Patent number: 8993373Abstract: Methods of doping a solar cell, particularly a point contact solar cell, are disclosed. One surface of a solar cell may require portions to be n-doped, while other portions are p-doped. At least one lithography step can be eliminated by the use of a blanket doping of species having one conductivity and a patterned counterdoping process of species having the opposite conductivity. The areas doped during the patterned implant receive a sufficient dose so as to completely reverse the effect of the blanket doping and achieve a conductivity that is opposite the blanket doping. In some embodiments, counterdoped lines are also used to reduce lateral series resistance of the majority carriers.Type: GrantFiled: May 4, 2012Date of Patent: March 31, 2015Assignee: Varian Semiconductor Equipment Associates, Inc.Inventors: Nicholas Bateman, John Graff

Publication number: 20140379814Abstract: A system provides for the efficient delivery of messages from one or more message originators to one or more message recipients via a plurality of communication or messaging platforms. A message originator can create a single message and specify one or more message recipients, multiple communication platforms and delivery scheduling, all from a graphical user interface on a mobile communication device or a computer. The message will be formatted for the selected message recipients, the available and desired communication platforms in the desired priority order, and scheduled for delivery to the message recipients at selected time(s). Additionally, messages may be screened to reduce or eliminate potentially duplicate messages via one or more duplication filters. On the message recipient side, each message recipient can specify the desired communication platform and preference priority for receipt of messages, along with the desired timing for delivery of messages from each potential message originator.Type: ApplicationFiled: June 21, 2013Publication date: December 25, 2014Inventors: John Graff, Bruce Hassler, Dane Dellenbach, Jacob Hutchings, Daniel B.

Publication number: 20140216537Abstract: Several embodiments of a metallization process are disclosed, which achieve lower contact resistance and higher conductivity than methods currently employed with solar cells. These parameters result in a solar cell having improved performance and efficiency. In one embodiment, two different metals are used to create the metallization layer, where the first metal is selected for superior ohmic contact to the substrate and the second metal is selected based on conductivity. In a second embodiment, a first metal is evaporated or sputtered on the substrate. A second metal is then screen printed on the substrate. A removal step, such as etching is then performed to remove unwanted metal from the substrate.Type: ApplicationFiled: February 7, 2013Publication date: August 7, 2014Applicant: VARIAN SEMICONDUCTOR EQUIPMENT ASSOCIATES, INC.Inventor: John Graff

Publication number: 20140164909Abstract: A system and method for optimizing mobile communications with one or more message recipients is disclosed. The system is configured to create a unique URL and send it to a message recipient via an appropriate communication platform. The system waits for the unique URL to be requested and logs information from the web browser associated with the mobile communication device used to access the unique URL. The system may use this information to direct the mobile device user to a dynamically created web page. This methodology can be used to improve immediate and future communications by tailoring the message content and communication platform according to the message recipient's mobile device. The dynamic web page may also be configured to prompt the message recipient to execute a desired action, including downloading a compatible mobile app and changing message delivery preferences in order to optimize communications with the message recipient.Type: ApplicationFiled: January 10, 2014Publication date: June 12, 2014Applicant: Parlant Technology, Inc.Inventors: John Graff, Bruce Hassler, Jacob Hutchings

Patent number: 8658458Abstract: An improved method of manufacturing a polysilicon solar cell is disclosed. To create the polysilicon layer, which has p-type and n-type regions, the layer is grown in the presence of one type of dopant. After the doped polysilicon layer has been created, ions of the opposite dopant conductivity are selectively implanted into portions of the polysilicon layer. This selective implant may be performed using a shadow mask.Type: GrantFiled: June 15, 2011Date of Patent: February 25, 2014Assignee: Varian Semiconductor Equipment Associates, Inc.Inventor: John Graff

Publication number: 20130087189Abstract: An improved method of fabricating an interdigitated back contact (IBC) solar cell is disclosed. A first mask is used to perform a patterned ion implantation of n-type dopant to create the back surface field. A second mask is then used to create the p-type emitter on the same surface. The second mask may be aligned to the n-type implant, and may be used in a plurality of orientations to create the desired p-type emitter. In some embodiments, a p-type blanket implant is performed as well.

Publication number: 20120322192Abstract: An improved solar cell is disclosed. To create the internal p-n junction, one surface of the substrate is implanted with ions. After the implantation, the substrate is thermally treated. The thermal process distributes the dopant throughout the substrate, while repairing crystal damage caused by implantation. After the thermal process, residual crystal damage may remain, which adversely impacts solar cell efficiency. In order to further reduce the residual damage, the uppermost portion of the surface is then removed, thereby eliminating that portion of the substrate where most of the defects reside. The lower defect concentration reduces recombination and improves efficiency of the solar cell.Type: ApplicationFiled: June 15, 2011Publication date: December 20, 2012Applicant: VARIAN SEMICONDUCTOR EQUIPMENT ASSOCIATES, INC.Inventors: John Graff, Nicholas Bateman
