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 , so the equipment cost and processing cost required for the synthesis of P3HT will be relatively high, which is not conducive to the production and mass production of such organic polymer solar cells

Embodiment Construction
[0049] In order to make the above content of the present invention more comprehensible, the preferred embodiments of the present invention will be described in detail below together with the accompanying drawings. Furthermore, the directional terms mentioned in the present invention are, for example, up, down, top, bottom, front, back, left, right, inside, outside, side, surrounding, central, horizontal, transverse, vertical, longitudinal, axial, The radial direction, the uppermost layer or the lowermost layer, etc. are only directions referring to the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. Furthermore, the organic polymers mentioned below mostly use English abbreviations to replace their full names. Since these organic polymers are not the main feature of the present invention and are all commercially available existing products, they will not be described in...

An organic hybrid solar cell with a perovskite structure light-absorbing material and its manufacturing method, the organic hybrid solar cell sequentially includes: a conductive substrate, a hole transport layer, an active layer, a hole blocking layer, and a negative electrode, the active The layer includes a light-absorbing material layer and an electron-accepting layer. The light-absorbing material layer has a perovskite light-absorbing material of the following representative formula: CnH2n+1NH3XY3, n is a positive integer from 1 to 9, X is lead, tin or germanium, and Y is At least one of iodine, bromine and chlorine. The electron-accepting layer then has at least one fullerene or a derivative thereof. There is a planar hybrid heterojunction between the light-absorbing material layer and the electron-accepting layer. The light-absorbing material layer has a simple structure, is easy to manufacture, and has low cost, so it is favorable for mass production of flexible and all-solid-state organic hybrid solar cells.
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 polymer solar cells have indeed become The practicability of 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 ...
