Service Life Of Solar Panels

Lub neej kev pab cuam ntawm lub hnub ci vaj huam sib luag yog txiav txim siab los ntawm cov ntaub ntawv ntawm cov panels, tempered iav, EVA, TPT, thiab lwm yam. Feem ntau, lub neej kev pab cuam ntawm lub hnub ci vaj huam sib luag tsim los ntawm cov tuam txhab uas siv cov ntaub ntawv zoo dua tuaj yeem ncav cuag 25 xyoo, tab sis nrog cov kev pab cuam lub neej. ib puag ncig, cov ntaub ntawv ntawm lub hnub ci vaj huam sib luag yuav muaj hnub nyoog dhau sijhawm. Feem ntau, lub zog yuav raug txo los ntawm 30 feem pua ​​​​tom qab 20 xyoo ntawm kev siv, thiab 70 feem pua ​​​​tom qab 25 xyoo siv.
Slicing, tu, npaj suede, peripheral etching, tshem tawm ntawm PN ntxiv rau junctions nyob rau tom qab, fabrication ntawm sab sauv thiab sab electrodes, fabrication ntawm antireflection films, sintering, kuaj thiab grading yog 10 kauj ruam.
Cov lus qhia tshwj xeeb ntawm kev tsim khoom rau hnub ci hlwb
(1) Slicing: Siv ntau cov hlau txiav, silicon pas nrig yog txiav rau hauv square silicon wafers.
(2) Kev Tu: Ntxuav cov silicon wafer siv cov txheej txheem tu, thiab tom qab ntawd tshem tawm cov txheej puas ntawm cov silicon wafer los ntawm 30-50 um siv cov kua qaub (lossis alkali) tov.
(3) Kev npaj ntawm qhov chaw ntxhib los mos: Anisotropic etching ntawm silicon wafer nrog cov tshuaj alkali yog siv los npaj ib qho kev ntxhib los mos ntawm qhov chaw ntawm silicon wafer.
(4) Phosphorus diffusion: Siv cov txheej txheej (los yog cov kua dej, los yog cov khoom phosphorus nitride daim ntawv qhov chaw) rau diffusion, ib tug PN ntxiv junction yog tsim, nrog ib tug junction qhov tob feem ntau ntawm 0.3 rau {{ 3}.5 ua.
(5) Peripheral etching: Lub diffusion txheej tsim nyob rau hauv peripheral nto ntawm silicon wafer thaum lub sij hawm diffusion yuav luv luv-circuited lub sab sauv thiab sab electrodes ntawm lub roj teeb, thiab lub peripheral diffusion txheej yuav raug tshem tawm los ntawm masking ntub etching los yog plasma qhuav etching.
(6) Tshem tawm lub nraub qaum PN ntxiv rau pob. Kev ntub dej los yog sib tsoo feem ntau yog siv los tshem tawm PN ntxiv rau kev sib tshuam ntawm sab nraub qaum.
(7) Fabrication ntawm sab sauv thiab qis electrodes: Siv lub tshuab nqus tsev vaporation plating, electroless npib tsib xee plating, los yog txhuas paste luam ntawv thiab sintering txheej txheem. Ua ntej, ua rau qis electrode, thiab tom qab ntawd ua rau sab sauv electrode. Aluminium paste luam ntawv yog ib txoj kev siv dav dav.
(8) Ua cov yeeb yaj kiab antireflection: Txhawm rau txo qhov poob ntawm qhov kev xav tau, ib txheej ntawm cov yeeb yaj kiab antireflection yuav tsum tau them rau saum npoo ntawm silicon wafer. Cov ntaub ntawv siv los tsim cov yeeb yaj kiab antireflection muaj xws li MgF2, SiO2, Al2O3, SiO, Si3N4, TiO2, Ta2O5, thiab lwm yam. Cov txheej txheem txheej txheem tuaj yeem yog lub tshuab nqus tsev, txheej txheej txheej ion, txheej txheem sputtering, txheej txheem luam ntawv, PECVD txoj kev, los yog txau txoj kev.
(9) Sintering: Sintering ib lub roj teeb nti mus rau ib tug npib tsib xee los yog tooj liab substrate.
(10) Test classifications: Raws li cov kev qhia tshwj xeeb, kev ntsuas kev faib tawm.
