摘要:
Methods of promoting adhesion between a reflective backing layer and a solar cell substrate are provided. The reflective backing layer is formed over a conductive metal oxide layer as an alloy using reflective and adhesive components, the adhesive components being present in levels generally below about 5 atomic percent. Techniques are disclosed for depositing varying the concentration of the reflective backing layer to localize the adhesive components in an adhesion region near the conductive metal oxide layer. Techniques are also disclosed for boosting bonding species in the conductive metal oxide layer to further enhance adhesion.

The present invention generally relates to a system that can be used to form a photovoltaic device, or solar cell, using processing modules that are adapted to perform one or more steps in the solar cell formation process. The automated solar cell fab is generally an arrangement of automated processing modules and automation equipment that is used to form solar cell devices. The automated solar fab will thus generally comprise a substrate receiving module that is adapted to receive a substrate, one or more absorbing layer deposition cluster tools having at least one processing chamber that is adapted to deposit a silicon-containing layer on a surface of the substrate, one or more back contact deposition chambers, one or more material removal chambers, a solar cell encapsulation device, an autoclave module, an automated junction box attaching module, and one or more quality assurance modules that are adapted to test and qualify the completely formed solar cell device.

A method and system for interactively configuring a network device is disclosed. A computer based method interactively configures a network device such as a router. A document is displayed a to a user of a client computer, which is coupled to the network device via a network. The document contains a configuration for the network device in a text format. The user edits the document to make a change in the configuration of the network device. The change in the configuration is sent to the network device. The change can be sent without sending the entire configuration.

The instant disclosure provides a child safety seat alarm to notify the driver of a vehicle that an infant is in its carrier inside of the vehicle when a personal electronic device carried by the driver is moved a great distance from the carrier. The instant disclosure provides a computer application for notification of user selected contacts via SMS messaging, e-mail messaging, or social media alerts.
摘要:
A novel method is described to create low-relief texture at a light-facing surface or a back surface of a photovoltaic cell. The peak-to-valley height and average peak-to-peak distance of the textured surface is less than about 1 microns, for example less than about 0.8 micron, for example about 0.5 microns or less. In a completed photovoltaic device, average reflectance for light having wavelength between 375 and 1010 nm at a light-facing surface with this texture is 6 percent or less, for example about 5 percent or less, in some instances about 3.5 percent. This texture is produced by forming an optional oxide layer at the surface, lightly buffing the surface, and etching with a crystallographically selective etch. Excellent texture may be produced by etching for as little as twelve minutes or less. Very little silicon, for example about 0.3 mg/cm2 or less, is lost at the textured surface during this etch.
