摘要:
A tracking photovoltaic solar system, and methods for installing or for using such tracking comprising at least a dual axis tracker unit maintaining an array of photovoltaic modules aligned to the sun. Said tracker unit includes: a pair of sub-frames supporting photovoltaic modules, a torque tube supporting said subframes rotating around a primary rotation axis, a pole structure fixed and extending vertically above an anchoring basis and being rotatively connected to said longitudinal support, secondary rotating means controlling the orientation of said sub-frames around corresponding secondary rotation axis of said sub-frames, said secondary rotation axis being orthogonal to said primary rotation axis and actuators means for controlling said primary and secondary rotating means. The secondary rotation axis are located at each end of said torque tube, said pole structure being central with regard to said sub-frames and said actuators means of both primary and secondary rotating means are linear.

In a method of printing a transferable component, a stamp including an elastomeric post having three-dimensional relief features protruding from a surface thereof is pressed against a component on a donor substrate with a first pressure that is sufficient to mechanically deform the relief features and a region of the post between the relief features to contact the component over a first contact area. The stamp is retracted from the donor substrate such that the component is adhered to the stamp. The stamp including the component adhered thereto is pressed against a receiving substrate with a second pressure that is less than the first pressure to contact the component over a second contact area that is smaller than the first contact area. The stamp is then retracted from the receiving substrate to delaminate the component from the stamp and print the component onto the receiving substrate. Related apparatus and stamps are also discussed.
摘要:
A large-format substrate with distributed control elements is formed by providing a substrate and a wafer, the wafer having a plurality of separate, independent chiplets formed thereon; imaging the wafer and analyzing the wafer image to determine which of the chiplets are defective; removing the defective chiplet(s) from the wafer leaving remaining chiplets in place on the wafer; printing the remaining chiplet(s) onto the substrate forming empty chiplet location(s); and printing additional chiplet(s) from the same or a different wafer into the empty chiplet location(s).

摘要:
The present invention provides methods, systems and system components for transferring, assembling and integrating features and arrays of features having selected nanosized and/or microsized physical dimensions, shapes and spatial orientations. Methods of the present invention utilize principles of ‘soft adhesion’ to guide the transfer, assembly and/or integration of features, such as printable semiconductor elements or other components of electronic devices. Methods of the present invention are useful for transferring features from a donor substrate to the transfer surface of an elastomeric transfer device and, optionally, from the transfer surface of an elastomeric transfer device to the receiving surface of a receiving substrate. The present methods and systems provide highly efficient, registered transfer of features and arrays of features, such as printable semiconductor element, in a concerted manner that maintains the relative spatial orientations of transferred features.

Provided are methods for making a device or device component by providing a multilayer structure having a plurality of functional layers and a plurality of release layers and releasing the functional layers from the multilayer structure by separating one or more of the release layers to generate a plurality of transferable structures. The transferable structures are printed onto a device substrate or device component supported by a device substrate. The methods and systems provide means for making high-quality and low-cost photovoltaic devices, transferable semiconductor structures, (opto-)electronic devices and device components.

Provided are reinforced composite stamps, devices and methods of making the reinforced composite stamps disclosed herein. Reinforced composite stamps of certain aspects of the present invention have a composition and architecture optimized for use in printing systems for dry transfer printing of semiconductor structures, and impart excellent control over relative spatial placement accuracy of the semiconductor structures being transferred. In some embodiments, for example, reinforced composite stamps of the present invention allow for precise and repeatable vertical motion of the patterned surface of the printing apparatus with self-leveling of the stamp to the surface of a contacted substrate. Reinforced composite stamps of certain aspect of the present invention achieve a uniform distribution of contact forces between the printing apparatus patterned surface and the top surface of a substrate being contacted by the reinforced composite stamp of the printing apparatus.
