Hnub Ci Inverter 1Kw

Gallium arsenide (GaAs) boasts qhov kev ua tau zoo tshaj plaws ntawm cov khoom siv photovoltaic, ncav cuag 28.8 feem pua. Qhov no yog vim GaAs muaj qhov sib txawv ntawm qhov ncaj thiab zoo dua ntawm 1.43 eV - ua rau kev nqus tau zoo dua nrog cov txheej nyias nyias thiab txo qis zog. Tsis tas li ntawd, GaAs muaj cov khoom siv hluav taws xob zoo tshaj plaws rau silicon. Txawm li cas los xij, nws kim heev los tsim vim nws xav tau cov khoom siv purity siab, uas feem ntau txwv nws mus rau qhov chaw siv (xws li satellites thiab rovers).

Cadmium Telluride

Cadmium telluride (CdTe) yog ib qho kev ua tau zoo ntawm cov yeeb yaj kiab photovoltaic uas tau ua tiav ntawm 22.1 feem pua. CdTe muaj qhov sib txawv zoo sib xws rau GaAs ntawm 1.44 eV, muab qhov zoo ib yam li pom hauv GaAs - kev nqus tau zoo hauv cov yeeb yaj kiab nyias thiab tsawg photon zog poob. Cov khoom siv no kuj khav theeb qhov ua tau yooj yim, tus nqi qis heev, thiab nws tau tsim cov hnub ci kev lag luam uas pheej yig dua silicon nrog lub sijhawm luv zog them rov qab (txawm tias muaj kev ua haujlwm qis dua). Txawm hais tias cov txiaj ntsig zoo li no, muaj qee qhov teeb meem - cadmium muaj tshuaj lom thiab tellurium tsawg heev, ua rau lub sijhawm ntev ntawm cov thev naus laus zis no tsis paub meej rau tam sim no.

Tooj liab Indium Gallium Selenide

Copper indium gallium selenide (CIGS) tau ua tiav qhov kev ua yeeb yam zoo sib xws rau CdTe li, nrog rau qhov siab tshaj ntawm 22.6 feem pua. Lub compound muaj cov tshuaj formula CuInxGa(1-x)Se2 qhov twg x tuaj yeem coj tus nqi ntawm 0 thiab 1. Qhov kev hloov pauv ntawm cov qauv tshuaj no ua rau cov kab sib txawv ntawm cov khoom sib txawv ntawm 1. 0 eV (x=1, ntshiab tooj liab indium selenide) thiab 1.7 eV (x=0, ntshiab tooj liab gallium selenide). Txawm li cas los xij, zoo li GaAs hlwb, CIGS yog kim los tsim thiab ua rau lub hnub ci vaj huam sib luag uas tsis tuaj yeem sib tw nrog cov khoom lag luam tam sim no. Tsis tas li ntawd, zoo li tellurium, indium yog qhov tsawg heev, txwv lub peev xwm mus sij hawm ntev ntawm cov thev naus laus zis no.
