Bayyana Mai yuwuwar: Schottky Diode Solar Cells don Ingantacciyar Gaba

Neman haɓaka haɓakar haɓakawa a cikin canjin makamashin hasken rana ya haifar da bincike sama da sel na haɗin pn na tushen silicon na gargajiya. Hanya ɗaya mai ban sha'awa ta ta'allaka ne a cikin ƙwayoyin hasken rana na Schottky diode, yana ba da hanya ta musamman don ɗaukar haske da samar da wutar lantarki.

Fahimtar Tushen

Kwayoyin hasken rana na gargajiya sun dogara da mahadar pn, inda madaidaicin cajin (nau'in p-type) da mummunan cajin (n-type) semiconductor suka hadu. Sabanin haka, Kwayoyin hasken rana na Schottky diode suna amfani da haɗin ƙarfe-semiconductor junction. Wannan yana haifar da shingen Schottky, wanda aka kafa ta matakan makamashi daban-daban tsakanin karfe da semiconductor. Hasken tantanin halitta yana motsa electrons, yana ba su damar tsallake wannan shinge kuma su ba da gudummawa ga wutar lantarki.

Amfanin Schottky Diode Solar Cells

Kwayoyin hasken rana na Schottky diode suna ba da fa'idodi da yawa akan ƙwayoyin haɗin pn na gargajiya:

Ƙirƙirar Tasirin Kuɗi: Kwayoyin Schottky gabaɗaya sun fi sauƙi don ƙira idan aka kwatanta da ƙwayoyin pn junction, mai yuwuwar haifar da ƙarancin farashin samarwa.

Ingantattun Tarkon Haske: Ƙarfe a cikin sel Schottky na iya inganta tarkon haske a cikin tantanin halitta, yana ba da damar ɗaukar haske mai inganci.

Sufuri mai Saurin Cajin: Katangar Schottky na iya sauƙaƙe saurin motsi na electrons ɗin da aka samar da hoto, mai yuwuwar haɓaka ingantaccen juzu'i.

Bincika Kayan Kaya don Kwayoyin Rana na Schottky

Masu bincike suna binciko abubuwa daban-daban don amfani a cikin ƙwayoyin hasken rana na Schottky:

Cadmium Selenide (CdSe): Yayin da ƙwayoyin CdSe Schottky na yanzu suna ba da ingantacciyar inganci a kusa da 0.72%, ci gaba a cikin fasahohin ƙirƙira kamar lithography na lantarki suna ba da alƙawarin haɓakawa na gaba.

Nickel Oxide (NiO): NiO yana aiki azaman nau'in p-type abu mai ban sha'awa a cikin ƙwayoyin Schottky, yana samun ingantattun abubuwan har zuwa 5.2%. Faɗin bandgap ɗin sa yana haɓaka ɗaukar haske da aikin tantanin halitta gabaɗaya.

Gallium Arsenide (GaAs): GaAs Schottky Kwayoyin sun nuna inganci fiye da 22%. Koyaya, samun wannan aikin yana buƙatar ƙirar ƙarfe-insulator-semiconductor (MIS) a hankali tare da madaidaicin Layer oxide.

Kalubale da Hanyoyi na gaba

Duk da yuwuwar su, ƙwayoyin hasken rana na Schottky diode suna fuskantar wasu ƙalubale:

Sake haɗawa: Sake haɗa nau'i-nau'i-nau'i-nau'i na lantarki a cikin tantanin halitta na iya iyakance iya aiki. Ana buƙatar ƙarin bincike don rage irin wannan asarar.

Haɓaka Tsawon Barrier: Tsayin shingen Schottky yana tasiri sosai. Nemo madaidaicin ma'auni tsakanin babban shinge don ingantaccen cajin rabuwa da ƙaramin shinge don ƙarancin asarar makamashi yana da mahimmanci.

Kammalawa

Kwayoyin hasken rana na Schottky diode suna riƙe da babban yuwuwar juyin juya halin hasken rana. Hanyoyin ƙirƙira su mafi sauƙi, ingantattun damar ɗaukar haske, da hanyoyin jigilar caji cikin sauri sun sa su zama fasaha mai ban sha'awa. Yayin da bincike ke zurfafa zurfafa cikin inganta kayan abu da dabarun sake hadewa, muna iya tsammanin ganin Schottky diode sel na hasken rana sun fito a matsayin babban dan wasa a nan gaba na samar da makamashi mai tsabta.
