I am making solar panels using ordinary inkjet printing methods. I need Silicon particles of Hydrogenated silicon for the Intrinsic layer of a PIN junction. The particles need to be 1um and will be dispersed in standard printing medium.
Dear Paul,
welcome,
There are more than one method to get hydrogenated nano silicon particles. But may be the most straight forward one is the synthesis of such material form the gas phase reaction where Colloidal particles of hydrogenated amorphous silicon (a-Si:H) are synthesized by decomposition of trisilane in supercritical n-hexane. You can get full description of the method by following the link: pubs.acs.org/doi/abs/10.1021/cm102486w

That method is very expensive, difficult, requires a lot of heating energy, needs very expensive and specialised equipment and is very dangerous. I was looking for a simple chemical reaction. I already have the amorphous silicon nano particles in powder form. I can also buy the silicon nano particles, suspended in solution, ready for printing in an inkjet printer, but without the Hydrogen bonding.
Example of what I need, would be exposing the silicon particles to hydrogen sulphide to give me sulphur doped Silicon. Is there an equally simple chemical reaction that would give me hydrogenated amorphous silicon? I want to keep well away from the dangerous silane and hexane.
