Melemo le melemo ea lisele tsa letsatsi tse tšesaane tsa filimi

Lisele tsa letsatsi tse tšesaane li sebelisoa haholo libakeng tsa limela tsa temo tsa photovoltaic le lisebelisoa tsa photovoltaic tse hlokang phetisetso ea leseli. Na ua tseba hore na ke melemo efe le melemo ea lisele tsa letsatsi tse tšesaane tsa filimi? Phanele ee e tšesaane ea letsatsi e nka lilemo tse kae?

Hajoale, lisele tsa letsatsi tse teng tse tšesaane li kenyelletsa haholo-holo: lisele tsa letsatsi tsa cadmium telluride tse tšesaane tsa filimi ea "copper indium gallium selenide" le lisele tsa letsatsi tsa amorphous silicon tse tšesaane.

1. Melemo ea lisele tsa letsatsi tse tšesaane-filimi

(1) Boleng ba khanya ea letsatsi e nang le sekhahla se phahameng sa ho monya.

Li-GaAs ke tsa lisebelisoa tsa li-semiconductor tsa III-V, 'me lekhalo la eona la matla ke 1.4eV, e leng feela boleng ba mahlaseli a letsatsi a phahameng a ho monya, a loketseng haholoanyane ho lumellana le mahlaseli a letsatsi.

(2) Ho hanyetsa mocheso o phahameng.

Tlas'a boemo ba 250 ° C, ts'ebetso ea phetoho ea photoelectric e ntse e le ntle haholo, 'me katleho ea eona e phahameng ka ho fetisisa ea ho fetola photoelectric ke hoo e ka bang 30%, e leng e loketseng ka ho khetheha bakeng sa mocheso o phahameng o lebisang lifilimi tse tšesaane tsa mahlaseli a letsatsi.

(3) Theko e tlaase.

Ho sebelisa li-wafers tsa silicon e le li-substrates, mokhoa oa heteroepitaxial oa theknoloji ea MOCVD ke mokhoa o tšepisang oa ho fokotsa litšenyehelo tsa lisele tsa GaAs.

2. Mefokolo ea lisele tsa letsatsi tse tšesaane-filimi

(1) Bonolo bo bobebe.

Mokhoa oa ho hōla oa lisele tsa letsatsi tse tšesaane o etsa qeto ea hore lisele tsa letsatsi tse tšesaane li na le tšekamelo ea ho senyeha, kahoo ho hanyetsa metsi ha lisebelisoa tse nang le fluorine tse hlokahalang ho koahela lisele tsa letsatsi tse tšesaane li batla li le matla ka makhetlo a 9 ho feta lisele tsa silicon tsa crystalline.

(2) Fotoinduation attenuation.

The attenuation ea tšesaane-filimi lisele tsa letsatsi ke hoo e ka bang 30%.

(3) Ts'ebetso ea phetoho ea lisele tsa letsatsi tse tšesaane tsa filimi e tlase.

Ka lebaka la ts'ebetso e phahameng ea phetoho ea lisele tsa letsatsi tsa membrane, boholo ba tsona li hlaha feela ka lihlahisoa tse nyane tsa elektronike tse tenyetsehang.

(4) Cadmium telluride ka thepa ea tlhahiso ke ntho e chefo.

Cadmium ke ntho e chefo e ngata e bokellanang ka har'a ketane ea lijo joalo ka mercury, e leng khahlano le mohopolo oa ho boloka tikoloho, ho bolokeha le ho se chefo. Litsi tse ngata le lilaboratori li batla mekhoa e meng e baballang tikoloho, e sebetsang hantle haholo, 'me bahlahisi ba letsatsi ba ntse ba hlahloba mekhoa ea ho khutlisa le ho sebelisa lisebelisoa tse nang le cadmium hape ho rarolla mathata a tikoloho.
