PHOTOVOLTAIC CELL

光伏电池

Résumé

A photovoltaic cell comprises a first layer of a first absorber material (1) comprising a front face, a rear face on which first contact electrodes having first polarity (101) are interdigitated with the second contact electrodes having second polarity (102), a second layer of a second absorber material (2), above the first layer, comprising a front face, of third contact electrodes having second polarity (203) being placed on the front face of the second layer, the first and second semiconductor materials having electron affinities and bandgap widths such that the carriers having the first polarity pass between the first and second layer and are collected from the first and second layers by the first electrodes (101), the carriers of second polarity are collected from the first layer by the second electrodes (102), and the carriers of second polarity are collected from the second layer by the third electrodes (203).
一种光伏电池,包括:第一吸收体材料(1)的第一层,第一层包括前表面和背面,在背面上第一接触电极(101)具有第一极性并且与具有第二极性的第二接触电极(102)相间错杂;位于第一层的上方的第二吸收体材料(2)的第二层,第二层包括前表面,第三接触电极(203)具有第二极性并设置在第二层的前表面上,第一和第二半导体材料具有的电子亲和性和带隙宽度使得具有第一极性的载流子在第一层和第二层之间传输并由第一电极(101)从第一和第二层中收集,第二电极(102)从第一层收集具有第二极性的载流子,并且第三电极(103)从第二层收集具有第二极性的载流子。
