Methods And Apparatus For Patterning Photovoltaic Devices And Materials For Use With Such Devices
US Patent:
2013024, Sep 19, 2013
Filed:
Sep 6, 2011
Appl. No.:
13/820997
Inventors:
Brian W. Baird - Portland OR, US
Timothy D. Gerke - Portland OR, US
Timothy D. Gerke - Portland OR, US
Assignee:
FIANIUM LTD. - Southampton
International Classification:
H01L 31/18, H01L 21/78
US Classification:
438795, 2504922
Abstract:
A picosecond laser beam shaping assembly is disclosed for shaping a picosecond laser beam for use in patterning (e.g., scribing) semiconductor devices. The assembly comprises a pulsed fibre laser source of picosecond laser pulses, a harmonic conversion element for converting laser pulses at a first laser wavelength having a first spectral bandwidth to laser pulses at a second laser wavelength having a second spectral bandwidth, and a beam shaping apparatus for shaping the laser beam at the second laser wavelength, the beam shaping apparatus having a spectral bandwidth that substantially corresponds to the second spectral bandwidth so as to produce a laser beam having a substantially rectangular cross-sectional profile.

Assignee:
FIANIUM LTD. - Southampton
International Classification:
H01L 31/0236, H01L 31/18
US Classification:
136256, 438 69, 438 68
Abstract:
A method comprising providing a layer structure for a photovoltaic device, the layer structure comprising an electrode, a light absorber comprising a layer of chalcopyrite-type semiconductor material, such as copper indium gallium diselenide, disposed on the electrode and a transparent electrode disposed on the light absorber. The method also comprises delivering a spatially-shaped picosecond pulsed laser beam so as to remove material from a region of the transparent electrode so as to expose at least a portion of the light absorber.
