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.

Abrégé

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.
