  • High efficiency thin film transistor device with gallium arsenide layer
    Patent number: 8846437
    Abstract: Embodiments of the invention provide a method of forming a doped gallium arsenide based (GaAs) layer from a solution based precursor. The doped gallium arsenide based (GaAs) layer formed from the solution based precursor may assist solar cell devices to improve light absorption and conversion efficiency. In one embodiment, a method of forming a solar cell device includes forming a first layer with a first type of dopants doped therein over a surface of a substrate, forming a GaAs based layer on the first layer, and forming a second layer with a second type of dopants doped therein on the GaAs based layer.
    Type: Grant
    Filed: September 30, 2011
    Date of Patent: September 30, 2014
    Assignee: Applied Materials, Inc.
    Inventors: Kaushal K. Singh, Robert Jan Visser, Srikant Rao, Bhaskar Kumar, Claire J. Carmalt, Ranga Rao Arnepalli, Omkaram Nalamasu, Gaurav Saraf, Sanjayan Sathasivam, Christopher Stuart Blackman
