Solar cell string repair

How does a solar cell work?

se above dotted line.The ribbons are applie on both sides ofthe solar cell, covering the silv r busbars. Flux is applied to he ribbons or the cell busbars. The solvent is then dried out. The solid flux melts du ing preheating, somewhat below the solder melting temperature. In its liquid, activated state, flux temp

What is a high speed MBB cell Stringer?

The Ultra high speed MBB cell stringer is capable of manufacturing up to 7200 pcs/h, with a Yield of string ≥97%. It is also expandable, allowing for string visual inspection, MES system docking , etc 7200 half-cell/hour and 10000half-cell/hour, compatible with 156-230mm half-cell, 210-230mm 1/3 or 1/4 cut, 120-200μm, 9-20BB cell.

How are solar cells interconnected?

on process.Automated cell interconnection on tabber-stringersSolar cells are interconnected t a string (Fig. 1) using flat copper wires coated with solder. These ribbons are approximately 120-180μm thick and 1.5-2.4mm wide. Two-busbar cells require higher crosssect ons to limit serial resistance losses than

Why should you choose Stringer machines?

Stringer machines built in our warehouse go through quality checks to ensure precision and consistent output you can rely on. Over the years, our machines have been known the world over, providing photovoltaic production solutions to well-known solar providers. The successful projects speak for our technical force and service capacity.

How can a ring detect a broken cell?

rings can detect broken cells or misaligned ribbons and cells. Backlight visual systems basically analyze contours and can detect cracks in the cell area only n the case of the aluminium screen-print layer being affected. Interconnection continuity and the correct polarity of cells in one string is checked using dark IV-measurement, whic

How confirmware's Stringer setup works?

ConfirmWare’s stringer setup uses IR soldering method,and the welding section is equipped with temperature control system to achieve closed-loop temperature control; Ensure consistent temperature in welding area to reduce risk of thermal shock, fracture and crack.
