Kutsvaga kwekuramba kuchiwedzera kushanda zvakanaka mukushandurwa kwesimba rezuva kwakatungamira mukutsvagisa kupfuura echinyakare silicon-based pn junction solar maseru. Imwe inovimbisa nzira iri muSchottky diode solar maseru, inopa yakasarudzika nzira yekunyudza mwenje uye kugadzirwa kwemagetsi.
Kunzwisisa Zvinokosha
Masero ezuva echinyakare anotsamira pane pn junction, apo inopomerwa zvakanaka (p-type) uye yakashata (n-type) semiconductor inosangana. Mukupesana, Schottky diode solar masero anoshandisa simbi-semiconductor junction. Izvi zvinogadzira Schottky chipingamupinyi, chinoumbwa neakasiyana mazinga esimba pakati pesimbi uye semiconductor. Chiedza chinorova sero chinofadza maerekitironi, zvichiita kuti asvetuke chipingamupinyi ichi uye kuti aite simba remagetsi.
Zvakanakira zveSchottky Diode Solar Cells
Schottky diode solar masero anopa akati wandei mabhenefiti pane echinyakare pn junction maseru:
Mutengo-Unobudirira Kugadzira: Maseru eSchottky anowanzo kuve akareruka kugadzira kana achienzaniswa nepn junction maseru, izvo zvinogona kutungamira kudzikisa mitengo yekugadzira.
Enhanced Light Trapping: Iyo simbi yekubata muSchottky maseru inogona kunatsiridza mwenje kuteya mukati mesero, ichibvumira kunyudzwa kwechiedza.
Inokurumidza Kuchaja Yekufambisa: Iyo Schottky chipingamupinyi chinogona kufambisa nekukurumidza kufamba kwemafoto-anogadzirwa maerekitironi, zvichigona kuwedzera shanduko inoshanda.
Kuongorora kwezvinhu zveSchottky Solar Cells
Vatsvagiri varikushingairira kuongorora zvakasiyana siyana zvekushandisa muSchottky solar masero:
Cadmium Selenide (CdSe): Nepo masero eCdSe Schottky aripo achiratidza mashandiro ane mwero akatenderedza 0.72%, kufambira mberi kwehunyanzvi hwekugadzira senge electron-beam lithography inopa vimbiso yekuvandudza mune ramangwana.
Nickel Oxide (NiO): NiO inoshanda sechinhu chinovimbisa p-mhando zvinhu mumaseru eSchottky, ichiita mashandiro anosvika 5.2%. Yayo yakakura bandgap zvimiro inosimudzira kunyudzwa kwechiedza uye yakazara sero kuita.
Gallium Arsenide (GaAs): GaAs Schottky masero akaratidza kushanda kunopfuura 22%. Nekudaro, kuwana kuita uku kunoda yakanyatsogadzirwa simbi-insulator-semiconductor (MIS) chimiro chine inodzorwa oxide layer.
Matambudziko uye Nhungamiro Yeramangwana
Pasinei nekugona kwavo, Schottky diode solar masero anotarisana nemamwe matambudziko:
Recombination: Kubatanidzwazve kwemaelectron-hole pairi mukati mesero kunogona kudzikamisa kushanda zvakanaka. Imwe tsvakurudzo inodiwa kuderedza kurasikirwa kwakadaro.
Barrier Height Optimization: Iyo Schottky barriers urefu inokanganisa zvakanyanya kushanda zvakanaka. Kuwana chiyero chakakwana pakati pechipingamupinyi chepamusoro chekupatsanurwa kwakanaka kwechaji uye chivharo chakaderera chekurasikirwa kwesimba kushoma kwakakosha.
Mhedziso
Schottky diode solar masero anobata mukana wakakura wekushandura shanduko yesimba rezuva. Nzira dzavo dzekugadzira dzakareruka, kugona kunyudzwa kwemwenje, uye kukurumidza kuchaja nzira dzekufambisa dzinovaita tekinoroji inovimbisa. Sezvo tsvagiridzo ichidzika mukati mekugadzirisa zvinhu uye nzira dzekudzikisa zvakare, isu tinogona kutarisira kuona Schottky diode solar masero achibuda semutambi akakosha mune ramangwana rekuchenesa simba rekugadzira.
