MicroScreen is a leader and innovator in screen technology for solar cell production. We utilize the most advanced laser systems available and very fine tungsten mesh, woven with wires just 13 microns in diameter, to create long-lasting screens that are capable of printing extremely tiny features with high accuracy.
Throughout the last 30 years, flatbed screen printing has established itself as the predominant metallization process for the mass production of silicon solar cells. This paper presents a comprehensive overview on printing technologies for metallization of solar cells, with Sebastian Tepner and Andreas Lorenz contributing equally to this work.
The technology faces more and more challenging throughput requirements for the upcoming years. The economic success story of the past is not a guarantee for a bright future, especially for flatbed screen printing as the predominant metallization process for PV.
When the cell is cofired (in the next production step), the paste etches through the silicon nitride and silver contacts the underlying silicon to form the n -type contacts to the solar cell. This tutorial focuses on the silver screen printing process as the design of the screens is critical for the way the pattern is used to form the metal grid.
The Silver Screen Printing process depends on properties of the screen (mesh density, strand diameter, emulsion thicknesses above and under the screen, finger width and pitch), the paste viscosity as well as the printing process (squeegee pressure and speed).
Furthermore, a detailed analysis on manufacturing tolerances is given, showing that the 26.565° screen angle offers the best compromise between challenges during manufacturing and potential performance in production of Si-solar cells. Flatbed screen printing is the dominating process in industry for metallization of silicon solar cells.
Several research groups presented promising results of feasibility studies using flexographic printing, rotary screen printing, and gravure printing for solar cell metallization.

Screen Printing Primer En - Free download as PDF File (.pdf), Text File (.txt) or read online for free. Screen printing is a key process for producing crystalline silicon solar cells. It involves using a screen with openings to print very fine conductive lines on the front and back of wafers. This forms the circuitry to conduct electrons within the cell.
The current work demonstrates the successful metallization of a PERC silicon solar cell with screen-printable copper (Cu) paste that is sintered at elevated temperature in air atmosphere. The existing state of the art in Silicon (Si) solar cell metallization is silver (Ag) paste; Cu cost is 1/100th the cost of Ag and has a comparable conductivity. However, Cu undergoes …
