Hnub ci vaj huam sib luag tau txais pheej yig dua, cov qauv ntawm tes tshiab puas cuam tshuam rau lub neej ntev?

Lub hnub ci tshuab thev naus laus zis tau hloov kho tas li nyob rau xyoo dhau los, nrog kev hloov pauv kev ua tau zoo nce xyoo ib xyoos, tab sis cov nqi tseem poob qis - qhov no puas yuav cuam tshuam rau lub hnub ci vaj huam sib luag? Raws li tsib xyoos ntawm kev sim los ntawm ib lub chaw soj nstuam uas yog US Department of Energy, kev kwv yees kwv yees tias cov hnub ci tshiab yuav tseem tsim tau 80 feem pua ​​​​ntawm lawv lub zog pib tom qab 30 xyoo ntawm kev siv.

US Department of Energy's Sandia National Laboratories (SNL) tau pib kawm tsib xyoos ntawm kev degradation ntawm hnub ci modules, yuav 23 lub hnub ci sib txawv los ntawm xya lub tuam txhab hauv peb qhov kev nyab xeeb thiab thaum kawg kawm txog kev ua tau zoo ntawm tag nrho 834 hnub ci vaj huam sib luag uas muaj tau nruab.

Hnub ci cell hom tau hloov pauv ntau nyob rau xyoo tas los no, nrog cov khoom siv txhuas-txhim kho qhov chaw (Al-BSF) tsim ua lag luam nyob rau hauv 2018 nrog 90 feem pua, thiab maj mam ua lag luam xim hloov mus rau cell designs xws li PERL, PERT, SHJ los yog TOPCon tom qab xyoo 2020, tsab ntawv ceeb toom sau tseg qhov tsis muaj cov ntaub ntawv mus sij hawm ntev ntawm cov tshiab hnub ci cell thiab module technologies.

Pab pawg thawj coj Marios Theristis kuj tau taw qhia tias lub hnub ci kev lag luam hloov pauv sai thiab tsis muaj cov ntaub ntawv mus sij hawm ntev ntawm cov thev naus laus zis tshiab, nws tsis tuaj yeem teb cov lus nug txog kev ua haujlwm ntev ntawm lub hnub ci vaj huam sib luag, yog li pab pawg yuav thiab tshuaj xyuas cov khoom lag luam hnub ci ncaj qha. . Pab neeg no thiaj li yuav thiab tshuaj xyuas cov khoom lag luam muaj hnub ci ncaj qha thiab thaum kawg ua cov ntaub ntawv tshaj tawm rau pej xeem ntawm qhov tsis qhia npe. Pab neeg no kuj tau ua haujlwm nrog National Renewable Energy Laboratory (NREL) thiab University of Central Florida (UCF) txhawm rau txhim kho tib lub tshuab hauv cov huab cua sib txawv.

Pab neeg no tau ua cov kev sim hauv New Mexico, Colorado thiab Florida, sim qhov kev ua tau zoo thiab pib lub zog ruaj khov ntawm lub hnub ci vaj huam sib luag raws li cov txheej txheem thaum pib ntawm kev sim thiab ib ntus nyob rau tsib xyoos tom ntej los saib xyuas kev degradation.

Lawv pom tias qhov degradation tus nqi dhau lub sij hawm yog cov tsis-linear, thiab cov hnub ci module hom, txawm hais tias lub caij hloov pauv, zoo ib yam li yav dhau los modules, nrog qhov nruab nrab degradation tus nqi ntawm ib ncig ntawm -0.6 feem pua ​​​​ntawm ib xyoos, thiab uas tawm ntawm tag nrho ntawm 23 lub hnub ci sib txawv tau kawm, rau qhov muaj qhov degradation siab tshaj qhov kev lees paub txwv thiab 13 tau pom tias muaj peev xwm ua tau ntau tshaj li 30-xyoo lub neej (yog tias qib degradation ruaj khov). Lub peev xwm yuav dhau 30 xyoo (yog tias kev puas tsuaj ruaj khov) tau pom los ntawm 13 lub hnub ci.

Raws li tus naj npawb ntawm kev teeb tsa lub hnub ci nce ntxiv, cov neeg siv khoom thiab cov neeg koom nrog yuav xav paub seb qhov ua haujlwm ntev ntawm lub hnub ci vaj huam sib luag yog zoo ib yam nyob rau hauv lub ntsej muag ntawm kev hloov pauv ntawm lub hnub ci tshuab hluav taws xob thiab txo cov nqi sai, Theristis ntseeg tias cov txiaj ntsig tau zoo, tab sis kuj tau taw qhia. tias 26 feem pua ​​​​ntawm lub hnub ci yuav zoo tshaj qhov kev tiv thaiv kev txwv, thiab tias tus nqi degradation yuav tsum raug txo kom txog rau thaum lub neej ntawm cov vaj huam sib luag tuaj yeem txuas ntxiv mus.

Zuag qhia tag nrho, lub hnub ci degradation tus nqi tsis zoo li tau cuam tshuam, txawm tias tus nqi poob qis hauv kaum xyoo dhau los.
