NOVELTY - Thin film solar cell module (1, 71, 91) comprises (a) a layer (5, 72, 93) of transparent conductive oxide (TCO) applied on a glass substrate (4, 73, 92), (b) a semiconductor layer (10, 76, 97) disposed on the layer (5, 72, 93) comprised of TCO, and (c) an electrically conducting backside layer (63, 85, 104) applied on the semiconductor layer (10, 76, 97), where the backside layer (63, 85, 104) is connected with the layer (5, 72, 93) of TCO via bridge elements (22-24, 88; 89, 106; 107).    USE - The thin film solar cell module is used to convert the energy of sunlight directly into electricity.    ADVANTAGE - The present invention provides a thin film solar cell module in which the conventional metal filaments are replaced by busbars whose thickness is very low and which are securely disposed on the thin film solar cell module. The busbars can be applied very simply on the thin film solar cell module. The application of these busbars takes place by printing methods, for example using an inkjet printing method. These printing methods can be readily automated and are thus cost-effective. The thus produced busbars have a very low thickness and are directly in contact on the metal layer of the thin film solar cell modules. However, it is also feasible to dispose the busbars within the thin film solar cell module. If the thin film solar cell modules are provided with a protective layer, no bubble formation occurs any longer. These thin- film solar cell modules according to the invention, further, have a high long-term stability.    DETAILED DESCRIPTION - Thin film solar cell module (1, 71, 91) comprises (a) a layer (5, 72, 93) of TCO applied on a glass substrate (4, 73, 92), (b) a semiconductor layer (10, 76, 97) disposed on the layer (5, 72, 93) comprised of TCO, and (c) an electrically conducting backside layer (63, 85, 104) applied on the semiconductor layer (10, 76, 97), where the backside layer (63, 85, 104) is connected with the layer (5, 72, 93) of TCO via bridge elements (22-24, 88; 89, 106; 107), where at least two busbars (2, 3; 82; 103) located opposite one another are provided, which are connected with the backside layer (63, 85, 104) and are applied by using printing methods.
