Cov Ntsiab Cai ntawm Kev Hloov Kho Hnub Ci

Saj zawg zog solar cell yog ib hom nyias zaj duab xis hnub ci cell, uas muaj kev siv tshuab siab heev, kev ua tau zoo heev, tsis tshua muaj nqi thiab dav siv. Nws tuaj yeem siv rau cov hnab ev ntawv hnub ci, hnub ci hloov pauv, hnub ci teeb nyem, hnub ci tsheb, hnub ci nkoj nkoj, thiab txawm tias lub dav hlau hnub ci. Ib qho tseem ceeb ntawm daim ntawv thov kev hloov pauv hnub ci zog yog BIPV (Lub Tsev Sib Koom Tes Photovoltaic), uas tuaj yeem ua ke rau hauv qhov rais lossis ru tsev, phab ntsa sab nrauv, lossis phab ntsa sab hauv.
Roj teeb txoj cai
Cov teebmeem photoelectric tuaj yeem tshwm sim thaum lub teeb ultraviolet yog irradiated ntawm cov hlau nto. Raws li Einstein xaus lus, dawb electrons yog generated vim hais tias lub photon zog ntawm teeb meem teeb pom kev zoo yog ntau dua lub binding zog ntawm electrons. Lub luag haujlwm ntawm lub hnub ci hlwb yog hloov lub hnub ci rau hauv qhov hluav taws xob thiab tam sim no, uas yog kev hloov pauv photoelectric.
Qhov ua tau zoo ntawm cov nyhuv photovoltaic yog ntau dua li cov nyhuv photoelectric. Vim hais tias nyob rau hauv lub hnub ci hlwb qhov twg cov teebmeem photovoltaic tshwm sim, ob hom semiconductors nrog opposite polarity tsim ib tug pn hlws ris, tsim ib tug built-in hluav taws xob teb uas tsav electrons mus rau hauv lub Circuit Court, tsim voltage thiab tam sim no nyob rau hauv lub Circuit Court.
