ORGANIC-INORGANIC HOLE TRANSPORT BILAYER FOR CARBON ELECTRODE PEROVSKITE SOLAR CELLS AND CARBON ELECTRODE PEROVSKITE SOLAR CELLS WITH ORGANIC-INORGANIC HOLE TRANSPORT BILAYER
A solar cell is provided that comprises: a glass substrate or a plastic polymeric substrate; a first electrode disposed on the glass substrate or the plastic polymeric substrate, an electron transport layer disposed on the first electrode; a perovskite layer disposed on the electron transport layer; an organic-inorganic hole transport bilayer comprising an organic layer which is disposed on the perovskite layer and an inorganic layer which is disposed on the organic layer; and a second electrode disposed on the inorganic layer.
A lamp canister consisting of solar cells is able to convert photon emissions from the light bulb into photoelectrons. Photoelectrons can generate electricity which can be stored, and used later by the light bulb to generate light. Using Albert Einstein's theory of the photoelectric effect, we are able to use photoelectrons and electorng cycling to generate energy. A lamp canister that comprises solar cells that converts the photons emitted by the light bulb to electricity which is stored and then used by the light bulb to generate light again. --- Our invention is an apparatus and a method to transmit, receive and convert photons to electrons from two connected devices.
A method of stabilizing perovskite ink, comprising the steps of preparing a perovskite ink using one or more solvents and adding to the perovskite ink a sulfur or sulfur based compound that interacts with amine groups in the perovskite ink to inhibit amine-water proton exchange. A perovskite ink, comprising precursor salts dissolved in one or more solvents that when deposited as a thin film crystallize to form the perovskite structure with an 'ABX3' composition in which: 'A' is a monovalent cation being one or more of methylammonium (MA+) and formamidinium (FA+), 'B' is a divalent cation, and 'X' is a halogen being one or more of F-, I-, Br- and Cl-; an additive selected from the group consisting of sulfur and sulfur based compounds that interacts with amine groups in the perovskite ink to inhibit amine-water proton exchange.

A method of growing high length-to-width aspect ratio lead halide microwires via perovskite-induced local concentration gradient. The method involves preparing a solution comprising a perovskite, MABr and a lead halide, wherein the ratio of lead halide to MABr is off-stoichiometric with an excess of the lead halide with respect to MABr being a minimum of 2% and a maximum of 25%. The method involves drop-casting said solution onto a pre- treated hydrophilic substrate. The method involves leaving the substrate in an open-to-air but undisturbed atmosphere to evaporate over time. This causes the formation of perovskite crystals, which then equimolarly consume PbBr2 and MABr until MABr is depleted, creating a gradient in the PbBr2:MABr ratio. The nucleation of PbBr2 microwires occurs along the concentration gradient into a region of lower evaporation and perovskite concentration.
