Organic hybrid solar cell with perovskite structured light absorbing material, and manufacturing method thereof

Abstract

The invention provides an organic hybrid solar cell with a perovskite structured light absorbing material, and a manufacturing method thereof. The organic hybrid solar cell comprises the following components successively: a conductive substrate, an electric hole transmission layer, an active layer, an electric hole barrier layer and a cathode. The active layer comprises a light absorbing material layer and an electronic receiving layer. The light absorbing material layer has a perovskite light absorbing material which is represented by a formula: CnH2n+1NH3XY3, wherein n is a positive integer in 1-9; and X is lead, tin or germanium; and Y is at least one selected from iodine, bromine and chlorine. The electronic receiving layer is provided with at least one fullerene or a derivative thereof. A planar hybrid heterogeneous joint surface is arranged between the light absorbing material layer and the electronic receiving layer. The light absorbing material layer has advantages of simple structure, easy manufacture and relatively low cost. Therefore batch production of flexible and all-solid-state organic hybrid solar cells is facilitated.

Description

technical field [0001] The invention relates to a solar cell and its manufacturing method, in particular to an organic hybrid solar cell and its manufacturing method through a light-absorbing material with a perovskite structure. Background technique [0002] In recent years, due to the massive consumption of fossil fuels, the development of various renewable energy sources (such as solar cells, fuel cells, and wind power) has gradually attracted attention. For example, organic polymer solar cell is a low-cost, easy-to-manufacture, flexible and portable renewable energy technology. Due to the continuous research and development and improvement of relevant researchers, organic high-molecular The practicality of molecular solar cells is gradually increasing, for example, they can be integrated with buildings or clothing, so organic polymer solar cells may even have the opportunity to replace the current solar cells using semiconductor substrates. [0003] For example, in an e...

Furthermore, since P3HT is an organic polymer, the process required for its organic synthesis, such as Grignard Metathesis, is usually relatively more complicated than the synthetic methods of inorganic compounds or small molecular organic compounds Therefore, the equipment cost and processing cost required for the synthesis of P3HT will be relatively high, which is not conducive to reducing the production and mass production of such organic polymer solar cells.
