(Targeted News Service Via Acquire Media NewsEdge) By Targeted News Service
ALEXANDRIA, Va., March 23 -- Solexel, Milpitas, Calif., has been assigned a patent (8,399,331) developed by four co-inventors for a "laser processing for high-efficiency thin crystalline silicon solar cell fabrication." The co-inventors are Mehrdad M. Moslehi, Los Altos, Calif., Virendra V. Rana, Los Gatos, Calif., JianJun Liang, Fremont, Calif., and Pranav Anbalagan, San Jose, Calif.
The abstract of the patent published by the U.S. Patent and Trademark Office states: "Laser processing schemes are disclosed for producing various types of hetero-junction and homo-junction solar cells. The methods include base and emitter contact opening, selective doping, and metal ablation. Also, laser processing schemes are disclosed that are suitable for selective amorphous silicon ablation and selective doping for hetero-junction solar cells. These laser processing techniques may be applied to semiconductor substrates, including crystalline silicon substrates, and further including crystalline silicon substrates which are manufactured either through wire saw wafering methods or via epitaxial deposition processes, that are either planar or textured/three-dimensional. These techniques are highly suited to thin crystalline semiconductor, including thin crystalline silicon films."
The patent application was filed on May 27, 2011 (13/118,295). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,399,331&OS=8,399,331&RS=8,399,331
