Methods of fabricating optoelectronic devices using semiconductor-particle monolayers and devices made thereby

摘要

Methods of fabricating optoelectronic devices, such as photovoltaic cells and light-emitting devices. In one embodiment, such a method includes providing a substrate, applying a monolayer of semiconductor particles to the substrate, and encasing the monolayer with one or more coatings so as to form an encased-particle layer. At some point during the method, the substrate is removed so as to expose the reverse side of the encased-particle layer and further processing is performed on the reverse side. When a device made using such a method has been completed and installed into an electrical circuit the semiconductor particles actively participate in the photoelectric effect or generation of light, depending on the type of device.

1. A method of fabricating an optoelectronic device, comprising:
providing a first substrate having a first surface; applying a monolayer of semiconductor particles to the first surface; encasing the semiconductor particles of the monolayer with one or more coatings so as to form an encased-particle layer having an interface side confronting the first surface of the first substrate; separating the first substrate and the encased-particle layer from one another so as to expose the interface side of the encased-particle layer; and processing the interface side of the encased-particle layer to at least include a first electrode.
