Mr. Xudong Chen presents the topic of “Improved Front Side Metallization for Silicon Solar Cells by Direct Printing” on June 24th, 2011. Abstract: This work presents a direct printing technology and enabling tool for front side metallization of any size silicon solar cell. The conductive grid lines were formed by a one-step non-contact approach at high speed using a modified standard screen printable paste. The line width is as small as 40μm and the line thickness is more than 30μm after firing, which gives an aspect ratio more than 0.75. The front shading area is significantly reduced, and a previous study of 55μm wide 30μm grid lines showed up to 0.5% absolute cell efficiency increase compared to the screen-printing process baseline. In depth, the impact of direct-printed high aspect ratio grid lines in terms of ISC, VOC, FF and other data were presented. Due to further reduction of grid line width, the pitch between each grid line increases, which affects the travel distance of the electrons excited by photons, and affects the fill factor and ultimately the efficiency of the cell. A preliminary study of printing finer grid lines with high aspect ratio showed improved fill factor and cell efficiency. In addition, the extended study further investigates this relationship. The paralleled printing setup is anticipated to print each cell in two seconds. Event: The 37th IEEE Photovoltaic Specialist Conference, June 19-24, 2011 at the Washington State Convention Center, Seattle, Washington. |

nScrypt was located at a booth and presents at the IMAPS 2011 Florida Chapter Symposium, Feb. 24, 2011, Orlando, Florida
Mr. Paul Deffenbaugh gives oral presentation in Technical Session Two. His topic: "A Printed-Electronics Flying Camera". Click image for video. The micro-electronics for the helicopter's onboard miniature camera and transmitter were printed using an nScrypt micro dispense pump machine. (requires Silverlight, Hi-Speed connection preferred).Abstract:Printed electronics is a new and fast-growing field with the potential to allow electronic devices to become more compact and more reliable. Printed electronics exist at the confluence of additive manufacturing and precision-dispensed conductors. To showcase the latest capabilities in this process a printed flying wireless camera has been successfully developed which is manufactured using stereo lithography and direct-write thick-film polymer silver ink. |

| June 20-25, 2010 | nScrypt presents a poster presentation at the IEEE 35th Photovoltaic Specialist Conference (PVSC) at the Hawaiian Convention
Center in Honolulu, Hawaii. The topic: “High Speed Non-Contact Printing for Solar Cell Front Side Metallization.“.
Abstract:This work presents a non-contact high speed printing technology for patterning high aspect ratio fine grid lines for the front side metallization of crystallized silicon solar cells. The approach of achieving fine line printing with high aspect ratio was obtained by combining focused work of both material and process together. A modified silver paste was directly patterned by a one-step process onto the silicon wafers without using a screen mask and the line width was as small as 50µm, while the height was around 30µm after firing. The preliminary study of these printed cells showed up to a 0.5% efficiency increase by effectively reducing the shading area while maintaining high grid line conductivity and low contact resistance.

| May 6-7, 2010 | Mr. C. Mike Newton and Dr. Ken Church are the general chair and technical chair for the IMAPS Advanced Technology Workshop and Tabletop
Exhibition on Printed Devices and Applications, at Doubletree Resort Orlando, Orlando, Florida. Mr. Xudong Chen presents
on May 6th. His topic: “MicroDispensing/Spraying for Printed Electronics.“.
Abstract:Printed electronics is described and mostly understood as an ink jetting process. Ink jetting will enable many applications in the Printed Electronics Industry; however, Ink Jetting has limitations with regard to material choices. These limitations are primarily induced given the nature of the viscosities required for ink jetting. Ink Jetting has demonstrated some fine line geometries and the ability to cover larger areas with multiple nozzles and this is valuable form many applications. The idea of expanding the material choices, shrinking the resolution and allowing large area coverage would also be enabling. Direct print micro dispensing brings this contribution. Traditional Micro Dispensing is slow and limited; however, nScrypt technology has demonstrated 15 micron resolution, viscosities ranging from 1 centipoise to more than 30 million centipoise and with MicroSpray attachments, it is feasible to spray large and small areas, including control and patterning, with higher viscosity materials up to 5,000 centipoise. This process is explained with specific demonstrations in the printed electronic regime. Event Link |
