NOVELTY - The method comprises advancing a first segment of a workpiece through a first deposition zone while also dispensing a first electroless deposition solution onto a first segment so that the first deposition solution is flowed over a front surface of an absorber layer (104) of the workpiece towards a second deposition zone, electrolessly depositing a first section of a buffer layer (102) from the first electroless deposition solution on the first segment of the workpiece in the first deposition zone, and advancing the first segment of the workpiece into and through the second deposition zone.    USE - The method is useful for forming a buffer layer over a front surface of a flexible workpiece including an absorber layer during the manufacture of a solar cell.    ADVANTAGE - The method is capable of easily and efficiently forming the buffer layer over the front surface of the flexible workpiece thus economically manufacturing the solar cell with high productivity and reliability, improved light conversion efficiency and enhanced electrical resistivity and without any degradation.    DETAILED DESCRIPTION - The method comprises advancing a first segment of a workpiece through a first deposition zone while also dispensing a first electroless deposition solution onto a first segment so that the first deposition solution is flowed over a front surface of an absorber layer (104) of the workpiece towards a second deposition zone, electrolessly depositing a first section of a buffer layer (102) from the first electroless deposition solution on the first segment of the workpiece in the first deposition zone, advancing the first segment of the workpiece into and through the second deposition zone while also dispensing a second electroless deposition solution over the first section of the buffer layer within the second deposition zone so that the second electroless deposition solution is flowed in a same direction as the advancing first segment within the second deposition zone, and electrolessly depositing a second section of the buffer layer from the second electroless deposition solution on the first section of the buffer layer in the second deposition zone. The flexible workpiece includes a substrate (110), a contact layer (108) disposed over the substrate, and the absorber layer disposed over the contact layer. A second segment of the workpiece adjacent to the first segment of the workpiece is moved into the first deposition zone, and has the first electroless deposition solution as the first segment of the workpiece. Another first section of the buffer layer is deposited from the first electroless deposition solution onto the second segment of the workpiece in the first deposition zone. The first deposition solution is flowed into the second deposition zone. The electroless deposition solution in the second deposition zone is a mixture of the first electroless deposition solution and the second electroless deposition solution. All of the first deposition solution is removed from the surface of the deposited first section of the buffer layer before the second deposition solution is dispensed over the first section of the buffer layer. The first segment of the workpiece is advanced by unrolling and advancing an unprocessed segment of the workpiece from a workpiece supply roll, and taking up a processed segment of the workpiece and then wrapping up as a workpiece receiving roll. The first and second deposition zones are inclined at a predetermined angle of 2-20 degrees to assist in flowing the first and second electroless deposition solutions in the same direction as the advancing direction of the workpiece. An INDEPENDENT CLAIM is included for a method of forming a solar cell.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a solar cell structure including a buffer layer.
