20110114157 | METHOD FOR THE PRODCUTION OF A MONOGRAIN MEMBRANE FOR A SOLAR CELL, MONOGRAIN MEMBRANE, AND SOLAR CELL - The invention relates to a method for producing a monograin membrane and a monograin membrane produced according to said method. The invention further relates to the production of a solar cell from such a monograin membrane as well as a produced solar cell. The monograin membranes produced according to the invention can also be used for other applications, e.g. for converting electric energy into radiation energy or in detectors for detecting radiation. The aim of the invention is to improve the production of monograin membranes and solar cells. Said aim is achieved by first preparing a horizontally oriented layer made of a binder that is not yet cured or cross-linked such that the binder is liquid or at least viscous. Grains are partially introduced into the layer through a surface of the layer in such a way that only a portion of each grain is immersed in the layer and a zone of the grain remains above the surface of the layer. As a result, the zone of the grain that remains above the surface of a binder is definitely not moistened by a binder. The binder is then solidified, e.g. in a curing or cross-linking process. The obtained monograin membrane comprises grains which protrude on one side and the surface of which is definitely not provided with binder or binder residues or any other glues, adhesives, or glue residues. | 05-19-2011 |
