| dc.description | The solar cell call “STIMULATED INVERSION LAYER SOLAR CELL (SIL)” is made of a Transparent Conductive Oxide (TCO), silicon rich oxide and silicon, and it has three possibilities of generate electrical energy from Sun light. The first one is through an inversion layer produced by charging the SRO. This concept has been proved experimentally. The second one takes advantage of the nanocrystals produced in the solar cell, there are some papers that shows that photovoltaics effects are observed in SRO [1, 2, 3] [4]. The third possibility is if we can use the TCO as a semiconductor and add the energy generated by this layer to that of the silicon solar cell. This will be equivalent to a tandem solar cell. There are many reports that uses TCO to form semiconductor-insulator-semiconductor (SIS) heterojunction solar cells. So, for this analysis it is assumed that TCO, and in particular the Zinc Oxide doped with Aluminum (AZO), behave as a semiconductor, in the same way that silicon does. AZO is the TCO used for this analysis, but any other that complains with the requisites of transparency and electric conductivity can be used.
The objective of this analysis is to find out the conditions in which both semiconductors AZO and silicon are in the depletion regimen, in such a way that in they both the charge separation take place. The Zinc Oxide band gap has been reported in the literature as 3.3 eV and the affinity 4.5 eV [5], and it is N type. So, it is adequate to propose that in AZO the ZnO band gap is constant, and the Fermi level varies with the Al doping. A big variation of the fermi level has been also reported for AZO [4, 5, 6 and 7], so in this analysis we suppose that the Fermi varies under the conduction band. | |
