Description

technical field [0001] The invention relates to the technical field of thin-film solar cells, in particular to thin-film solar cells, components and manufacturing methods. Background technique [0002] Silicon-based thin film cells can be divided into PIN and NIP structures according to the growth sequence, but in order to obtain high conversion efficiency in applications, the P layer is usually used as a window layer through which sunlight enters the cell. Cells with a PIN structure are usually grown on a highly transparent ultra-white glass substrate, and can be patterned relatively easily by laser, so as to realize the series and parallel structures of cells to form components. However, the reflection of the glass interface in this structure causes about 8% of the incident light loss; on the other hand, during the growth process of the P / / I interface, it is difficult to control the contamination of the I layer by the dopant after the growth of the P layer. At present, th...
