摘要： A method is provided for preparing at least one textured layer in an optoelectronic device. The method includes epitaxially growing a semiconductor layer of the optoelectronic device over a growth substrate; exposing the semiconductor layer to an etching process to create the at least one textured surface on the semiconductor layer; and lifting the optoelectronic device from the growth substrate.

摘要： The disclosure describes various aspects of a metal organic chemical vapor deposition (MOCVD) effluent abatement process. In an aspect, a system for removing toxic waste from an exhaust stream includes a first cold trap that operates at a first pressure and condenses toxic materials in the exhaust stream for removal as solid waste; a pump connected to the first cold trap that increases a pressure of the exhaust stream; a hot cracker connected to the pump that decomposes toxic materials remaining in the exhaust stream after the first cold trap; a second cold trap connected to the hot cracker that operates at a second pressure higher than the first pressure and condenses the decomposed toxic materials remaining in the exhaust stream for removal as solid waste; and a scrubber connected to the second cold trap that absorbs toxic materials remaining in the exhaust stream after the second cold trap.

摘要： Aspects of the present disclosure include methods, apparatuses, and computer readable media for transmitting a light such that is incident on a semiconductor device, detecting a first reflected light from a first layer of the semiconductor device and a second reflected light from a second layer of the semiconductor device, identifying a defect in the first layer based on the first reflected light and the second reflected light, wherein the defect provides a shunt path between a top electrode to be deposited on the first layer and the second layer, and performing a defect reduction procedure on the semiconductor device to compensate for the defect in response to identifying the defect.

摘要： System and method of providing a photovoltaic (PV) cell having a cushion layer to alleviate stress impact between a front metal contact and a thin film PV layer. A cushion layer is disposed between an extraction electrode and a photovoltaic (PV) surface. The cushion layer is made of a nonconductive material and has a plurality of vias filled with a conductive material to provide electrical continuity between the bus bar and the PV layer. The cushion layer may be made of a flexible material preferably with rigidity that matches the substrate. Thus, the cushion layer can effectively protect the PV layer from physical damage due to tactile contact with the front metal contact.
