Mfundo za Panel Panel

Dzuwa limawalira pa Semiconductor Pn Contection, ndikupanga bad-elevetron. Pansi pa gawo lamagetsi yamagetsi a pn cholumikizira, bowo limatuluka kuchokera kudera la p kudera la N n dera, ndipo ma elekitoni amayenda kuchokera kudera la N Gdera. Gawo likalumikizidwa, zomwe zimapangidwa. Umu ndi momwe Photomelecric Soun cell amagwira ntchito.

Kuwongolera mphamvu m'badwo wa dzuwa kulimitundu iwiri ya m'badwo wa mphamvu zamagetsi, njira yosinthira-kutentha-magetsi, inayo ndiye njira yosinthira magetsi.

. Nthawi zambiri, mphamvu zotsekemera zimasinthidwa kukhala nthunzi ya sing'anga yogwira ntchito ndi dzuwa, kenako Turni Stebine imayendetsedwa kuti ipange magetsi. Njira yoyamba ndiyo njira yodzitchinjiriza; Njira yotsirizira ndi kutentha - njira yosinthira yamagetsi.

. Chipangizo choyambirira cha kutembenuka kwa potoelectric ndi khungu la dzuwa. Ma cell a dzuwa ndi chipangizo chomwe chimasinthiratu mphamvu kwambiri mphamvu yamagetsi chifukwa cha VoltCemion Ispor. Ndi semiconductormondode. Dzuwa likawala pa Photoodide, chithunzicho chimasinthira mphamvu yamagetsi yamagetsi kuti apange mphamvu yamagetsi ndikupanga zamakono. Maselo ambiri akalumikizidwa mu mndandanda kapena ofanana, maselo angapo a dzuwa ndi mphamvu yayikulu yomwe yatulutsa imatha kupangidwa.

Pakadali pano, silicon ya crystalline ndi polysilicon ndi monocrystalline zida zothandiza kwambiri, gawo lake lazipatso limakhala loposa 90%, ndipo mtsogolomo nthawi yayitali idzakhala zida zazikulu za maselo a dzuwa.

Kwa nthawi yayitali, matekinoloje opanga mapulogalamu a polysilicon amayendetsedwa ndi makampani okwanira 10 m'maiko atatu, monga United States, Japan ndi Germany, akupanga malo obisika.

Polysilicon amafuna makamaka kuchokera ku semicondectors ndi maselo a dzuwa. Malinga ndi zofunikira zosiyanasiyana zoyera, zogawidwa kukhala mulingo wamagetsi komanso kuchuluka kwa dzuwa. Pakati pawo, maakaunti a polysilicon a maakaunti pafupifupi 55%, maakaunti a dzuwa a polysilicon a 45%.

Ndi chitukuko chachangu cha makampani opanga zithunzi, kufunikira kwa polysilicon mu maselo a solar kukukula mwachangu kuposa kukula kwa Semonilinic polsicicon pofika 2008.

Mu 1994, kupanga konse kwa maselo a dzuwa padziko lapansi kunali 69mw okha, koma mu 2004 anali pafupi ndi 1200mw, kuwonjezeka kwa zaka 10 zokha. Akatswiri akuneneratu kuti makampani ogulitsa a Sunvovoltaltaltaltaltar amapitilira mphamvu ya nyukiliya ngati imodzi mwamagetsi ofunikira kwambiri m'zaka za m'ma 2000 zino.
