NOVELTY - A solar energy hull cell laser lithography device comprises stander, Y axis foundation support, workholder and etching system. The stander is fixedly connected with Y axis foundation support, where 2 sets of etching system are installed on the foundation support of Y axis in opposite direction. The etching system comprises X axis moving system, X axis foundation support, Y axis moving system and optical maser system. The workholder with its circumjacent gripping holder installed on stander is located on upper part of middle part of the Y axis foundation support.    USE - Solar energy hull cell laser lithography device.    ADVANTAGE - The device increases manufacturing efficiency and quality of product. The feeding distance of Y axis is short. The method is simple.    DETAILED DESCRIPTION - The solar energy hull cell laser lithography device comprises stander, Y axis foundation support, workholder and etching system. The stander is fixedly connected with Y axis foundation support, where 2 sets of etching system are installed on the foundation support of Y axis in opposite direction. The etching system comprises X axis moving system, X axis foundation support, Y axis moving system and optical maser system. The workholder with its circumjacent gripping holder installed on stander is located on upper part of middle part of the Y axis foundation support. The center supporting device of workholder is installed on mainstay located on middle part of foundation support. The optical maser system with its etching head stretched to the lower part of the workholder is installed on the X axis moving system. An INDEPENDENT CLAIM is included for a solar energy hull cell laser lithography comprising providing 2 sets of etching systems with its etching head of optical maser distributed in opposite directions; and performing etching movement along U route, and then completing etching for periphery of the workpiece together.    DESCRIPTION OF DRAWING(S) - The drawing is a cross-sectional view illustrating a solar energy hull cell laser lithography device.
