摘要： In continuous apparatus for the glow discharge deposition of amorphous silicon alloy solar cells of p-i-n-type configuration in a plurality of interconnected, dedicated deposition chambers, a plasma bar operatively disposed between at least the plasma regions in which the layer pairs of amorphous silicon alloy material defining the major semiconductor junction of the solar cell are deposited. The plasma bar is adapted to initiate a plasma so as to prevent chemically adsorbed contaminants from deleteriously affecting the surface of the first deposited of the layer pair, thereby improving the open circuit voltage of the solar cell. In a similar manner, the plasma bar may also be provided between the layer pairs of amorphous silicon alloy material which combine to define the minor semiconductor junction of the solar cell. Finally, a plasma bar may be disposed between the oxide-based layer of a back reflector for reducing oxygen contamination of the silicon alloy material deposited thereupon.

摘要： An improved gas gate (34) is adapted to operatively interconnect to adjacent chambers in which process gases are introduced for depositing a first layer (16) upon a substrate (11) in a first chamber (28) and different process gases are introduced for depositing a second layer (18) in the second chamber (30) in continuous low pressure glow dicharge deposition process. A plurality of electrodes (60) and grounded shields (62) are positioned in the isolation passageway (92) of gas gate (34). The electrodes (60) have a potential sufficient to create a plasma from any gas molecule escaping from one of the deposition chambers. After the plasma is formed it is attracted to and captured or plated on the shield (62) preventing the gas plasma from landing on the substrate material (11) or passing through the gas gate. The present invention reduces the back diffusion of gases through the gas gate by actively eliminating free gas molecules by ionizing them to form a plasma and capturing the plasma ions in a permanent fashion.

摘要翻译： 改进的气体浇口（34）适于可操作地互连到邻近的室，其中在第一室（28）中引入工艺气体以将第一层（16）沉积在基板（11）上，并且引入不同的工艺气体用于沉积 在第二室（30）中的连续低压辉光放电沉积工艺中的第二层（18）。 多个电极（60）和接地屏蔽（62）位于气门（34）的隔离通道（92）中。 电极（60）具有足以从任何一个沉积室逸出的任何气体分子产生等离子体的电位。 在形成等离子体之后，其被吸引并被捕获或镀在屏蔽件（62）上，防止气体等离子体着陆在基板材料（11）上或通过气体浇口。 本发明通过电离它们以形成等离子体并以永久的方式捕获等离子体离子来主动消除游离气体分子，从而减少气体通过气体门的反向扩散。
