Tam sim no, hnub ci txoj kev teeb tau teeb tsa hauv ntau lub nroog thiab txawm tias txoj kev nyob deb nroog hauv kuv lub tebchaws. Raws li hom tshiab ntawm txoj kev teeb uas txuag hluav taws xob, lub hnub ci txoj kev teeb pom kev zoo tau txais kev pom zoo los ntawm cov tib neeg, thiab lub xeev kuj tau nqis peev ntau cov neeg ua haujlwm thiab cov khoom siv los txhawb qhov no. Yog li ntawd lub hnub ci txoj kev teeb muaj lub sij hawm ntev - thiab kev loj hlob zoo, yog li dab tsi yog qhov kev ua tau zoo uas cuam tshuam rau lub hnub ci txoj kev teeb roj teeb module?
(1) luv Circuit Court tam sim no (Isc)
When the solar cell is placed under the illumination of a standard light source and the output end of the solar cell module is short-circuited, the current flowing through both ends of the solar cell is the short-circuit current of the cell module. The method of measuring the short-circuit current is to connect the two ends of the solar cell with an ammeter whose internal resistance is less than 1Ω. The short-circuit current varies with the light intensity.
(2) Peak tam sim no (Im)
Lub ncov tam sim no tseem hu ua qhov siab tshaj plaws ua haujlwm tam sim no lossis qhov ua haujlwm zoo tshaj plaws tam sim no. Lub ncov tam sim no hais txog qhov ua haujlwm tam sim no thaum lub hnub ci cell module tso tawm lub zog siab tshaj plaws, thiab chav tsev ntawm lub ncov tam sim no yog A.
(3) Peak voltage (Um)
Lub ncov voltage tseem hu ua qhov siab tshaj plaws ua haujlwm voltage lossis qhov zoo tshaj plaws ua haujlwm voltage. Lub ncov voltage yog hais txog qhov ua hauj lwm voltage thaum lub hnub ci cell outputs lub siab tshaj plaws hwj chim, thiab chav tsev ntawm lub ncov voltage yog V. Lub ncov voltage ntawm lub module nws txawv nrog rau qhov nce los yog txo ntawm cov cell nyob rau hauv series. Lub ncov voltage ntawm lub module nrog 36 hlwb nyob rau hauv series yog 17-17.5V.
(4) Qhib Circuit Court voltage (Uoc)
Nyob rau hauv lub illumination ntawm lub teeb qhov chaw, thaum ob qho tag nrho qhib (qhov zoo thiab tsis zoo ncej ntawm lub hnub ci cell module tsis txuas nrog lub load), cov zis voltage ntawm lub hnub ci cell yog qhib - Circuit Court voltage. Chav tsev ntawm qhov qhib hluav taws xob hluav taws xob yog V. Qhov qhib hluav taws xob hluav taws xob ntawm lub hnub ci hluav taws xob hloov pauv nrog qhov nce lossis txo ntawm cov xov tooj ntawm tes hauv series. Qhov qhib Circuit Court voltage ntawm ib module nrog 36 hlwb nyob rau hauv series yog hais txog 21V. Qhov qhib hluav taws xob hluav taws xob ntawm lub roj teeb tuaj yeem ntsuas nrog lub siab sab hauv DC millivoltmeter.
(5) Cov zis siab tshaj plaws
Yog hais tias qhov kev xaiv load kuj muaj peev xwm ua kom cov khoom ntawm cov zis voltage thiab tam sim no, lub siab tshaj plaws tso zis hwj chim yuav tau, uas yog sawv cev los ntawm lub cim Pm. Qhov ua haujlwm voltage thiab ua hauj lwm tam sim no yog hu ua qhov zoo tshaj plaws ua hauj lwm voltage thiab optimum ua hauj lwm tam sim no, uas yog sawv cev los ntawm cov cim Um thiab Im feem, Pm =UmIm
Cov khoom ntawm qhov ntsuas hluav taws xob thiab ntsuas tam sim no yog ntsuas lub zog. Lub zog tso zis tso zis yog qhov tso zis ntau tshaj plaws nyob rau hauv ib txwm muaj ( tuaj yeem ua haujlwm ntev). Qhov ntsuas tso zis hluav taws xob ntawm lub hnub ci cell muaj feem cuam tshuam rau kev hloov pauv kev ua haujlwm. Feem ntau hais lus, qhov siab dua qhov kev hloov pauv ntawm lub roj teeb module ib cheeb tsam, qhov ntau dua qhov tso zis zog. Tam sim no kev hloov dua siab tshiab ntawm lub hnub ci hlwb feem ntau yog nyob nruab nrab ntawm 14 feem pua thiab 17 feem pua. Lub zog tso zis ntawm txhua square centimeter ntawm cov hlwb yog 14 txog 16mW, thiab cov zis hluav taws xob ntawm lub hnub ci cell modules ib square meter yog li 120W.
(6) Lub zog siab (Pm)
Peak power is also called maximum output power or optimum output power. Peak power refers to the maximum output power of the solar cell module under normal working or test conditions, that is, the product of the peak current and the peak voltage: Pn=ImUm. The unit of peak power is watts. The peak power of a solar cell module depends on the solar irradiance, the solar spectral distribution and the operating temperature of the module, so the measurement of the solar cell module should be carried out under standard conditions. The test standard of solar cells: the spectral distribution when the air quality is AM1.5 (for specific regulations, please refer to the relevant national and international standards in my country), the solar radiation emitted by humans is 1000W/m², and the temperature is 25 degree . The output power of the solar cell under this condition is defined as the peak power of the solar cell.
(7) Fill factor (ff)
Nws hais txog qhov sib piv ntawm lub zog siab tshaj plaws ntawm lub hnub ci module rau cov khoom ntawm qhov qhib -circuit voltage thiab luv-circuit tam sim no: f=Pm/(IsU.) . Nws qhia txog cov yam ntxwv sib txawv ntawm qhov tso zis hluav taws xob ntawm lub roj teeb nrog cov khoom thauj, thiab cov khoom ntim puv yog ib qho tseem ceeb ntawm cov yam ntxwv ntawm qhov zoo thiab qhov tsis zoo ntawm lub hnub ci. Qhov loj dua qhov ua tau zoo, qhov ua tau zoo ntawm lub hnub ci cell.
