Ib txoj hauv kev los txhim kho kev ua haujlwm ntawm silicon solar cells

Cov kws tshawb fawb ntawm Australian National University tau pom ib txoj hauv kev los txhim kho kev ua haujlwm ntawm silicon solar cells (PV). Qhov no yog ua tiav los ntawm kev ntxiv 'passivation contact' ntawm cov hlau thiab silicon Cheebtsam ntawm lub hnub ci cell, ua rau nws tsim tau ntau dua.

Nrog rau Australian National University kev tshawb fawb txo cov kev txwv tam sim no ntawm cov hnub ci vaj huam sib luag, kev ua tau zoo ntawm cov hnub ci vaj huam sib luag yuav nce ntxiv.

Tus kws tshawb fawb txog qhov project: "Cov kev tshawb pom no yuav pab thawb kev ua haujlwm ntawm silicon solar cells ze rau lawv qhov kev txwv theoretical."

Lub hnub ci hlwb yog cov khoom siv uas hloov lub teeb lub zog hauv daim ntawv ntawm photons rau hauv lub zog hluav taws xob. Raws li nws sawv, lub hnub ci hlwb tsis tuaj yeem ua haujlwm ntawm lub peev xwm siab tshaj plaws vim tias qhov hluav taws xob loj loj los ntawm kev sib cuag ncaj qha ntawm cov hlau thiab silicon.

"Kev hloov pauv hlau oxides, xws li titanium oxide, muaj ntau yam khoom uas ua rau lawv zoo tagnrho li cov khaubncaws sab nraud povtseg," cov kws tshawb fawb piav qhia. "Qhov no tsis yog lub tswv yim tshiab, tab sis txoj kev uas peb muab cov khaubncaws sab nraud povtseg ua tau zoo dua thiab ua haujlwm siab dua li txhua yam uas tau tshaj tawm yav dhau los."

Pab neeg tshawb fawb vam tias yuav tsim cov thev naus laus zis no mus rau qhov chaw uas nws tuaj yeem siv tau rau ntawm qhov loj hauv kev lag luam hnub ci.

Silicon solar cells suav txog kwv yees li 95 feem pua ​​​​ntawm tag nrho cov hnub ci kev lag luam. Muab lawv cov khoom muaj txiaj ntsig zoo dua lawv cov neeg sib tw, lawv yuav tsum nyob twj ywm tseem ceeb rau yav tom ntej.

Cov kws tshawb fawb tau hais tias, "Yog tias ua tiav, peb tuaj yeem pom peb cov thev naus laus zis hauv yuav luag txhua lub hnub ci vaj huam sib luag tshiab tau nruab rau saum lub ru tsev lossis hauv cov chaw siv hluav taws xob hnub ci hluav taws xob."

Ib tug xov tooj ntawm cov tswv yim teeb meem yuav tsum tau daws ua ntej lub tshuab yuav siv tau, tab sis lub PV zej zog twb ua hauj lwm los daws cov teeb meem no.

Kev ua haujlwm ntawm lub hnub ci zog yuav ua kom muaj zog huv dua ntawm tus nqi qis dua. Qhov no tsis yog tsuas yog pab tiv thaiv kev hloov pauv huab cua xwb, tab sis kuj tseem qhib txoj hauv kev tshiab kev lag luam rau lub zog siv hluav taws xob uas tsis muaj nqi.
