The production process is simple, can in the preparation of amorphous silicon thin film and pin structure. 2). Continuous, large area, automated batch production. 3). The amorphous silicon solar battery substrate can be glass, stainless steel and so on, so the cost is small. 4.) can be designed into a variety of forms, the use of an integrated structure, can obtain higher output voltage and the photoelectric conversion efficiency. 5). The film material is obtained by glow discharge SiH4 silane decomposition, the low price of raw materials. The structure, principle and method of preparation of amorphous silicon solar cell 1. The amorphous silicon solar cell is a substrate with glass, stainless steel and special plastic structure, as shown in figure 1. In order to reduce the series resistance, usually with laser TCO film, amorphous silicon (A-si) film and aluminum (Al) film electrode were cut into strips, as shown in figure 2. Based on the international standard with a width of about 1cm, called a sub cell, with internal connection of each sub cell together, so the output current integrated battery current for each sub cell, the total output voltage of each battery voltage. In practical application, choice of structure and area of battery according to the needs of current and voltage, made of amorphous silicon solar cell. The working principle of the 1.1 principle of amorphous silicon solar cell is based on the photovoltaic effect of semiconductor. When the
