Abstract

The invention relates to a device and method for preparing a transparent electrode film of a photovoltaic cell. The device comprises a control system, a metal evaporation source, a scanning sliding device, a light coding system, a laser coupling repair system and a reaction cavity used for transparent electrode film growth, wherein a quartz tray is arranged in the reaction cavity, a transparent substrate used for electrode preparation is placed on the quartz tray, the scanning sliding device is arranged on the upper portion of the reaction cavity, infrared femtosecond laser and visible laser are coupled on the same light path, a laser emitting head is installed on the scanning sliding device, the laser penetrates through a quartz window and the quartz tray to measure the transmittance of the transparent electrode film, and a visible light detector is arranged in the reaction cavity and feeds back a measurement result to the control system. In the preparation process of the transparent electrode, the transparent electrode film is scanned and repaired in real time through the laser coupling repair system to ensure the smoothness of the transparent electrode film, so that the transparent electrode film has excellent light permeability and conductivity at the same time.

Description

technical field [0001] The invention relates to the technical field of preparation of flexible transparent electrode materials, and more specifically relates to a preparation device and method for a transparent electrode film of a photovoltaic cell. Background technique [0002] As an emerging category in the field of solar cells, flexible photovoltaic cells have been widely concerned by research institutions and enterprises. At present, commercial photovoltaic cells are mostly hard flat monocrystalline silicon and glass-substrate thin-film cells using ITO electrodes. This kind of hard battery is fragile and inconvenient to transport and carry. It cannot be used in some special occasions. Flexible photovoltaic cells can overcome this problem. Its existing shortcomings and expand the application of photovoltaic cells, including the surface of spacecraft, aircraft, and buildings. The production process of flexible photovoltaic cells can adopt the roll-to-roll process and is e...
