AI Customer ServiceIn recent years, iron sulfide (FeS 2), otherwise known as pyrite, has received some attention as a possible candidate for thin-film photovoltaic applications.
AI Customer ServiceThe strategy adopted here is to develop a solar cell where the high light absorbing FeS2 (a = 6 105 cm-1) absorbs the visible light and injects the electrons into the conduction band of the large gap TiO2 (or other oxides: e.g. ZnO, WO3) thus generating a photovoltage.
Pyrite ( Eg =0.95 eV) is being developed as a solar energy material due to its environmental compatibility and its very high light absorption coefficient. A compilationof material, electronic and interfacial chemical properties is presented, which is considered relevant for quantum energy conversion.
The element zinc can be incorporated in FeS2 (pyrite) in concentrations of up to 4500 p,g/g. A. Ennaoui et al. / Iron disulfide for solar energy conc'ersion 319 We assume that Zn2+ substitutes for Fe2+ because ZnS2 crystallizes in the pyrite structure. Its influence on conductivity, even at this high concentration, is small (section 3.1.1).
The most interesting aspect of this study is the use of pyrite as an ultrathin (10–20 nm) layer sandwiched between large gap p-type and n-type materials in a p-i-n like structure. Such a system, in which the pyrite layer only acts as photon absorber and mediates injection of excited electrons can be defined as sensitization solar cell.
The energy converting structures are 10,000 times thinner than the structure of a silicon solar cell and the plant can afford to throw them away every year. In contrast, solar cells not only have to be synthesized at very high tempera- tures, they need years to recover the energy needed for their synthesis.
For FeS2 (pyrite) the value of u equals 0.386. Other minerals are also summa- rized in table 2 . Iron disulfide FeS2 can also crystallize in the marcasite structure, an or- thorhombic modification (space group Pnmm ) which is present in nature. Marcasite was synthesized as thin films (see section 2.1.4).
