Embodiment Construction

[0018] First, inspect the battery chip, turn on the laser scribing machine and computer system, call out and set the required scribing program, set the center point on the scribing platform according to the specifications of the battery chip to be cut, and position the laser knife at the center point , set the computer parameters. Put the battery chip to be cut back on the dicing platform. Start the cutting button to move the focus of the laser up and down. When most of the sparks emitted by the laser hit the battery chip go upwards, the focus is adjusted. Adjust the cutting current knob and stabilize the potentiometer to make the current reach the value required for cutting. At this time, the cut battery chips are still connected together, but they can just be broken by hand. After the dicing machine is set and adjusted, it will be cut according to the size and shape of the battery chips. Check and sort the scribed battery chips, turn on the sorting tester and calibrate the...

Abstract

The invention discloses a photovolt component and the manufacturing method and application thereof. And it comprises battery chips arranged on an epoxy plate. And its manufacturing method: cutting and stepping the battery chip; press-welding the welding rods on main grids of the battery chips and connecting the battery chips in series; placing the series battery chips on the epoxy plate, where the back sides of the battery chips are arranged upward and each covered with polyester film and vinyl acetate polymer glue film from the top down; placing the spliced photovolt component into a laminator while making the polyester side of the spliced photovolt component downward, setting pointers of three vacuum meters on the laminator all less than -0.07Mpa, the temperature at 130 deg.C-135 deg.C and vacuumizing time 4-5 mins and thus forming a photovolt component. And it can be applied to small solar products and resin glue photovolt components, uneasy to change color, age and corrode and having long service life.

Description

technical field [0001] The invention relates to a photovoltaic module, its manufacturing method and application. Background technique [0002] At present, the production process of photovoltaic modules includes the production process of photovoltaic modules packaged by tempered glass and TPT, and the production process of photovoltaic modules packaged by resin glue and epoxy board. [0003] 1. Glass photovoltaic module production process: confirm the chip current according to the maximum output power requirements of the photovoltaic module, and then determine the battery chip area, and then perform scribing. Classify the battery chips at a fixed voltage, select the appropriate tin-coated copper strip to lead out the positive and negative electrodes of the battery chip, connect a certain number of battery chips in series according to the requirements of the output voltage of the photovoltaic module, and follow the design of the solar panel Dimen...
