I-Indium Tin Oxide (ITO) iyi-transparent conductive oxide (TCO) esetshenziswa kabanzi ehlanganisa kokubili ukuhanjiswa kukagesi okuphezulu kanye nokucaca okuhle kakhulu kokubona. Kubaluleke kakhulu kumaseli elanga e-crystalline silicon (c-Si), lapho idlala indima ebalulekile ekuthuthukiseni ukusebenza kahle kokuguqulwa kwamandla ngokusebenza njenge-electrode esobala noma isendlalelo sokuxhumana.
Kumaseli elanga e-crystalline e-silicon, i-ITO isetshenziswa ngokuyinhloko njengesendlalelo sokuxhumana sangaphambili ukuze kuqoqwe abathwali abakhiqiziwe kuyilapho kuvumela ukukhanya okuningi ngangokunokwenzeka ukuthi kudlule ungqimba lwe-silicon olusebenzayo. Lobu buchwepheshe buthole ukunakwa okubalulekile, ikakhulukazi ezinhlotsheni zamaseli ezisebenza kahle kakhulu njenge-heterojunction (HJT) namaseli elanga axhumene ngemuva.
| Umsebenzi | Umphumela |
|---|---|
| I-Electric Conductivity | Inikeza indlela yokumelana okuphansi ukuze ama-electron ahambe esuka kuseli aye kuyisekethe yangaphandle. |
| I-Optical Transparency | Ivumela ukudluliswa kokukhanya okuphezulu, ikakhulukazi ku-spectrum ebonakalayo, ikhulise inani lokukhanya okufinyelela ungqimba lwe-silicon. |
| I-Surface Passivation | Isiza ukunciphisa ukuhlangana kabusha kwendawo, ithuthukise ukusebenza kahle okuphelele kweseli yelanga. |
| Ukuqina Nokuqina | Ibonisa ukuzinza okuhle kakhulu kwemishini namakhemikhali, iqinisekisa isikhathi eside nokuthembeka kwamaseli elanga ngaphansi kwezimo zangaphandle. |
Izinzuzo ze-ITO Coating for Crystalline Silicon Solar Cells
Ukungafihli Okuphezulu:
I-ITO inokukhanyela okuphezulu ku-spectrum yokukhanya ebonakalayo (cishe i-85-90%), eqinisekisa ukuthi ukukhanya okwengeziwe kungamuncwa ungqimba lwe-silicon olungaphansi, ukuthuthukisa ukusebenza kahle kokuguqulwa kwamandla.
Ukungazweli Okuphansi:
I-ITO ihlinzeka ngokusebenza kahle kukagesi, iqinisekisa ukuqoqwa kwama-elekhtroni okuphumelelayo kusuka endaweni ye-silicon. Ukumelana kwayo okuphansi kuqinisekisa ukulahleka kwamandla okuncane ngenxa yongqimba lwangaphambili lokuxhumana.
Ukuzinza Kwekhemikhali Nokusebenza:
Izingubo ze-ITO zibonisa ukumelana okuhle kakhulu nokucekelwa phansi kwemvelo, njengokugqwala, futhi zizinzile ngaphansi kwamazinga okushisa aphezulu kanye nokuchayeka kwe-UV. Lokhu kubalulekile ezinsizeni zelanga okufanele zimelane nezimo ezinzima zangaphandle.
I-Surface Passivation:
I-ITO ingasiza futhi ukudlula ubuso be-silicon, yehlise ukuhlangana kabusha kwendawo futhi ithuthukise ukusebenza okuphelele kweseli lelanga.
