Heterojunction nrog Intrinsic Thin-txheej |
HJT thev naus laus zis muaj qhov sib luag ntawm cov qauv ntawm tes bifacial, kev ua haujlwm siab thiab tsis tshua muaj lub teeb attenuation yam ntxwv. Kev ua haujlwm loj ntawm cov khoom siv feem ntau yog siab dua 24%, thiab xav tias yuav tsum tau nce ntxiv mus rau saum 30%. Nws tsis muaj teeb meem LID thiab PID, tsis tshua muaj kub coefficient, siab bifaciality thiab lub teeb tsis muaj zog zoo. | HJT roj teeb xav tau cov cuab yeej siv nyiaj siab thiab cov nqi siv nyiaj siab, tab sis raws li cov txheej txheem matures thiab dhau los ua hauv zos, cov nqi yuav tsum pheej yig dua. | HJT theoretical efficiency txwv, tab sis nws cov txheej txheem kev lag luam tseem nrawm dua thiab nws tseem tsis tau dhau los ua tus thawj coj ua lag luam. | HJT roj teeb xav tau cov cuab yeej siv nyiaj siab thiab cov nqi siv nyiaj siab, tab sis cov nqi yuav tsum poob raws li thev naus laus zis nce qib thiab dhau los hauv cheeb tsam. | HJT hlwb muaj kev cia siab rau yav tom ntej hauv kev lag luam photovoltaic vim lawv qhov zoo xws li kev ua haujlwm siab thiab qis kub coefficient, tab sis lawv cov kev lag luam tam sim no kuj me me. |

Interdigitated Back Contact |
IBC thev naus laus zis tshem tawm qhov nqus thiab thaiv ntawm lub teeb los ntawm pem hauv ntej electrode los ntawm kev tsim tag nrho cov electrode tiv tauj rau sab nraum qab ntawm lub roj teeb, yog li txhim kho lub photoelectric conversion efficiency ntawm lub roj teeb. Nws muaj ntau dua roj teeb efficiency thiab zoo dua aesthetic tsim. | Cov txheej txheem ntawm IBC roj teeb yog qhov nyuaj, nyuaj thiab kim dua, yog li nws nyuaj rau kev tsim khoom loj hauv lub sijhawm luv. Txawm li cas los xij, nws muaj peev xwm nyob rau hauv cov txheej txheem superposition, xws li kev sib txuas nrog HJT los tsim HBC roj teeb, uas tuaj yeem txhim kho kev ua tau zoo. | IBC thev naus laus zis yog hom N-hom roj teeb uas muaj peev xwm ua tau zoo, tab sis tam sim no nws yog qhov nyuaj rau kev tsim khoom loj thiab yuav tsum muaj kev siv thev naus laus zis ntxiv thiab txo nqi. | Cov txheej txheem nyuaj ntawm IBC roj teeb ua rau lawv cov nqi siab, tab sis nyob rau hauv ntev, lawv muaj peev xwm nyob rau hauv superposition txheej txheem thiab tej zaum yuav ua ke nrog technologies xws li HJT los tsim tau ntau npaum li cas roj teeb. | IBC roj teeb feem ntau siv nyob rau hauv high-end kev lag luam vim lawv cov kev ua tau zoo thiab zoo nkauj, tab sis tsis muaj ntau lub tuam txhab tam sim no nqis peev rau lawv, feem ntau vim tias cov txheej txheem nyuaj thiab tus nqi siab. |
Txhua lub tshuab muaj nws qhov tshwj xeeb daim ntawv thov scenarios thiab cov txiaj ntsig tseem ceeb. Kev xaiv ntawm txoj kev siv thev naus laus zis muaj txiaj ntsig cuam tshuam rau qib kev txaus siab ntawm kev xav tau ntawm kev lag luam, kev xav txog kev siv nyiaj txiag zoo, thiab kev xav txog kev loj hlob ntawm technology. Nyob rau hauv tam sim no photovoltaic teb, txawm hais tias PERC hlwb tseem nyob hauv kev lag luam loj vim lawv qhov zoo yav dhau los, nrog rau cov kev hloov pauv sai hauv cov thev naus laus zis, lawv tau maj mam hloov los ntawm N-hom xov tooj ntawm tes thev naus laus zis, kos npe rau iteration tshiab ntawm photovoltaic thev naus laus zis.
