Manufacturing Semiconductor-Based Multi-Junction Photovoltaic Devices

View page
US Patent:
20130344645, Dec 26, 2013
Filed:
Jun 21, 2013
Appl. No.:
13/924242
Inventors:
Swee LIM - Champaign IL, US
Shiva RAI - Champaign IL, US
David FORBES - Medina OH, US
International Classification:
H01L 31/0336
US Classification:
438 94
Abstract:
Manufacture of multi-junction solar cells, and devices thereof, are disclosed. The architectures are also adapted to provide for a more uniform and consistent fabrication of the solar cell structures, leading to improved yields and lower costs. Certain solar cells may further include one or more compositional gradients of one or more semiconductor elements in one or more semiconductor layers, resulting in a more optimal solar cell device.

Formation Of Iii-V Materials Using Mocvd With Chlorine Cleans Operations

View page
US Patent:
20130005118, Jan 3, 2013
Filed:
Jun 28, 2012
Appl. No.:
13/535845
Inventors:
Sung Won Jun - Cupertino CA, US
Yan Wang - Sunnyvale CA, US
Hua Chung - San Jose CA, US
Jiang Lu - Milpitas CA, US
Kuan Chien Keris Shen - Santa Clara CA, US
Shiva Rai - Champaign IL, US
International Classification:
H01L 21/205
US Classification:
438478, 257E21112
Abstract:
Methods of forming III-V materials using metal organic chemical vapor deposition (MOCVD) with chlorine cleans operations are described. A chlorine-clean operation may further season an MOCVD process for improved throughput for high volume manufacturing.

Methods And Apparatus For Forming Light Emitting Diodes

US Patent:
20220216363, Jul 7, 2022
Filed:
Jan 6, 2021
Appl. No.:
17/142752
Inventors:
- Santa Clara CA, US
Shiva RAI - Fremont CA, US
International Classification:
H01L 33/00
Abstract:
A method for forming a light emitting diode (LED) uses aluminum-based material layers and oxidation during the LED formation. In some embodiments, the method may include forming an n-type layer of the LED on a substrate, forming at least one sidewall restriction layer of the LED on the substrate with the sidewall restriction layer comprising an aluminum-based material, forming a quantum well layer of the LED on the substrate, forming a p-type layer of the LED on the substrate, exposing the substrate to water vapor, and heating the substrate to oxidize at least an outer portion of the electron blocking layer. The aluminum-based material may include aluminum indium nitride or aluminum gallium arsenide.

Drivers With Simplified Connectivity For Controls

US Patent:
20210251059, Aug 12, 2021
Filed:
Apr 12, 2021
Appl. No.:
17/228013
Inventors:
- Fremont CA, US
Shiva Rai - Fremont CA, US
Sudeep Reddy Dodda - San Jose CA, US
International Classification:
H05B 45/20
H05B 47/19
F21V 23/00
F21V 23/06
Abstract:
A lighting module may receive control signal having a first control scheme, the lighting module including a driver including at least one channel; and a control module; where the control module translates the received first control scheme into a predetermined second control scheme, when the first control scheme is different from the predetermined second control scheme; wherein the control module generates an identity voltage correlated with the received first control scheme; wherein the control module outputs to the driver a driver control signal including the predetermined second control scheme, and the identity voltage; and wherein the driver generates a driver output based on the identity voltage and the driver control signal.

US Patent:
20200288546, Sep 10, 2020
Filed:
Mar 5, 2019
Appl. No.:
16/292607
Inventors:
- Fremont CA, US
Shiva Rai - Fremont CA, US
Sudeep Reddy Dodda - San Jose CA, US
International Classification:
H05B 33/08
F21V 23/00
F21V 23/06
H05B 37/02
Abstract:
There is provided a system comprising a driver and a control module, the control module capable of translating a received control signal having a first control scheme into a driver control signal having a predetermined second control scheme; and wherein the driver is configured for generating a driver output based on the identity of the first control scheme and the driver control signal. A driver, control module, and a method of controlling an LED system are also provided.

US Patent:
20170345962, Nov 30, 2017
Filed:
Aug 18, 2017
Appl. No.:
15/680426
Inventors:
- Champaign IL, US
Swee Lim - Champaign IL, US
Shiva Rai - Champaign IL, US
David Forbes - Medina OH, US
International Classification:
H01L 31/18
H01L 31/0336
H01L 31/065
H01L 31/0735
H01L 31/072
H01L 31/0725
H01L 31/076
Abstract:
Manufacture of multi-junction solar cells, and devices thereof, are disclosed. The architectures are also adapted to provide for a more uniform and consistent fabrication of the solar cell structures, leading to improved yields, greater efficiency, and lower costs. Certain solar cells may be from a different manufacturing process and further include one or more compositional gradients of one or more semiconductor elements in one or more semiconductor layers, resulting in a more optimal solar cell device.
