Abstract: An organic photovoltaic device comprises a substrate, a reflector positioned over the substrate, a first electrode positioned over at least a first portion of the reflector, a polaritonic antenna layer positioned over a second portion of the reflector different from the first portion, electrically connected to the first electrode, and at least one unit reaction cell positioned over at least part of the first electrode, the at least one unit reaction cell comprising a heterojunction layer comprising a donor material and an acceptor material, positioned over the first electrode, and a second electrode positioned over the heterojunction, wherein the polaritonic antenna and the reflector are configured to convert incoming photonic energy to polaritons. A method of fabricating an organic photovoltaic device is also disclosed.

Abstract: The present invention belongs to the technical field of protein and genetic engineering, and specifically discloses use of an erythropoietin human hepatocyte receptor B4 as a target in screening and preparing a biological formulation or medicament for increasing sensitivity to insulin. Also disclosed is use of an erythropoietin human hepatocyte receptor B4 in preparing an insulin-sensitized mouse model. On the basis of insulin signal regulation, a protein EphB4 capable of interacting with an insulin receptor (InsR) is found. The protein can interact with InsR, and insulin stimulation can promote the interaction between the two, which provides a basis for insulin resistance in the case of hyperinsulinaemia. Over-expression of EphB4 can promote degradation of InsR. Inhibition of EphB4 can enhance the sensitivity to insulin and improve insulin resistance.
