Zuva rinopenya pane semiconductor PN junction, richigadzira gomba idzva-electron pair.Pasi pechiito chemunda wemagetsi wePN junction, gomba rinoyerera kubva munharaunda yeP kusvika kuN nharaunda, uye electron inoyerera kubva munharaunda yeN kusvika kuP.Apo dunhu rakabatanidzwa, ikozvino inoumbwa.Ndiwo mashandiro anoita photoelectric effect solar masero anoshanda.
Kugadzirwa kwesimba rezuva Kune marudzi maviri emagetsi ezuva, imwe ndiyo nzira yekushandura chiedza-kupisa-magetsi, imwe ndiyo nzira yekushandura chiedza-magetsi.
(1) Nzira yekushandura chiedza-kupisa-magetsi inoshandisa simba rinopisa rinogadzirwa nemwaranzi yezuva kugadzira magetsi.Kazhinji, simba rinopisa rinoshandiswa rinoshandurwa kuita chiutsi chesvikiro rekushanda nemuunganidzi wezuva, uye ipapo turbine yemhepo inofambiswa kugadzira magetsi.Nzira yekare ndiyo nzira yekushandura chiedza-kupisa;Nzira yekupedzisira ndiyo kupisa - magetsi ekushandura nzira.
(2) Iyo photoelectric mhedzisiro inoshandiswa kushandura solar radiation simba rakananga musimba remagetsi.Iyo yakakosha mudziyo weiyo photoelectric shanduko ndiyo solar cell.Solar cell chishandiso chinoshandura zvakananga simba rechiedza rezuva kuita simba remagetsi nekuda kweiyo photogeneration volt athari.Iyo semiconductor photodiode.Kana zuva richipenya paphotodiode, iyo photodiode inoshandura simba rechiedza chezuva kuita simba remagetsi uye kugadzira ikozvino.Kana maseru akawanda akabatana munhevedzano kana kuti akatevedzana, sikweya mitsara yemaseru ezuva ane simba rakakura rekubuda anogona kuumbwa.
Parizvino, crystalline silicon (kusanganisira polysilicon uye monocrystalline silicon) ndiyo inonyanya kukosha photovoltaic zvinhu, mugove wayo wemusika unopfuura 90%, uye mune ramangwana kwenguva yakareba icharamba iine zvinhu zvakakosha zvemasero ezuva.
Kwenguva yakareba, tekinoroji yekugadzira yepolysilicon zvinhu yakadzorwa nemafekitori gumi emakambani manomwe munyika dze3, dzakadai seUnited States, Japan neGermany, vachigadzira blockade yetekinoroji uye kutengeserana kwemusika.
Polysilicon inoda kunyanya inobva ku semiconductors uye masero ezuva.Zvinoenderana neyakasiyana kuchena zvinodiwa, yakakamurwa kuita yemagetsi level uye solar level.Pakati pavo, yemagetsi-giredhi polysilicon accounts inosvika makumi mashanu neshanu muzana, solar level polysilicon account ye45%.
Nekukurumidza KUDZIDZWA KWE PHOTOVOLTAIC indasitiri, kudiwa kwepolysilicon mumasero ezuva kuri kukura nekukurumidza kupfuura kugadzirwa kwe semiconductor polysilicon, uye zvinotarisirwa kuti kudiwa kwesolar polysilicon kuchapfuura kwemagetsi-giredhi polysilicon panosvika 2008.
Muna 1994, kugadzirwa kwakazara kwemasero ezuva munyika kwaingova 69MW, asi muna 2004 kwaive pedyo ne1200MW, kuwedzera kakapetwa ka17 mumakore gumi chete.Nyanzvi dzinofanotaura kuti indasitiri ye solar photovoltaic ichapfuura simba renyukireya seimwe yeanonyanya kukosha masosi emagetsi muhafu yekutanga yezana ramakore re21.
