Indium Tin Oxide (ITO) yog siv dav siv pob tshab conductive oxide (TCO) uas ua ke ob qho tib si hluav taws xob hluav taws xob thiab kev pom pom zoo heev. Nws yog ib qho tseem ceeb tshwj xeeb tshaj yog nyob rau hauv crystalline silicon (c-Si) hnub ci hlwb, qhov uas nws ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm ntawm lub zog hloov pauv los ntawm kev ua haujlwm zoo li pob tshab electrode lossis txheej tiv tauj.
Nyob rau hauv crystalline silicon hnub ci hlwb, ITO txheej yog tsuas yog siv raws li pem hauv ntej kev sib cuag txheej los sau cov generated cab kuj thaum tso cai ntau li ntau tau mus rau lub active silicon txheej. Cov thev naus laus zis no tau txais kev saib xyuas tseem ceeb, tshwj xeeb tshaj yog rau cov xov tooj ntawm tes uas muaj txiaj ntsig zoo xws li heterojunction (HJT) thiab rov qab hu rau hnub ci hlwb.
| Muaj nuj nqi | nyhuv |
|---|---|
| Hluav taws xob conductivity | Muab txoj hauv kev uas tsis tshua muaj siab rau cov hluav taws xob los ntawm lub cell mus rau sab nraud Circuit Court. |
| Optical Transparency | Tso cai rau kev sib kis ntawm lub teeb siab, tshwj xeeb tshaj yog nyob rau hauv qhov pom spectrum, ua kom lub teeb pom kev zoo mus txog cov txheej silicon. |
| Nto Passivation | Pab txo qhov chaw recombination, txhim khu kev ua tau zoo tag nrho ntawm lub hnub ci cell. |
| Durability thiab Stability | Exhibits zoo heev mechanical thiab tshuaj stability, ua kom lub neej ntev thiab kev cia siab ntawm lub hnub ci hlwb nyob rau hauv sab nraum zoov tej yam kev mob. |
Qhov zoo ntawm ITO Txheej rau Crystalline Silicon Solar Cells
High Transparency:
ITO muaj cov pob tshab siab hauv qhov pom lub teeb pom kev zoo (nyob ib puag ncig 85-90%), uas ua kom lub teeb ntau tuaj yeem nqus tau los ntawm cov txheej txheem silicon, txhim kho lub zog hloov pauv.
Tsawg Resistivity:
ITO muaj cov khoom siv hluav taws xob zoo, ua kom cov khoom siv hluav taws xob zoo los ntawm silicon nto. Nws tsis tshua muaj resistivity ua kom tsawg zog poob vim rau pem hauv ntej kev sib cuag txheej.
Chemical thiab Mechanical Stability:
ITO coatings muaj kev tiv thaiv zoo rau ib puag ncig degradation, xws li corrosion, thiab ruaj khov nyob rau hauv qhov kub thiab txias thiab UV raug. Qhov no yog qhov tseem ceeb heev rau kev siv hnub ci uas yuav tsum tau tiv taus qhov hnyav sab nraum zoov.
Nto Passivation:
ITO tseem tuaj yeem pab passivate saum npoo ntawm silicon, txo cov nplaim recombination thiab txhim kho tag nrho kev ua haujlwm ntawm lub hnub ci cell.
