Heterojunction cell production monitoring system and method

Abstract

The invention discloses a heterojunction cell production monitoring system and method, and relates to the technical field of solar cells, and the system comprises a production monitoring module, a production analysis module, a safety analysis module, an environment monitoring module and a cloud platform. The production analysis module is used for acquiring and analyzing monitoring data of a production field, intercepting operation image information of field workers to perform feature point extraction, and judging whether the operation of the field workers is standard or not; meanwhile, a behavior recognition algorithm is used for recognizing limb actions of field workers, and when the field workers do not operate in a standard or rule-breaking mode, an alarm is given in time to remind the field workers to correct in time, so that production monitoring is automatic, and the production efficiency is improved; and the safety analysis module is used for receiving the environment data collected by the environment monitoring module, inputting the environment data into a safety evaluation model to obtain a safety evaluation label, and then carrying out safety reminding on field staff according to the safety evaluation label, so that the production safety is improved.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a production monitoring system and method for heterojunction cells. Background technique [0002] Heterojunction solar cells are a high-efficiency solar cell production technology that combines amorphous silicon and crystalline silicon solar cells to complement each other. The heterojunction solar cell uses a-Si to form a PN junction, and the entire process can be completed at a low temperature below 200°C. Compared with the formation temperature (900°C) of the original thermal diffusion type crystalline solar cell, it greatly reduces the manufacturing process. Process temperature. Due to the characteristics of this symmetrical structure and low-temperature process, the deformation and thermal damage of the silicon wafer caused by heat or film formation are reduced, which is extremely beneficial to the realization of wafer thinning and high efficiency, and has industry-leadi...

Problems solved by technology

[0003] However, in the production process of heterojunction batteries, there is a lack of effective monitoring system. When the staff operate irregularly or make mistakes, they cannot be reminded in time, and it is impossible to understand the operation of the staff before and after the accident and its impact on the production of heterojunction batteries. Accurate information provides a reliable basis for technicians to analyze the cause of the accident; for this reason, we propose a production monitoring system and method for heterojunction cells
