摘要:
A solar cell includes a substrate, a protective layer located over a first surface of the substrate, a first electrode located over a second surface of the substrate, at least one p-type semiconductor absorber layer located over the first electrode, an n-type semiconductor layer located over the p-type semiconductor absorber layer, and a second electrode over the n-type semiconductor layer. The p-type semiconductor absorber layer includes a copper indium selenide (CIS) based alloy material, and the second electrode is transparent and electrically conductive. The protective layer has an emissivity greater than 0.25 at a wavelength of 2 μm, has a reactivity with a selenium-containing gas lower than that of the substrate, and may differ from the first electrode in at least one of composition, thickness, density, emissivity, conductivity or stress state. The emissivity profile of the protective layer may be uniform or non-uniform.

The light detection system includes at least two light detection elements. Each element is responsive to a selected light color in a first mode, and each element has a different sensitivity and is responsive to a single color in a second mode for enhanced dynamic range. A preferred embodiment includes four light detectors for responding to four separate colors or for responding with enhanced dynamic range to two colors. Embodiments are disclosed using a mirror/beam splitter arrangement to switch between modes and an embodiment including dichroic filters serving as fractional beam splitters.
摘要:
An automated method and system for determining an optimal focus distance for scanning a molecular array by a molecular array scanner. Blocks of rows of a reference array are automatically scanned at successively greater distances of the stage from a light gathering medium, such as an optical fiber, or z-positions, to produce data providing a functional relationship between z-position and measured signal intensities. The data is then processed by a peak-height-based, or window-based, focus-finding routine that selects an optimal focus-distance for data scans.

A method and system for estimating a global background-signal correction for each channel of a microarray data set. The method and system of one embodiment of the present invention is directed to a method for calculating background corrected signals for a microarray data set by receiving a non-negative constant and selects a set of low-combined-intensity features from the microarray data set. Based on the low-combined-intensity features, a representation that describes a central-trend of the selected set of low-combined-intensity features is determined in signal-intensity space. The method adjusts the microarray data set parallel to the determined representation based on the non-negative constant.

Methods, systems and computer readable media for automatically feature extracting array images in batch mode. At least two images to be feature extracted are loaded into a batch project, and the system automatically and sequentially feature extracts the images in the batch project. At least one of the images may be feature extracted based upon a different grid template or protocol than at least one other of the images. Methods, systems and computer readable media are provided to automatically feature extract a single array image having an identifier indicating that it is a multipack, multiple array image. A system provided for feature extracting array images in batch mode includes a user interface with a feature enabling a user to select images to be loaded into a batch project; and based upon the loaded images in the batch project, the system may automatically assign a grid template to each image loaded into the batch project. Further, the system may automatically assign a protocol to each image loaded into the batch project.

Methods for identifying feature boundary pixels are provided. In general, the subject methods involve evaluating a pixel signal to identify any difference in amplitude between a first part of the signal and a second part of the signal. If the difference is significant, the pixel signal may be indicated as a pixel representing a feature boundary. Also provided are systems and programming for performing the subject methods, and an array scanner containing these systems and programming.
