1. Uburyo bwo gukoresha imiti igabanya ubukana bwa laser ya SE
Intego:Uburyo bwo gukoresha laser ya Selective Emitter (SE) bwongera urwego rwa emitter ku ngirabuzimafatizo ya TOPCon yo mu bwoko bwa N kugira ngo bigabanye ubushobozi bwo guhangana n'ibintu no kunoza imikorere y'impinduka.
Uburyo:Ingufu za laser zishongesha ubuso bwa silikoni, bigatuma atome za boron (B) ziri mu kirahuri cya borosilicate zikwirakwira vuba muri silikoni, bigatuma habaho urwego runini rw’ingufu. Gukoresha doping nyinshi ahantu hahurira bigabanya ubudahangarwa bw’ingufu, mu gihe gukoresha doping yoroheje ahandi bigabanya igihombo cyo gusubiranamo, amaherezo bikanoza imikorere ku kigero cya 0.2%-0.4%.
2. Ikorwa rya Tunnel Oxide na Polycrystalline Silicon Layers
Intego:Izi ngingo ziri inyuma ya silicon wafer zikora imiterere y’aho zihurira, ingenzi mu kugabanya gusubiranamo no kongera imikorere myiza.
Uburyo:Uburyo bwo gusiga umwuka wa Plasma Enhanced Chemical Vapor Deposition (PECVD) bukoreshwa mu nganda bushyiramo filime ya silicon oxide ya 1-2nm n'urwego rwa silicon rudafite ibara rya 100-150nm, ruhinduka icyuma mu gihe cyo gukurura kugira ngo rukore urwego rwa polycrystalline. PECVD itanga umuvuduko wo hejuru wo gushyiramo umwuka, igabanya umwanda, kandi ihendutse, bigatuma iba amahitamo meza yo gukora ibintu byinshi.
3. Ingufu zirinda kugarura urumuri (ARC)
Intego:Imiterere ya dielectric ifite urwego rwinshi (SiOx/SiONx/SiNx) igabanya igihombo cy’urumuri kandi ikongera ubushobozi bwo kwinjiza urumuri, yongera ubwiza bw’amashanyarazi n’ubushobozi.
Izindi nyungu:ARC itanga uburyo bwo kunyura hejuru y’ubuso binyuze mu kugabanya igipimo cyo gusubiranamo kw’ubuso, kongera igihe cy’ubuzima bw’uturemangingo, no kurinda ibice byari byarashyizwemo mbere (nk’alumina imbere) kwangirika no kwanduzwa.
4. Gutera hakoreshejwe laser (LIF)
Intego:LIF ikoreshwa mu gucapa nyuma ya ecran kugira ngo yoroshye uburyo bwo guhuza icyuma na silikoni. Ubu buryo bwongera ubushobozi bwo guhuza icyuma no kugabanya ubushobozi bwo guhuza icyuma, bigatuma ingufu z'amashanyarazi zisohoka neza.
Ingaruka:LIF byagaragaye ko yongera ubushobozi bwo guhindura ibicuruzwa ku kigero cya 0.2% cyangwa kirenga, ibi bikaba ari inyongera y'agaciro mu nganda za TOPCon.
Izi ntambwe z'ingenzi mu mikorere zigaragaza ubuhanga buhanitse mu gukora mu ikoranabuhanga rya TOPCon, bigatuma habaho imikorere myiza no kunoza imikorere y'uturemangingo tw'izuba.
