20100313932 | METHOD FOR OBTAINING HIGH PERFORMANCE THIN FILM DEVICES DEPOSITED ON HIGHLY TEXTURED SUBSTRATES - The present invention provides an improved thin film solar cell, wherein at least one additional resistive transparent conductive oxide (TCO) layer is incorporated into the solar cell. The additional resistive TCO electrically separates the conductive TCO layers acting as electrodes of such a cell and thus decreases or prevents performance losses. Furthermore, methods for the production of such solar cells are disclosed. | 12-16-2010 |
