There are efforts to replace the classical transparent conducting coating, Indium Tin Oxide (ITO), (or other TCOs) by a new class of materials which are easier to handle and cheaper in mass production. Transparent conductive coatings are produced which consist of polymers or carbon nanotubes (CNT). In this investigation poly(3,4-ethylenedioxythiophene) :poly (styrene sulfonate) (PEDOT:PSS) and not...
A novel approach for heterojunction silicon wafer solar cell fabrication is being investigated: This approach features nanocomposite plasma deposited amorphous silicon suboxides (a-SiOx:H) for high-quality surface passivation combined with overlaying plasma deposited doped microcrystalline silicon (μc-Si:H(p+)/μc-Si:H(n+)) for use as heterojunction emitter and back-surface-field. Special attention...
In this work, a novel approach for heterojunction solar cell fabrication, featuring plasma deposited amorphous silicon sub-oxides (a-SiOx:H) for high quality surface passivation combined with plasma deposited doped microcrystalline silicon (?c-Si(n+/p+)) is used to form the heterojunction. Special attention is paid (i) to the front and back surface passivation of the bulk material by high-quality...
The electrical properties of various lead-free electrically conductive adhesives are investigated. They are intended to replace the solder, which is normally used to connect the interconnector tapes to the busbar. Compared to solder joints conductive adhesives offer the advantage of lower contact formation temperature with reasonable low contact resistances.
At the moment there are efforts to replace the classical transparent conducting coating, Indium Tin Oxide, (or other TCO's) by a new class of materials, which are easier to handle and cheaper in mass production. Possible choices are transparent conductive coatings, which consist of polymers. In this investigation PEDOT:PSS is used. Carbon nanotubes are added in order to render the film electrically...
