Problems solved by technology

After each layer is spin-coated, the existing detection method mainly relies on the experimenter to observe with the naked eye. Although this method is more convenient, its disadvantages are 1. The coating on some layers is almost colorless, and it needs to be inspected after spin-coating. According to the ambient light, adjust the battery sample to a specific viewing angle to clearly observe the coating
2. Part of the solar cell preparation needs to be completed in the glove box, and it is not easy to clearly observe the spin coating of the coating
3. Without the use of testing equipment, experimenters cannot judge the quality of battery samples and sort them by visually observing the uncoated parts

Abstract

The invention relates to a solar cell coating detection device and a control method. The solar cell coating detection device comprises a conveyor belt, a lifting type four-foot detection platform, a high-definition area-array camera, a set of high-intensity light source and a computer for image processing. A battery sample on the conveyor belt is conveyed to the position over the detection platform through the computer, the control module and the starting motor; the servo motor, the high-intensity light source and the camera are started through the computer and the control module to shoot the battery sample; graying processing, filtering processing and the like are conducted on the battery sample photo, and the two-dimensional pixel gray value histogram is converted into spin-coating area information on the surface of the battery sample by adopting a visual algorithm. The device can clearly detect the distribution condition of the solar cell coating, and has a good application prospect in the field of thin-film solar cells.

Description

technical field [0001] The invention relates to the field of novel solar cell preparation, in particular to a solar cell coating detection device and a control method. Background technique [0002] Thin-film solar cells are a new type of photovoltaic device in which a thin layer a few microns thick is applied to an inexpensive substrate to create a voltage; current conversion efficiencies of up to 13 percent are achieved. In the preparation process of thin-film batteries, the quality of spin-coating of each layer will directly or indirectly affect the performance of the battery. After each layer is spin-coated, the existing detection method mainly relies on the experimenter to observe with the naked eye. Although this method is more convenient, its disadvantages are 1. The coating on some layers is almost colorless, and it needs to be inspected after spin-coating. According to the ambient light, adjust the battery sample to a specific viewing angle to clearly observe the co...
