Abstract
The invention relates to new type compound transparent conductive glass and a preparation method thereof. TiO2 and AZO films are deposited on an original transparent conductive glass through a magnetic control sputtering technique. The compound transparent conductive glass is applied to a solar front electrode, which can efficiently decrease the reflection of the incident lights on the TCO film and increase the luminous flux reaching to an active layer (silicon) so as to promote the solar cell Jsc, as well as efficiently prevent the hydrogen ion reduction of FTO under Plasma so as to decrease the serial resistors Rs of cells and promote FF in order to increase the efficiency of the cells.
Description
technical field [0001] The invention relates to the field of transparent conductive glass, in particular to the technical field of manufacturing novel composite transparent conductive glass. Background technique [0002] Transparent conductive glass is currently widely used as the front electrode of thin film solar cells due to its good conductivity and light transmission, such as figure 1 Shown. Fluorine-doped tin oxide (SnO 2 :F referred to as FTO) transparent conductive glass not only has good light transmittance and conductivity, but also has relatively mature industrialization technology, good thermal stability and high suede degree, so it has become the leading technology for thin film solar cells. Main products for electrode applications. [0003] For the silicon-based thin-film battery structure with glass as the substrate, in order to improve the efficiency of the battery, how to increase the luminous flux of the incident light reaching the active layer has become...
