Zvakanakira uye kuipa kweakaonda-firimu masero ezuva

Masero ezuva akaonda-firimu anoshandiswa zvakanyanya mu photovoltaic yekurima greenhouses uye photovoltaic zvivakwa zvinoda kufambisa kwechiedza. Unoziva here kuti ndezvipi zvakanakira uye zvakaipira zvematete-firimu solar maseru? Makore mangani iyo solar panel yakatetepa-firimu inotora makore mangani?

Parizvino, aripo akaonda-firimu masero ezuva anonyanya kusanganisira: cadmium telluride yakaonda-firimu solar masero, copper indium gallium selenide nhete-firimu solar masero, uye amorphous silicon nhete-firimu solar masero.

1. Zvakanakira zvitete-firimu masero ezuva

(1) Kukosha kwechiedza chezuva chine mwero wakanyanya wekunyura.

MaGaAs ndeye III-V komputa semiconductor zvinhu, uye gap rayo resimba i1.4eV, inongori kukosha kweyepamusoro kunyura mwero wezuva, iyo inonyanya kukodzera kuenderana neyakajeka yezuva.

(2) Kunyanya kupisa kwekushisa.

Pasi pemamiriro e250 ° C, iyo photoelectric conversion performance ichiri yakanaka kwazvo, uye yakanyanya kunaka yekushandura photoelectric inenge 30%, iyo inonyanya kukodzera kutonhora kwepamusoro-soro kuisa firimu shoma rezuva masero.

(3) Mutengo wakaderera.

Kushandisa silicon wafers se substrates, iyo heteroepitaxial nzira yeMOCVD teknolojia inzira inovimbisa kuderedza mari yeGaAs masero.

2. Kuipa kwemaonda-firimu masero ezuva

(1) Kusviba nyore.

Iyo nzira yekukura yeatete-firimu masero ezuva anotarisisa kuti matete-firimu ezuva masero anowanzoita deliquescent, saka kupikisa kwemvura kwemidziyo ine fluorine inodiwa kuvhara matete-firimu ezuva maseru ane simba rakapetwa ka9 pane ayo ecrystalline silicon masero.

(2) Photoinduced attenuation.

Iyo attenuation yeakaonda-firimu solar masero anenge 30%.

(3) Iko kutendeuka kwekushanda kwemaonda-firimu masero ezuva akaderera.

Nekuda kweiyo yakanyanya kutendeuka kushanda zvakanaka kwe membrane solar masero, mazhinji acho anongoonekwa mune madiki uye anochinjika zvigadzirwa zvemagetsi.

(4) Cadmium telluride mune yekugadzira zvinhu chinhu chine muchetura.

Cadmium chinhu chine muchetura zvakanyanya chinoungana mucheni yechikafu senge mercury, izvo zvinopesana nepfungwa yekuve nehushamwari kwezvakatipoteredza, yakachengeteka uye isina chepfu. Masangano mazhinji nemarabhoritari ari kutsvaga hushamwari kwezvakatipoteredza, dzimwe nzira dzepamusoro-soro, uye vagadziri vezuva vari kutsvaga nzira dzekudzoreredza uye kudzoreredza zvinhu zvine cadmium kugadzirisa matambudziko ezvakatipoteredza.
