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).
