Abstract
A thin film solar cell has a rough surface layer formed by nano/micro particle conductor balls, which is provided by a method of producing a textured surface for a conductive layer of the solar cell by mounting the nano/micro particle conductor balls with a particle diameter of 50 nm to 150 nm onto the conductive layer by spray coating, spin coating, dip coating, natural deposition or gain, and a monolayer or multilayer self-assembled or random textured structure is achieved and applied in a thin film solar cell, so as to effectively reduce the thickness of an intrinsic semiconductor and greatly lower the manufacturing cost of the solar cell.
