Embodiment 1

[0027] Using a flat-plate capacitively coupled discharge device, a stable oxygen plasma is generated to quickly oxidize the hole transport layer to realize the normal operation of the solar cell device:

[0028] (1) The device obtained in Comparative Example 1 step (4) is placed in figure 2 On the lower electrode of the shown parallel plate capacitively coupled discharge device (the upper part in the vacuum chamber is provided with an upper electrode with a hole, the lower part has a parallel lower electrode, and there is an oxygen inlet just above the upper electrode), the hole transport layer is on the bottom electrode. above, and then vacuum chamber pressure to 3Pa.

[0029] (2) Open the intake valve to feed oxygen, the flow rate is 10sccm, and the vacuum chamber pressure is 20Pa; turn on the radio frequency power supply (frequency is 13.56MHz), and form a uniform oxygen low-temperature plasma between the upper and lower electrodes, and adjust the discharge power to 10W. ...

Abstract

The invention discloses a method for rapid oxidation treatment of a hole transport layer of a perovskite solar cell, which belongs to the technical field of solar cells. Use a plasma generator to generate stable oxygen plasma, place the perovskite solar cell in the oxygen plasma region, and use the active groups in the oxygen plasma to react with the hole transport layer to quickly complete the function of the hole transport layer and control the reaction time. The method has the following advantages: the reaction process is fast, efficient, and precisely controllable, and the functionalization of the hole transport layer can be completed within a few seconds or more than ten seconds, and better device performance can be obtained. Compared with the traditional method of standing in a specific gas atmosphere, the method has simple process, good controllability and flexible scale, and is very suitable for future industrial production.

Description

technical field [0001] The invention belongs to the technical field of solar cells, and in particular relates to a method for treating perovskite solar cells with oxygen discharge low-temperature plasma to quickly realize the functionalization of the hole transport layer. Background technique [0002] Energy is the material basis of social development. At present, fossil energy such as coal, oil, and natural gas, which are widely used in human social and economic life, are non-renewable resources and are becoming increasingly exhausted. It is difficult to obtain supplements from nature in a short period of time. Energy is extremely important. Among many new energy technologies, solar power technology has attracted extensive attention from academia and industry due to its outstanding advantages such as wide distribution, inexhaustible sources, clean and pollution-free power generation process, and high compatibility with existing power technologies. [0003] After more than ...
