Disclosed herein are methods for using cracked film lithography (CFL) for patterning transparent conductive metal grids. CFL can be vacuum- and Ag-free, and it forms more durable grids than nanowire approaches.

High-performance metal grids for solar cells formed by cracked film lithography

Disclosed herein are CdTe-based solar cells that are successfully removed from their glass superstrate through a combination of lamination to a backsheet followed by thermal shock.

Controlled thermomechanical delamination of thin films

Systems and methods for growing high-quality CdTe-based materials at high growth rates are provided. According to an aspect of the invention, a method includes depositing a first CdTe-based layer on a CdTe-based template at a rate of greater than 1 &#x3bc;m/min. Each of the first CdTe-based layer and the CdTe-based template has a single-crystal structure and/or a large-grain polycrystalline structure. The depositing is performed by physical vapor deposition.

Methods of growing CdTe-based materials at high rates

A permeation standard is provided. The permeation standard may include a substrate that is impermeable to an analyte, an orifice disposed in the substrate, and a permeable material filling the orifice. The orifice and the permeable material are configured to provide a predetermined transmission rate of the analyte through the permeation standard. Also provided herein are methods for forming the permeation standard.

Calibrated permeation standards

In one embodiment, a method for surface passivation for CdTe devices is provided. The method includes adjusting a stoichiometry of a surface of a CdTe material layer such that the surface becomes at least one of stoichiometric or Cd-rich; and reconstructing a crystalline lattice at the surface of the CdTe material layer by annealing the adjusted surface.

Surface passivation for CdTe devices

A method of synthesizing multilayer heterostructures including an inorganic oxide layer residing on a solid substrate is described. Exemplary embodiments include producing an inorganic oxide layer on a solid substrate by a liquid coating process under relatively mild conditions. The relatively mild conditions include temperatures below 225&#xb0; C. and pressures above 9.4 mb. In an exemplary embodiment, a solution of diethyl aluminum ethoxide in anhydrous diglyme is applied to a flexible solid substrate by slot-die coating at ambient atmospheric pressure, and the diglyme removed by evaporation. An AlOlayer is formed by subjecting material remaining on the solid substrate to a relatively mild oven temperature of approximately 150&#xb0; C. The resulting AlOlayer exhibits relatively high light transmittance and relatively low vapor transmission rates for water. An exemplary embodiment of a flexible solid substrate is polyethylene napthalate (PEN). The PEN is not substantially adversely affected by exposure to 150&#xb0; C.

Multilayer heterostructures and their manufacture

A method of producing polycrystalline CdTe materials and devices that incorporate the polycrystalline CdTe materials are provided. In particular, a method of producing polycrystalline p-doped CdTe thin films for use in CdTe solar cells in which the CdTe thin films possess enhanced acceptor densities and minority carrier lifetimes, resulting in enhanced efficiency of the solar cells containing the CdTe material are provided.

CdTe devices and method of manufacturing same

A test device for measuring permeability of a barrier material. An exemplary device comprises a test card having a thin-film conductor-pattern formed thereon and an edge seal which seals the test card to the barrier material. Another exemplary embodiment is an electrical calcium test device comprising: a test card an impermeable spacer, an edge seal which seals the test card to the spacer and an edge seal which seals the spacer to the barrier material.
