Imigaqo yelanga yelanga

Ilanga liyakhanya kwi-semiconductor pn junction, ndenze isibini esitsha se-elektroni. Phantsi kwesenzo secandelo lombane le-PN Junction, umngxunya uyaphuma kwingingqi ye-P ukuya kwingingqi, kwaye i-elektroni ihamba kwingingqi ye-N Ingingqi ukuya kwingingqi ye-N. Xa isekelo lixhunyiwe, kwangoku leweyo. Yindlela yeefolda zeforalip ye-solar esebenza ngayo.

Ukuveliswa kwamandla elanga Zimbini iintlobo zeSolar Swerha, enye yendlela yokuguqula-ubushushu-enye yimowudi yokuguqula umbane ekhawulezileyo.

. Ngokubanzi, amandla atshixiweyo atshintshwa abe ngumququ wendawo esebenzayo ngumqokeleli welanga ngumqokeleli welanga, kwaye emva koko i-turbine ye-Steam iqhutywa ukuvelisa umbane. Inkqubo yangaphambili yinkqubo yokuguqula yokukhanya; Inkqubo yokugqibela yinkqubo yokuguqula umbane.

(2) Iziphumo zefoto isetyenziselwa ukuguqula amandla elanga ngqo ngqo kumandla ombane. Isixhobo esisisiseko sefolda yeFowleyctric sisisele selanga. Iseli yelanga sisixhobo esiguqula ngokuthe ngqo amandla elanga ukuya kumandla ombane ngenxa yefuthe lokufota. Yifoto ye-semiconductor. Xa ilanga likhanya kwifoto, i-Photodiode iza kuguqula amandla elanga ibe ngamandla ombane kwaye ivelise kwangoku. Xa iiseli ezininzi ziqhagamshelwe kuchungechunge okanye ngokulinganayo, uluhlu lweeseli zelanga ezinamagunya amakhulu aphezulu anokwenziwa.

Okwangoku, i-crystalline silicon (kubandakanya i-Polysilicicicon kunye ne-monocrystalline) yeyona nto ibalulekileyo ye-fotovoltaic, isabelo sayo sentengiso singaphezulu kwe-90% ixesha elide liseza kuba zezona zinto ziphambili zeeseli zelanga.

Ixesha elide, itekhnoloji yemveliso yezixhobo zePolysilicon ilawulwa yimveliso eyi-10 yeenkampani ezi-7 kumazwe ama-3, enjenge-United States, eJapan naseMarikeni yeTekhnoloji.

I-Polysililicon ifuna ikakhulu ivela kwi-semicondors kunye neeseli zelanga. Ngokweemfuno ezahlukeneyo zokucoceka, zahlulwe ngokwamanqanaba elikwinqanaba le-elektroniki kunye nelanga. Phakathi kwabo, i-polysilicicon ye-polsililicon ye-elektroniki malunga ne-55% yenqanaba le-Polysilicon ye-Polysilicon ye-45%.

Ngophuhliso olukhawulezileyo lomzi-mveliso wefotovoltaic, ibango le-Polysilicicon kwiiseli zelanga likhula ngokukhawuleza kunokuphuhliswa kwe-polsililicon ye-Solar Polysilicon ngo-2008.

Ngo-1994, ukuveliswa ngokupheleleyo kweeseli zelanga emhlabeni kwakuyi-69mw kuphela, kodwa ngo-2004 yayikufuphi ne-1200mw, i-17mw yeminyaka eli-17. Iingcali ziqikelela ukuba ishishini le-Solar Photololtaic liya kugqitha kumandla enyukliya yenyukliya njengowona mthombo wamandla obalulekileyo kwisiqingatha sokuqala senkulungwane yama-21.
