Nyob rau hauv lub cheeb tsam ntawm lub zog tauj dua tshiab, nyias zaj duab xis photovoltaic (PV) tshuab tau tshwm sim los ua ib qho kev cog lus thev naus laus zis, muab ntau yam thiab muaj peev xwm mus kom ze rau kev tsim hluav taws xob hnub ci. Tsis zoo li cov pa hluav taws xob silicon-raws li hnub ci vaj huam sib luag, nyias zaj duab xis PV tshuab siv cov txheej txheem nyias nyias ntawm cov khoom siv semiconductor tso rau hauv cov txheej txheem hloov tau yooj yim, ua rau lawv hnav, hloov tau, thiab hloov tau rau ntau yam kev siv. Cov ntawv blog no delves rau hauv lub hauv paus ntawm nyias zaj duab xis PV tshuab, tshawb txog lawv cov khoom, kev ua haujlwm, thiab qhov zoo uas lawv coj mus rau lub zog tauj dua tshiab.
Cheebtsam ntawm nyias zaj duab xis PV Systems
Cov txheej txheem yees duab duab: Lub plawv ntawm cov duab ua yeeb yaj kiab nyias yog cov ntaub ntawv zoo li cadmium, tooj liab), tooj liab indium selicium selicium (a-si). Cov txheej no absorbs tshav ntuj thiab hloov mus rau hauv hluav taws xob hluav taws xob.
Substrate: Cov txheej txheej photoactive yog muab tso rau hauv lub substrate, uas muab kev txhawb nqa thiab hloov tau yooj yim. Cov khoom siv substrate muaj xws li iav, yas, lossis hlau foils.
Encapsulation: Txhawm rau tiv thaiv cov txheej txheem photoactive los ntawm ib puag ncig yam xws li ya raws thiab oxygen, nws yog encapsulated ntawm ob txheej tiv thaiv, feem ntau yog ua los ntawm polymers lossis iav.
Electrodes: Hluav taws xob tiv tauj, lossis electrodes, yog siv los sau cov hluav taws xob tsim los ntawm txheej txheej photoactive.
Confluence Box: Lub thawv confluence yog qhov chaw nruab nrab ntawm qhov chaw sib txuas, txuas rau tus kheej lub hnub ci modules thiab xa cov hluav taws xob tsim hluav taws xob rau lub inverter.
Inverter: Lub inverter hloov cov hluav taws xob ncaj qha (DC) hluav taws xob uas tsim los ntawm PV system rau hauv hluav taws xob hloov hluav taws xob (AC) hluav taws xob, uas yog sib xws nrog cov kab hluav taws xob thiab cov khoom siv hauv tsev feem ntau.
Kev ua haujlwm ntawm Thin Film PV Systems
Sunlight Absorption: Thaum tshav ntuj tawm tsam cov txheej txheem photoactive, photons (packets ntawm lub teeb lub zog) yog absorbed.
Electron Excitation: Cov photons absorbed excite electrons nyob rau hauv cov khoom siv photoactive, ua rau lawv dhia los ntawm lub zog qis zog mus rau lub zog siab dua.
Charge Separation: Qhov no excitation tsim ib tug imbalance ntawm tus nqi, nrog ntau tshaj electrons accumulating rau ib sab thiab electron qhov (tsis muaj electrons) nyob rau lwm yam.
Hluav taws xob tam sim no: Ua-nyob rau hauv hluav taws xob teb nyob rau hauv cov khoom siv photoactive coj cov electrons sib cais thiab qhov ntawm cov electrodes, tsim hluav taws xob tam sim no.
Qhov zoo ntawm Thin Film PV Systems
Lub teeb yuag thiab yoog raws: Nyias zaj duab xis PV tshuab yog qhov sib dua thiab hloov tau yooj yim dua li cov pa hluav taws xob silicon, ua rau lawv tsim nyog rau ntau yam kev siv, suav nrog ru tsev, tsev facades, thiab cov kev daws teeb meem ntawm lub zog.
Low-Light Performance: Nyias zaj duab xis PV systems yuav ua tau zoo dua nyob rau hauv lub teeb qis dua piv rau silicon panels, tsim hluav taws xob txawm nyob rau overcast hnub.
Scalability: Kev tsim cov txheej txheem ntawm nyias zaj duab xis PV tshuab yog scalable thiab adaptable rau huab hwm coj ntau lawm, muaj peev xwm txo nqi.
Ntau yam ntawm Cov Khoom Siv: Ntau yam ntawm cov khoom siv semiconductor siv hauv nyias zaj duab xis PV tshuab muaj peev xwm rau kev txhim kho ntxiv thiab txo nqi.

Nyias zaj duab xis PV tshuab tau hloov pauv lub hnub ci zog toj roob hauv pes, muab txoj hauv kev cog lus mus rau lub zog txuas ntxiv mus rau yav tom ntej. Lawv lub teeb yuag, hloov tau yooj yim, thiab yoog raws qhov xwm txheej, ua ke nrog lawv lub peev xwm rau cov nqi qis thiab txhim kho kev ua tau zoo hauv cov teeb pom kev qis, ua rau lawv xaiv qhov kev xaiv rau ntau yam kev siv. Raws li kev tshawb fawb thiab kev txhim kho txuas ntxiv mus, nyias zaj duab xis PV tshuab tau npaj los ua lub luag haujlwm tseem ceeb hauv kev ua kom tau raws li peb lub ntiaj teb kev xav tau ntawm lub zog nyob rau hauv ib puag ncig thiab lub luag haujlwm.
