Abstract
Description
Technical Field
[0001] This utility model relates to the field of baking oven technology, specifically a baking oven for solar cell printing screens. Background Technology
[0002] A solar cell, also known as a "solar chip" or "photovoltaic cell," is a thin-film photovoltaic semiconductor that directly generates electricity using sunlight. As long as it is exposed to light under certain illumination conditions, it can instantly output voltage and, in the presence of a circuit, generate current. A solar cell is a device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. Crystalline silicon solar cells, which operate on the photoelectric effect, are the mainstream, while thin-film solar cells, which operate on the photochemical effect, are still in their infancy. Printed screen printing plates are a crucial component of solar cells, making the baking oven for printing screens an indispensable step.
[0003] However, the baking ovens commonly available on the market have many drawbacks. Traditional baking ovens use a single heating method, resulting in uneven temperature distribution inside the oven. This causes differences in the drying degree of different areas of the printing screen, which seriously affects the quality of the printing screen and the performance of the solar cells.
