Production parameter regulation system for reflective solder strip suitable for n-type heterojunction cell

Abstract

The present application relates to the technical field of photovoltaic cell module manufacturing, in particular to a reflective solder strip production parameter regulation system suitable for N-type heterojunction cells, which comprises a data acquisition module, a state modeling module, a target generation module, an optimization control module and an execution issuing module. The data acquisition module acquires real-time process data such as solder strip substrate temperature, plated layer thickness online measurement value, reflective layer coating speed and tension roller pressure. The state modeling module constructs a production state evolution model based on this, depicting the dynamic coupling relationship between multiple parameters. The target generation module matches the model output with the cell performance specifications to generate a production target vector. The optimization control module inputs the target vector and real-time data into an improved model predictive control algorithm, which introduces an interior point penalty function based on the model gradient to handle coupling constraints in rolling optimization, and outputs the solder strip substrate temperature, plated layer current, coating pump speed and tension setting value. The execution issuing module issues the setting value for execution.
