SOLAR CELL BUILT AROUND p-TYPE HETEROSTRUCTURE OF AMORPHOUS AND NANOCRYSTALLINE SILICON NITRIDE - SILICON

摘要

FIELD: physics.SUBSTANCE: single junction solar cell comprises p-silicon substrate of p-type Si(100) pretreated HF acid. Substrate top surface is provided with the ply of 4-5 nm deep n-type film of amorphous silicon nitride mixed with silicon nitride of nanocrystalline structure applied by magnetron sputtering in argon from solid-state SiNtarget. Electric contacts are produced by magnetron sputtering. Note here that contacts on element top side are made of Ag and shaped to a comb. Note also that rear electric contact on Si(100) substrate back is made of Ag or Cu.EFFECT: higher efficiency without application of whatever extra plies and solar power concentrators.9 dwg
