Kev siv cov photoelectric nyhuv - qhov txhia chaw thiab ib tug ntau ntawm

Lub photoelectric nyhuv yog ib tug tshwm sim ntawm tus sis ntawm lub teeb nrog teeb meem, nyob rau hauv lub teeb zog yog absorbed thiab generated hluav taws xob tam sim no. Yog hais tias qhov no yog raug mus rau lub teeb generated los ntawm cov electron mus tshaj lub cev lub cev, ces muaj yog ib tug sab nraud photoelectric nyhuv, yog tias sab hauv, thiab ua rau ib tug kev hloov nyob rau hauv lub conductivity ntawm cov khoom - sab hauv.

Tswv yim siv ntawm qhov photoelectric nyhuv nyob rau hauv lub kos duab tej zaum yuav varied. Nyob rau hauv kev, cov sab nraud photoelectric nyhuv yog siv rau lub suab tu tub tu kiv, piv txwv li, nyob rau hauv ib tug yeeb yam. Tsis tas li ntawd, teem tshwj xeeb cov khoom ntsuas cov brightness, luminous siv, illuminance. Photoelectric nyhuv muab kev koom tes nyob rau hauv cov txheej txheem kev tswj. Rau lub hom phiaj no muaj tshwj xeeb pab kiag li lawm hu ua hnub ci hlwb.

Photocells thiab lawv daim ntawv thov yog raws li nyob rau hauv lub fact tias cov kev hloov nyob rau hauv conductivity nrog illumination. Nyob rau hauv kev, xws ntsiab yog siv los tswj thiab accounting tshuab, piv txwv li, suav cov khoom tiav. Lwm yam Tso - ntog khoom tswj nyob rau hauv lub txwv cheeb tsam. Yog hais tias tus neeg tsav tsheb presses ib txhais tes nkag mus rau cov ua hauj lwm cheeb tsam, cov xovxwm nres sai li sai tau. Qhov no txhais ib photocell. Cov tib ntaus ntawv yog muab tso rau hauv lub yav tas los raug nplua lub turnstile nyob rau hauv lub subway: yog hais tias cov nyiaj them yog nqa tawm (cov photocell yog xiam oob qhab), cov zaj yog qhib, yog hais tias tsis (tus photocell yog enabled), nws yog kaw.

Kev txhim kho cua pa luam yeeb kuj ua lub photocell pib ntsais koj teeb ib tug tseem ceeb heev qhov teeb meem no. Kev siv cov photovoltaic hlwb nyob rau hauv cov zauv tshuab tau tso cai kom ua tau ntau dua cov neeg machining ntawm qhov chaw.

Lwm cov tseem yog kev siv ntawm cov photoelectric nyhuv raws li ib tug tam sim no qhov twg los, los yog hnub ci hlwb. Nyob rau hauv cov pab kiag li lawm ua hauj lwm yog raws li nyob rau hauv ib tug ntau yam ntawm Internal photoelectric nyhuv, hu ua brushless photoelectric nyhuv. Nyob rau hauv cov ntaub ntawv no, Yog hais tias lub teeb nkag mus rau lub hu ntawm ob semiconductors tshwm sim EMF, uas nws yog ua tau qhov ncaj hloov dua siab tshiab ntawm lub teeb rau hauv hluav taws xob lub zog.

Tej hnub ci hlwb yog ua los ntawm gallium arsenide tebchaw. Lawv cia koj yuav tau txais hluav taws xob tsis tas yuav ua tej kev puas tsuaj - lub hnub illuminates tus nto ntawm lub roj teeb thiab cov zis yog npaj txhij rau kev noj. Yog tsis muaj nyuab txhua yam pab kiag li lawm, muaj yog tsis muaj yuav tsum tau mus hlawv cov roj los yog los mus tsim haib lub pas dej tauv.

Txawm li cas los, xws kev siv ntawm lub photoelectric nyhuv yog txuam tam sim no nrog loj teeb meem. Firstly, ua hnub ci txoj kev panels thiab, raws li, yog ib txoj kev mus hluav taws xob. Secondly, qhov efficiency ntawm no hloov dua siab tshiab tsis pub tshaj 26%. Txawm li cas los, ua hauj lwm ntawm ua lub efficiency thiab txo tus nqi ntawm converting lub teeb flux yuav mus nyob rau, thiab nws yog vam hais tias tsis ntev nws yuav tau npaj txhij heev npaum thiab pheej yig solar panels.

Tom qab tag nrho, txawm tam sim no yuav chaw noj muab hluav taws xob solar panels. Txawm nyob rau hauv qhov chaw nyob qhov twg muaj ib tug ntau ntawm tshav ntuj hnub thoob plaws hauv lub xyoo, cov converters ua hauj lwm. Zeem muag rau kev siv ntawm cov hnub ci zog yog txaus nyiam heev. Sim kawm ua pov thawj tias lub zog ntawm lub hnub tso cai rau kom yaj hlau. Thiab yog hais tias peb nco qab cov lus dab neeg uas cov ancient Greek paub txog Archimedes siv tsom iav tau siv lub hnub ci hlawv Roman ships, muaj tsis muaj tsis ntseeg nyob rau hauv lub unlimited possibilities ntawm kev siv ntawm lub teeb raws li ib tug lub zog qhov chaw.

Cov cuav deals nrog rau daim ntawv thov ntawm cov photoelectric nyhuv, lub mechanism ntawm nws keeb kwm thiab hom. Piv txwv ntawm kev siv tswv yim ntawm cov phenomenon ntawm lub photoelectric nyhuv nyob rau hauv cov kos duab.
