Passivation of trap states in polycrystalline Si by cyanide treatments

The cyanide treatment in which polycrystalline Si is immersed in a KCN solution followed by rinsing in boiling water increases the energy conversion efficiency of 〈ITO/silicon oxide/polycrystalline Si〉 junction solar cells to 12.5%. The XPS measurements under bias show that the trap density in polyc...
