| Abstract | 本发明涉及一种同质结钙钛矿光电探测器及其制备方法和用途，所述同质结钙钛矿光电探测器中包含相邻设置的N型钙钛矿薄膜和P型钙钛矿薄膜，位于所述N型钙钛矿薄膜背对所述P型钙钛矿薄膜的一侧依次设置的电子传输层和透明导电衬底，以及位于所述P型钙钛矿薄膜背对所述N型钙钛矿薄膜的一侧依次设置的空穴传输层和金属电极，本发明所述光电探测器基于同质结钙钛矿的优化，使得其内部形成内建电场，内建电场和外加电场方向相同，其共同作用，进而加强光生电子空穴对的分离和加速载流子输运，进而提高了光电探测器的外量子效率和响应速度。 |
| Other Abstract | The invention relates to a homojunction perovskite photoelectric detector and a preparation method and application thereof. The homojunction perovskite photoelectric detector comprises an N-type perovskite thin film and a P-type perovskite thin film which are arranged adjacently. W, wherein the an electron transport layer and the a transparent conductive substrate are sequentially arranged on oneside, back to the P-type perovskite thin film, of the N-type perovskite thin film; wherein, and a the hole transport layer and the a metal electrode are sequentially arranged on the side, back to theN-type perovskite thin film, of the P-type perovskite thin film. The photoelectric detector is based on optimization of homojunction perovskite, so that a built-in electric field is formed in the photoelectric detector, the built-in electric field and an external electric field are the same in direction and act together, separation of photo-induced electron hole pairs is enhanced, carrier transport is accelerated, and the external quantum efficiency and the response speed of the photoelectric detector are improved. |
