1. A method of manufacture of an article combining photovoltaic cell structure and a current collector structure suitable for collecting current from a light incident surface of a photovoltaic cell, said method comprising the steps of,providing photovoltaic cell structure having a top light incident surface and comprising semiconductor material,providing a flexible current collector structure, said current collector structure comprising a polymer based sheetlike substrate having a first substrate surface formed by a first material having adhesive affinity for said top light incident surface and said current collector structure further having a pattern comprising electrically conductive second material supported by said substrate and positioned on said first substrate surface, said current collector structure being manufactured separately and distinctly from said cell structure,combining a first portion of said current collector structure and said cell structure such that said first substrate surface of said first collector structure portion and said top light incident surface of said cell structure face each other so that said conductive material associated with said first collector structure portion contacts said top light incident surface and said pattern is distributed over a preponderance of said top light incident surface, wherein said photovoltaic cell structure is provided to said combining step as a continuous form.
