Monocrystalline Silicon Thiab Polycrystalline Silicon

Cov tshuab hluav taws xob photovoltaic yog ib qho piv txwv ntawm lub zog ruaj khov thiab maj mam dhau los ua ib feem ntawm lub neej txhua hnub raws li ntau tus neeg hloov mus rau kev xaiv lub zog tauj dua tshiab. Xaiv cov khoom tsim nyog rau koj lub cell photovoltaic yog ib qho tseem ceeb ntawm cov txheej txheem thiab hnub no peb yuav los tshuaj xyuas qhov sib txawv tseem ceeb ntawm monocrystalline silicon thiab Polycrystalline silicon.

1.

Monocrystalline silicon

Monocrystalline silicon yog hu ua li ntawd vim hais tias nws yog tsim los ntawm ib tug tas mus li siv lead ua qauv thiab txoj kev uas nws tau raug tsim, nws tso cai rau ntws ntawm electrons tsis tsim kom muaj ntau yam kuj. Kev txiav txim atomic kev npaj ntawm monocrystalline silicon tau ua rau nws cov cell photovoltaic kom tswj tau lub zog hloov pauv ntau dua uas txawv ntawm li 15% - 24% ntawm qhov nruab nrab.

Polycrystalline Silicon

Ib leeg- siv lead ua silicon muaj lub sijhawm them rov qab ntawm ob xyoos uas ua tau zoo tshaj peb lub xyoo -cov cim qhia los ntawm ntau- siv lead ua silicon. Qhov kev soj ntsuam no yog ua raws li cov ntsiab lus tseem ceeb ntawm kev lag luam ncig.Ob daim ntawv ntawm silicon yuav tsim qee cov khoom pov tseg hluav taws xob, tab sis ib leeg -cov hlwb siv lead ua tsis tshua muaj kev rov ua dua tshiab vim lawv cov purity siab dua. Kwv yees li 95% tus nqi rov qab yog ua tiav nrog ib zaug -crystal silicon piv rau kwv yees li 85% ntawm ntau- siv lead ua silicon.

 

Koj tab tom txiav txim siab seb puas yuav siv monocrystalline lossis polycrystalline. Ob txoj kev xaiv no muaj lawv qhov zoo thiab qhov tsis zoo. Qhov kev xaiv boils mus rau qhov yuav ua rau koj lub hom phiaj zoo tshaj plaws. Yog tias koj xav tau kev ua haujlwm siab tshaj plaws thiab tsis xav siv qee cov nyiaj ntxiv, monocrystalline yog qhov kev xaiv ua. Txawm li cas los xij, yog tias koj xav tau ib qho kev xaiv uas yuav muaj tus nqi qis, ces polycrystalline yog lwm txoj hauv kev zoo.

Ob leeg monocrystalline thiab polycrystalline silicon yog cov khoom tseem ceeb ntawm hnub ci tshuab. Xaiv cov khoom tsim nyog qhia txog peb ob qho tib si

sib koom ntiaj teb thiab photovoltaic cell kev ua tau zoo.

1. Hnub Ci Rau Tsev
Monocrystalline panels ua haujlwm zoo rau cov ru tsev me. Piv txwv li, 5kW system xav tau txog 13 mono panels (es tsis yog yuav luag 17 polysilicon panels), uas txuag tau qhov chaw zoo.
Piv txwv li, Tesla's Solar Roof hauv California muab lub zog rau ntau lub tsev. Nws siv cov vuas monocrystalline thiab tsim cov khoom tsim tawm zoo. Nws ua rau cov tsev no muaj kev ywj pheej los ntawm txoj kab hluav taws xob.

2. Kev lag luam fais fab thiab thaj chaw deb
Polycrystalline panels muab lub zog rau telecom yees hauv Africa. Lub 100kW system nyob rau hauv Nigeria txiav qhov xav tau rau diesel heev. Qhov no txuag tau nyiaj zoo txhua lub hlis.
Hybrid systems, uas sib tov Monocrystalline panels thiab lithium roj teeb zoo li Tesla Powerwall, muaj ntau heev nyob rau hauv Australian cov tsev uas tsis nyob rau hauv daim phiaj. Lawv ua ke zoo hnub ci tso zis nrog kev siv roj teeb zoo.

1. Kev nce qib hauv Tech

Tib -Crystal Silicon Hloov:

N-Hom Silicon: Tshem tawm qhov tsis zoo ntawm boron thiab oxygen, uas ua rau nws ua haujlwm zoo dua. Cov kev sim kuaj pom tias nws tuaj yeem tsoo 26% kev ua haujlwm.
3D Designs: Muab cov hlwb tso rau saum ib leeg (xws li perovskite nrog silicon) tuaj yeem ua rau peb mus txog 35% kev ua haujlwm los ntawm 2030.
Ntau -Crystal Txhim Kho:

Unstable Multi-Crystals: Txoj kev tshiab ntawm kev ua cov no txiav rau ntawm cov npoo ntawm cov muaju, yog li lawv tau los ze zog mus rau 20% efficiency.

2. Kev txhawj xeeb ntsuab

Ib leeg- siv lead ua silicon muaj lub sijhawm them rov qab ntawm ob xyoos uas ua tau zoo tshaj peb lub xyoo -cov cim qhia los ntawm ntau- siv lead ua silicon. Qhov kev soj ntsuam no yog ua raws li cov ntsiab lus tseem ceeb ntawm kev lag luam ncig.

Ob daim ntawv ntawm silicon yuav tsim qee cov khoom pov tseg hluav taws xob, tab sis ib leeg -cov hlwb siv lead ua tsis tshua muaj kev rov ua dua tshiab vim lawv cov purity siab dua. Kwv yees li 95% tus nqi rov qab yog ua tiav nrog ib zaug -crystal silicon piv rau kwv yees li 85% ntawm ntau- siv lead ua silicon.
