Hauv photocell thaum Lub teeb tawm tsam cov khoom siv semiconductor, lub semiconductor ua rau cov electrons ntws ki tsim hluav taws xob . Hnub ci zog tsim cov tshuab siv lub tswv yim ntawm kev hloov lub teeb zog in hluav taws xob zog. Yog li ib photocell hloov teeb zog rau hauv hluav taws xob zog.
Yog li ntawd, lub teeb yuav hloov mus rau hauv hluav taws xob li cas?
Hnub ci-powered photovoltaic (PV) panels hloov lub hnub rays rau hauv hluav taws xob los ntawm exciting electrons nyob rau hauv silicon hlwb siv photons ntawm teeb los ntawm lub hnub. Qhov no hluav taws xob tau ces yuav siv rau muab lub zog tauj dua tshiab rau koj lub tsev lossis kev lag luam.
Ib tug kuj yuav nug, ua li cas lub photovoltaic cell hloov lub teeb rau hluav taws xob? Hnub ci PV cell tsim hluav taws xob los ntawm absorbing tshav ntuj thiab siv qhov ntawd teeb lub zog los tsim hluav taws xob tam sim no. Muaj ntau photovoltaic cell nyob rau hauv ib lub hnub ci vaj huam sib luag, thiab tam sim no tsim los ntawm tag nrho cov hlwb ua ke ntxiv kom txaus hluav taws xob pab txhawb koj lub tsev.
Ib yam li ntawd, ib yam khoom uas hloov lub teeb lub zog rau hauv hluav taws xob yog dab tsi?
Teb: Cov ntaus ntawv uas yog siv hloov ' lub teeb zog 'to' hluav taws xob zog ' yog hu ua photovoltaic cell. Nqe lus piav qhia: Nws yog semiconductor diode uas tuaj yeem ua tau hloov 'pom teeb rau hauv direct tam sim no'. Lawv yog tsim los ntawm 'silicon cells' npaj los tsim cov block loj uas tsim lub hnub ci vaj huam sib luag.
Koj hloov hluav taws xob li cas?
Ib hluav taws xob generator yog ib qho khoom siv uas hloov lub zog rau hauv hluav taws xob . Cov tshuab hluav taws xob ua haujlwm vim muaj kev sib raug zoo ntawm cov hlau nplaum thiab hluav taws xob . Generators uas hloov kinetic (mechanical) zog rau hauv hluav taws xob zog tsim ze li ntawm tag nrho cov hluav taws xob uas cov neeg siv khoom siv.

Tus nqi hluav taws xob hluav taws xob ntau npaum li cas hauv UK?
Tus nqi hluav taws xob hluav taws xob ntau npaum li cas hauv UK? Teb: Geothermal cov lus nug hauv UK feem ntau xa mus rau hauv av qhov cua sov. Cov tshuab hluav taws xob hauv av no raug nqi nruab nrab ntawm £ 10,000 txog £ 20,000 los yuav thiab nruab. Cov tswv tsev tseem yuav tsum suav rau cov nqi kev pabcuam txhua xyoo, uas tuaj yeem nyob ib puag ncig £ 300
Dab tsi yog kev siv hluav taws xob Yuav ua li cas kev lag luam tsim ntau hom kev siv hluav taws xob?
Kev siv hluav taws xob yog hais txog tus nqi lossis txiaj ntsig uas tus neeg siv khoom tau txais los ntawm kev sib pauv, raws li University of Delaware. Muaj plaub hom kev siv: daim ntawv, qhov chaw, sijhawm thiab muaj; ua ke, lawv pab tsim cov neeg siv khoom txaus siab
Lub teeb hluav taws xob puas tuaj yeem ua rau hluav taws kub?
Tab sis thaum tsis txhim kho kom zoo, cov teeb pom kev zoo recessed tuaj yeem overheat. Yog tias lawv cov kub sab nraud mus dhau 194 degrees Fahrenheit (90 degrees Celsius), hluav taws tuaj yeem tshwm sim. Qhov no feem ntau yog vim cov xaim tsis zoo lossis cov khoom sib txuas nrog cov khoom siv hluav taws xob lossis cov rwb thaiv tsev
Nws raug nqi npaum li cas los tsim lub tshuab hluav taws xob hluav taws xob?
International Renewable Energy Agency (IRENA) tshaj tawm cov nqi peev nyiaj nruab nrab rau cov chaw tsim hluav taws xob loj loj nrog cov chaw cia khoom feem ntau los ntawm qis li $ 1,050 / kW mus txog li $ 7,650 / kW, thaum qhov ntau ntawm cov phiaj xwm me me yog nyob nruab nrab ntawm $ 1,300 / kW thiab $ 8,000 / kW
Lub tshuab hluav taws xob ntau npaum li cas ua lub tshuab hluav taws xob tsim?
Cov tswv yim chav turbines tuaj nyob rau hauv tag nrho cov duab thiab qhov ntau thiab tsawg thiab tsim hluav taws xob xws li ib los yog ob megawatts (kwv yees cov zis tib yam li ib qho cua turbine) txog li 1,000 megawatts los yog ntau tshaj (cov zis tawm los ntawm lub tshuab fais fab loj, sib npaug rau 500-1000 cua. turbines ua haujlwm tag nrho)
