Kuwulula Zomwe Zingatheke: Maselo a Solar a Schottky Diode a Tsogolo Lowala

Kufunitsitsa kochulukirachulukira pakusinthika kwa mphamvu ya dzuwa kwadzetsa kufufuza kupitilira ma cell achikhalidwe a silicon-based pn junction solar. Njira imodzi yodalirika ili m'maselo a dzuwa a Schottky diode, omwe amapereka njira yapadera yoyamwitsa komanso kupanga magetsi.

Kumvetsetsa Zofunika Kwambiri

Maselo amtundu wa dzuwa amadalira pn mphambano, pomwe ma semiconductor abwino (p-type) ndi olakwika (n-type) amakumana. Mosiyana ndi izi, ma cell a solar a Schottky diode amagwiritsa ntchito polumikizira zitsulo-semiconductor. Izi zimapanga chotchinga cha Schottky, chopangidwa ndi magawo osiyanasiyana amphamvu pakati pa chitsulo ndi semiconductor. Kuwala komwe kumakhudza selo kumasangalatsa ma elekitironi, kuwalola kulumpha chotchinga ichi ndikuthandizira kuti magetsi aziyenda.

Ubwino wa Schottky Diode Solar Cells

Maselo a dzuwa a Schottky diode amapereka maubwino angapo kuposa ma cell a pn junction:

Kupanga Kopanda Mtengo: Maselo a Schottky nthawi zambiri amakhala osavuta kupanga poyerekeza ndi ma pn junction cell, zomwe zingapangitse kuti mtengo wopangira ukhale wotsika.

Kukwezera Kuwala Kwambiri: Kulumikizana kwachitsulo m'maselo a Schottky kumatha kupititsa patsogolo kutsekeka kwa kuwala mkati mwa selo, kulola kuyamwa bwino kwa kuwala.

Mayendedwe Othamanga Kwambiri: Chotchinga cha Schottky chimatha kuthandizira kuyenda mwachangu kwa ma elekitironi opangidwa ndi zithunzi, zomwe zitha kuwonjezera kusinthika kwachangu.

Kufufuza Kwazinthu Zokhudza Ma cell a Solar a Schottky

Ofufuza akufufuza mwachangu zida zosiyanasiyana zogwiritsidwa ntchito m'maselo a dzuwa a Schottky:

Cadmium Selenide (CdSe): Ngakhale maselo amakono a CdSe Schottky amawonetsa mphamvu pang'onopang'ono pafupifupi 0.72%, kupita patsogolo kwa njira zopangira zinthu monga electron-beam lithography kumapereka lonjezo la kusintha kwamtsogolo.

Nickel Oxide (NiO): NiO imagwira ntchito ngati p-type yodalirika m'maselo a Schottky, kukwaniritsa mphamvu mpaka 5.2%. Mawonekedwe ake a bandgap ambiri amathandizira kuyamwa kwa kuwala komanso magwiridwe antchito a cell.

Gallium Arsenide (GaAs): Maselo a GaAs Schottky asonyeza mphamvu zoposa 22%. Komabe, kuti mukwaniritse ntchitoyi pamafunika chitsulo-insulator-semiconductor (MIS) chopangidwa mwaluso chokhala ndi wosanjikiza woyendetsedwa bwino wa oxide.

Mavuto ndi Njira Zamtsogolo

Ngakhale ali ndi mphamvu, maselo a dzuwa a Schottky diode amakumana ndi zovuta zina:

Kuphatikizikanso: Kuphatikizikanso kwa ma electron-hole awiriawiri mkati mwa selo kumatha kuchepetsa magwiridwe antchito. Kafukufuku wowonjezereka akufunika kuti achepetse kutayika koteroko.

Kukhathamiritsa kwa Barrier Height: Kutalika kwa chotchinga cha Schottky kumakhudza kwambiri magwiridwe antchito. Kupeza bwino mulingo woyenera pakati chotchinga mkulu kwa imayenera mlandu kulekana ndi otsika chotchinga kuti mphamvu zochepa kutaya mphamvu n'kofunika.

Mapeto

Maselo a dzuwa a Schottky diode ali ndi kuthekera kwakukulu kosinthira kutembenuka kwa mphamvu ya dzuwa. Njira zawo zosavuta zopangira, kukulitsa luso la kuyamwa kwa kuwala, komanso njira zoyendetsera zolipirira mwachangu zimawapangitsa kukhala ukadaulo wodalirika. Pamene kafukufuku akuwunikira mozama za kukhathamiritsa kwa zinthu ndi njira zochepetseranso, titha kuyembekezera kuwona ma cell a solar a Schottky diode akuwoneka ngati gawo lofunikira kwambiri m'tsogolomu kupanga mphamvu zoyera.
