Abstract
High quality silicon inks are used to form polycrystalline layers within thin film solar cells having a p-n junction. The particles deposited with the inks can be sintered to form the silicon film, which can be intrinsic films or doped films. The silicon inks can have a z-average secondary particle size of no more than about 250 nm as determined by dynamic light scattering on an ink sample diluted to 0.4 weight percent if initially having a greater concentration. In some embodiments, an intrinsic layer can be a composite of an amorphous silicon portion and a crystalline silicon portion.
