Abstract: Contacts for solar cells and other optoelectronic devices are provided. Embodiments described herein take advantage of the surface Fermi level pinning effect to build an electrical field inside of a semiconductor to extract or inject carriers for solar cells, photodetectors, and light-emitting device applications. For example, n-type or p-type two-dimensional (2D) materials can be used in contact with an n-type semiconductor to form a “p-region” so that a p-n junction, or an i-n or n-n+ junction can be constructed. Similarly, n-type or p-type 2D materials can be used in contact with a p-type semiconductor to form an “n-region” so that an n-p junction, or an i-p or p-p+ junction can be constructed. These structures can provide sufficiently high electrical field inside the semiconductor to extract photogenerated carriers in solar cells and photodetectors or inject minority carriers for light-emitting devices.

Abstract: The present invention relates to a skid-mounted cold box and its prefabricated structure and assembly method. Each prefabricated structure includes a framework and a first panel that is used to enclose sides of the framework. Ring beams of two adjacent prefabricated structures are connected through bolts on site. A second panel connected through bolts encloses the gap between ring beams of the two adjacent prefabricated structures from sides. The present invention cancels all field welding seams and omits the field welding and nondestructive testing operations. The crane can be dismissed after the upper prefabricated structure of the cold box is lifted into place and bolts corresponding to columns on ring beams are connected. The present invention guarantees the connection strength of steel structures relying on bolt-based connection between ring beams and the second panel connected through bolts guarantees the airtightness of the cold box. This effectively reduces field assembly work and saves time and cost.
