摘要： The invention relates to a method for producing solar cells comprising at least one p-i-n layer sequence containing micro-crystalline layers with the aid of a PECVD method. Said method is characterised in that all layers of the p-i-n layer sequence are deposited in a single-chamber process. The electrodes are interspaced at a distance of between 5 and 15 mm and the gas is distributed by means of a shower-head gas inlet, which guarantees a homogeneous distribution of the gas over the substrate. SiH4 gas streams with values of between 0.01 and 3 sccm/cm2 are added with a process pressure of between 8 and 50 hPa. The heater temperature is set at between 50 and 280° C. and the HF output is between 0.2 and 2 watt/cm2. The H2 gas streams have values of between 0.3 and 30 sccm/cm2, in particular between 0.3 and 10 sccm/cm2.

摘要： The invention relates to a method for the production of a conductive and transparent zinc oxide layer on a substrate by reactive sputtering. The process comprises a hysteresis region. Said method is characterised by the following steps: A doped metal Zn target is used, whereby the doping content of the target is less than 2.3 at-%, the heater is adjusted for the substrate in such a manner that a substrate temperature is adjusted to above 200° C. A dynamic deposition rate is adjusted to more than 50 nm*m/min, which corresponds to a static deposition rate which is greater than 190 nm/min, and a stabilised working point is selected within the unstable process range which is between the turning point between a stable, metal and unstable process and between the inflection point of the stabilised process curve.

摘要： A thin-film solar module contacted on one side includes a support layer, a photoactive absorber layer and at least one dopant layer deposited over a surface area of at least one side of the absorber layer so as to form a thin-film packet that is divided into thin-film solar cell areas by insulating separating trenches. The thin-film solar module includes first and second contact systems. The first contact system includes contacts connected by an outer contact layer. The second contact system consists of an inner contact layer covering a side of the solar cell areas that face away from the support layer so as to separately discharge excess charge carriers generated by incident light in the absorber layer. The second contact system includes structures that surround and electrically insulate the contacts, which extend through the inner contact layer from the outer contact layer. The first and second contact systems are electrically conductive and connected in series by series contacts in interconnection areas and electrically insulated from each other by an insulation layer outside of the interconnection areas.

摘要： A simple process is disclosed for treating substrates having pre-structured zinc oxide layers on rigid or flexible supports. The ZnO is treated with an etching medium then with a cleaning liquid. The treatment with the etching and cleaning liquids is carried out while the substrate is conveyed through a device. The process is technically simple to implement and makes it possible to regularly and homogeneously roughen and texturize ZnO layers of up to 1 m2. The device for treating substrates having pre-structured zinc oxide layers on rigid or flexible supports has for that purpose a first means for treating the substrate with an etching liquid, a second means for treating the substrate with a cleaning liquid, and another means, in particular transport rollers, for conveying the substrate from the first to the second means.

摘要： The inventive method for depositing silicon onto a substrate firstly involves the introduction of a reactive silicon-containing gas and hydrogen into the plasma chamber and then the initiation of the plasma. After initiating the plasma, only reactive silicon-containing gas or a gas mixture containing hydrogen is supplied to the plasma chamber in an alternatively continuous manner, and the gas mixture located inside the chamber is, at least in part, simultaneously withdrawn from the chamber. From the start, homogeneous microcrystalline silicon is deposited onto the substrate in the presence of hydrogen.
