Kev Xaiv Ntawm Daim phiaj Txuas Txuas Hluav Taws Xob Hluav Taws Xob

Tom qab qhov kev siv ntawm cov phiajcim txuas nrog lub zog tsim hluav taws xob, nws pib nkag mus rau theem tsim thiab kev siv. Kev tsim ntawm daim phiaj txuas hluav taws xob tsim hluav taws xob tso rau pem hauv ntej cov kev xav tau siab dua rau kev tswj hwm tus nqi. Tam sim no, muaj ob txoj hauv kev rau tus nqi thiab kev ua haujlwm ntawm daim phiaj txuas hluav taws xob tsim hluav taws xob. Ib qho yog ib qho kev ua tau zoo ntawm cov kab ntau lawm uas siv cov khoom siv hluav taws xob siab kom txo tau kev txhawb nqa thiab cov nqi zog; Lwm qhov kev xaiv yog overwire modules, nce qhov sib piv ntawm cov modules thiab inverters, ua kom cov zis ntau tshaj inverter, thiab txo tus nqi ntawm inverter, AC cables, tis txee, thiab cov kauj ruam-up transformers. Ob qho kev xaiv muaj lawv tus kheej zoo, tab sis lawv tsis paub meej thiab yuav tsum tau txiav txim siab, ua tib zoo xam, thiab pom qhov nyiaj tshuav nyiaj li cas. Daim phiaj txuas nrog lub tshuab hluav taws xob photovoltaic, yog tias tib lub zog tivthaiv thiab lwm yam kev mob zoo ib yam, lub zog tsim tau zoo ib yam, Tab sis yog tias tib tus naj npawb ntawm cov modules tau nruab rau hauv tib cheeb tsam, siv tsis muaj txiaj ntsig 250W lossis tsis muaj txiaj ntsig 3W, tus nqi pem hauv ntej ntawm cov khoom siv. , lub hauv paus, cables, kev ua haujlwm, thiab lwm yam hauv qhov system yog tib yam. Yog li ntawd, qhov nruab nrab cov peev txheej ntawm cov khoom siv tau zoo yuav qis dua qhov nruab nrab ntawm cov peev txheej ntawm cov khoom siv tsis zoo. Ntxiv rau cov nqi pib, cov khoom siv tau zoo tuaj yeem txo cov nqi av.

Nrog rau kev txhim kho ntawm cov roj teeb efficiency, cov kev xav tau ntawm cov khoom zoo, kev ua tau zoo, cov khoom raug, thiab cov cuab yeej siv rau kev sib txuas ntawm cov hluav taws xob photovoltaic tau nce ntau, uas yuav ua rau muaj kev tsim cov nqi tsim khoom. Yog li ntawd, tus nqi ntawm high-efficiency modules yog siab dua li cov tsoos modules. Txhawm rau kom paub meej txog qhov cuam tshuam ntawm kev ua haujlwm siab ntawm cov cuab yeej siv thev naus laus zis ntawm tus nqi hluav taws xob ib kilowatt teev, qhov rhiab heev ntawm lub zog nce thiab cov nqi module hloov mus rau kilowatt teev nqi tau ntsuas.

Cov Ntsiab Cai ntawm Grid Connected Power Generation System

Yog hais tias lub teeb yog irradiated ntawm lub hnub ci cell, nws yog absorbed ntawm lub interface txheej, thiab photons uas muaj zog txaus yuav excite electrons los ntawm covalent bonds nyob rau hauv P-hom silicon thiab N-hom silicon. Ua ntej recombination, electrons thiab qhov nyob ze ntawm lub interface yuav raug sib cais los ntawm qhov hluav taws xob ntawm qhov chaw them nqi, thiab electrons yuav txav mus rau qhov zoo nqi N cheeb tsam, thaum lub qhov yuav txav mus rau qhov tsis zoo nqi P cheeb tsam.

Los ntawm kev sib cais tus nqi ntawm txheej txheej interface, ib qho kev ntsuas sab nraud yog tsim los ntawm thaj tsam P thiab N. Lub sijhawm no, electrodes tuaj yeem ntxiv rau ntawm ob sab ntawm silicon wafer thiab txuas nrog lub voltmeter. Rau crystalline silicon hnub ci hlwb, qhov qhib hluav taws xob hluav taws xob yog 0.5-0.6V. Qhov ntau electron qhov khub yog generated los ntawm lub teeb nyob rau hauv lub interface txheej, qhov ntau dua tam sim no, thiab lub teeb ntau zog yog absorbed los ntawm lub interface txheej, uas ua rau ib tug loj cheeb tsam ntawm lub interface txheej, piv txwv li lub roj teeb, qhov ntau dua qhov tam sim no generated. nyob rau hauv lub hnub ci cell.

Muaj ob txoj hauv kev rau kab sib txuas hluav taws xob tsim hluav taws xob, ib qho yog photothermal hloov dua siab tshiab thiab lwm qhov yog kev hloov pauv hluav taws xob ncaj qha.
