Abstract
A method for producing a thin-film solar cell with a cell level integrated bypass diode includes forming at least three series-connected solar cells, each cell being a laminated structure including semiconducting material of first and second types, a front electrode in contact with the material of the first type, and a back electrode in contact with the material of the second type. The bypass diode is formed by total separation from a selected parent cell. The material of the first type of the diode is connected to the material of the second type of any one chosen solar cell in the array. The material of the second type of the diode is connected with the material of the first type of the one chosen solar cell in the array so that the diode is connected in parallel and in opposition to the one chosen solar cell.
