent applied in the step b) contains a mixture of AX and X2 reagents, and the film obtained after the step b) contains the seeds of the phase with a perovskite-like structure; the reagent AX is a salt comprising cation A+ and anion X−, and the anion X− is a singly charged anion; the reagent X2 is a molecular halogen.
