METTALIC DISPERSION AND FORMATION OF COMPOUND FILM FOR PHOTOVOLTAIC DEVICE ACTIVE LAYER |
摘要 |
A compound film may be formed by formulating a mixture of elemental nanoparticles composed of the IB, the IIIA, and, optionally, the VIA group of elements having a controlled overall composition. The nanoparticle mixture is combined with a suspension of nanoglobules of gallium to form a dispersion. The dispersion may be deposited onto a substrate to form a layer on the substrate. The layer may then be reacted in a suitable atmosphere to form the compound film. The compound film may be used as a light-absorbing layer in a photovoltaic device. Optionally, the compound film for an active layer of a photovoltaic device may be formed in two or more sub-layers. A first sub-layer having a first component of the active layer may be formed on a substrate with a first process. A second sub-layer including a second component of the active layer may then be formed using a second process such that the first sublayer is disposed between the second sub-layer and the substrate. The second component may have a different chemical composition than the first component. The first and/or second sub-layer may comprise one or more components in the form of particles and/or globules. This procedure may be repeated any number of times for any number of sub-layers so that active layer can be built up sequentially. The different chemical compositions of the components in the sub-layers can provide the active layer with a graded bandgap. |
