  • Silicon: hydrogen photovoltaic devices, such as solar cells, having reduced light induced degradation and method of making such devices
    Patent number: 8927857
    Abstract: A method of producing a photovoltaic device includes providing a stretchable substrate for the photovoltaic device; and stretching the substrate to produce a stretched substrate. The method further includes depositing a structure comprising hydrogenated amorphous silicon onto the stretched substrate; and subjecting the deposited hydrogenated amorphous silicon structure and the stretched substrate to a compressive force to form a compressively strained photovoltaic device.
    Type: Grant
    Filed: February 28, 2011
    Date of Patent: January 6, 2015
    Assignee: International Business Machines Corporation
    Inventors: Ahmed Abou-Kandil, Nasser Afify, Wanda Andreoni, Alessandro Curioni, Augustin J. Hong, Jeehwan Kim, Petr Khomyakov, Devendra K. Sadana
