Indium Tin Oxide (ITO) ndi yogwiritsidwa ntchito kwambiri transparent conductive oxide (TCO) yomwe imaphatikiza madulidwe apamwamba amagetsi komanso kuwonekera bwino kwambiri. Ndikofunikira kwambiri m'maselo a dzuwa a crystalline silicon (c-Si), komwe amagwira ntchito yofunika kwambiri pakuwongolera mphamvu ya kutembenuka kwamphamvu mwa kukhala ngati electrode yowonekera kapena wosanjikiza wolumikizana.
M'maselo a solar a crystalline silicon solar, zokutira za ITO zimagwiritsidwa ntchito makamaka ngati gawo lakutsogolo kuti asonkhanitse zonyamulira zomwe zimapangidwa ndikulola kuwala kochuluka momwe kungathekere kupita kugawo logwira ntchito la silicon. Ukadaulo uwu wapeza chidwi chachikulu, makamaka pamitundu yogwira ntchito kwambiri yamagulu monga heterojunction (HJT) ndi ma cell a solar olumikizana kumbuyo.
| Ntchito | Zotsatira |
|---|---|
| Mayendedwe Amagetsi | Amapereka njira yotsika yokana kuti ma electron ayende kuchokera ku selo kupita ku dera lakunja. |
| Optical Transparency | Amalola kufalikira kwakukulu kwa kuwala, makamaka mu mawonekedwe owoneka bwino, kukulitsa kuchuluka kwa kuwala komwe kumafika pa silicon wosanjikiza. |
| Surface Passivation | Imathandizira kuchepetsa kuyanjananso kwapadziko lonse, kumapangitsa kuti ma cell a solar azigwira bwino ntchito. |
| Kukhazikika ndi Kukhazikika | Imawonetsa kukhazikika kwamakina ndi mankhwala, kuonetsetsa kuti moyo wautali ndi wodalirika wa ma cell a dzuwa pansi pazikhalidwe zakunja. |
Ubwino wa ITO Coating for Crystalline Silicon Solar Cells
Kuwonekera Kwambiri:
ITO imakhala yowonekera kwambiri mu kuwala kowoneka bwino (kuzungulira 85-90%), zomwe zimatsimikizira kuti kuwala kowonjezereka kungathe kuyamwa ndi silicon wosanjikiza wapansi, kupititsa patsogolo mphamvu yotembenuza mphamvu.
Low Resistivity:
ITO imapereka mphamvu yabwino yamagetsi, kuwonetsetsa kuti ma elekitironi atolere bwino kuchokera pamwamba pa silicon. Resistivity yake yotsika imatsimikizira kutaya mphamvu kochepa chifukwa cha kusanjikiza kutsogolo.
Kukhazikika kwa Chemical ndi Mechanical:
Zovala za ITO zimawonetsa kukana kwambiri kuwonongeka kwa chilengedwe, monga dzimbiri, ndipo ndizokhazikika pansi pa kutentha kwambiri komanso kuwonekera kwa UV. Izi ndizofunikira kwambiri pamapulogalamu a solar omwe amayenera kupirira zovuta zakunja.
Surface Passivation:
ITO imathanso kuthandizira kupitilira pamwamba pa silicon, kuchepetsa kuphatikizika kwamadzi ndikuwongolera magwiridwe antchito a cell solar.
