The present invention refers to a method for producing CdTe thin-film solar cells, respectively a semi-finished CdTe thin-film solar cell, where in an additional temperature step is carried out after applying the CdTe layer on to a substrate. In particular, the temperature step is performed after activating the CdTe layer using a suitable activation agent and removing the residual activation agent from the CdTe layer. The temperature treatment is performed under vacuum or in a heating chamber filled with either air or inert gas, during which treatment the substrate is exposed to a temperature between 180 C. and 380 C. for a time between 5 minutes and 60 minutes. Due to the inventive additional temperature step, the number and extension of crystal defects in the CdTe layer is reduced and the electric efficiency of the solar cell is further improved.

In the 21st century, the engineering survey and design enterprise, which is under intense competition in the domestic market, for conforming to the trend of internationalization, is actively implementing the strategy of internationalization. However, concerning the present situation of the implementation, the internationalization of the engineering survey and design enterprise is still at the exploratory stage, a lot of enterprises have not yet established a relatively complete system of international strategy. Based on this, on the basis of the theories of internationalization and strategic analysis of the engineering survey and design enterprise, this paper constructs the BPSM strategic model which is composed of "main business (B) integration, business process (P) recycling, services (S) network restructuring, the core management (M) system architecture" as core content, and uses "carrier" strategy and "base" strategy to prove the applicability and validity of the BPSM strategic model.

The subject matter of the present invention is a method for treating the CdTe layer of semifinished thin-film solar products in a superstrate configuration, having a CdTe layer as the uppermost layer. According to the state of the art, these surfaces are subjected to an NP etching and are then coated. However, the tellurium oxides formed during the NP etching have proven to be a disadvantage for the subsequent coating steps. It is therefore proposed that the tellurium oxides that are present should be reduced to tellurium using a reducing agent in a further treatment step.

The present invention concerns a method for the manufacture of the first layer of a back contact layer for thin-layer solar cells in superstrate configuration. In the prior art, this layer is deposited as a compound, for example as a layer of Sb_(2)Te_(3). In accordance with the invention, however, a tellurium-rich surface layer of the cadmium telluride layer is produced, on which a first material is deposited which is capable of forming an electrically conductive second material with tellurium and of producing the second material by reaction of the first material and tellurium in the surface layer. The second material forms the first layer of the back contact layer.

The present invention concerns a method for the manufacture of a partially transparent thin-layer solar module in which the opaque layers (primarily the semiconductor layer and the back contact layer) comprise defined surface regions which lack the material of these layers. These surface regions which are free of material may be produced by not coating them during manufacture or by retroactively removing them from the surface regions.

The present invention proposes a method to produce thin film CdTe solar cells having a pin-hole free and uniformly doped CdTe layer with a reduced layer thickness. The method according to the present invention is an efficient way to prevent shunting of the solar cells, to improve reliability and long-term stability of the solar cells and to provide a uniform doping of the CdTe layer. This is achieved by applying a sacrificial doping layer between a first CdTe layer having large grains and a second CdTe layer having small grains, which together form the CdTe layer of the solar cells. Furthermore it provides the possibility to eliminate the CdCl_(2 )activation treatment step in case the sacrificial doping layer comprises a halogen.

A method to produce thin film solar cells in superstrate or substrate configuration is an efficient way to minimize the loss due to absorption in CdS layer and to eliminate the CdCl_(2 )activation treatment step. This is achieved by applying a sacrificial metal-halide layer between the CdS-layer and the CdTe-layer of the solar cells.

The present invention concerns an improved method for the manufacture of CdTe thin-layer solar cells or a semi-finished product therefor, which provides for the application of an additional, adhesion-promoting layer which is applied to the front contact layer following its deposition in order to improve the growth of the subsequent CdS layer; it also concerns a thin-layer solar cell produced by said method. CdTe is a particularly preferred material for the adhesion-promoting layer, which is preferably a monolayer.
