Phuputso ea morao-rao mabapi le liphanele tsa photovoltaic

Hona jwale, bafuputsi ba ntse ba sebetsa dikarolong tse tharo tse ka sehloohong tsa dipatlisiso tsa photovoltaics: kristale ya silicon, perovskites le disele tsa letsatsi tse tenyetsehang. Dibaka tsena tse tharo di a tlatsana, mme di na le bokgoni ba ho etsa hore theknoloji ya photovoltaic e sebetse hantle le ho feta.

Silicone ea kristale ke thepa e sebelisoang haholo ea semiconducting liphanele tsa letsatsi. Leha ho le joalo, katleho ea eona e ka tlase haholo ho moeli oa khopolo-taba. Ka hona, bafuputsi ba qalile ho tsepamisa maikutlo ho nts'etsapele li-PV tsa kristale tse tsoetseng pele. Laboratori ea Naha ea Matla a Nchafalitsoeng hajoale e shebane le ho nts'etsapele thepa ea likhokahano tse ngata tsa III-V tse lebelletsoeng ho ba le maemo a katleho a fihlang ho 30%.

Li-Perovskite ke mofuta o mocha oa sele ea letsatsi o sa tsoa bontšoa hore o sebetsa hantle ebile o sebetsa hantle. Lisebelisoa tsena li boetse li bitsoa "li-complexes tsa photosynthetic." Li 'nile tsa sebelisoa ho eketsa bokhoni ba lisele tsa letsatsi. Ho lebeletsoe hore li tla rekisoa lilemong tse 'maloa tse tlang. Ha li bapisoa le silicon, li-perovskite li theko e tlase haholo 'me li na le mefuta e mengata ea lits'ebetso.

Li-Perovskite li ka kopanngoa le thepa ea silicon ho etsa sele ea letsatsi e sebetsang hantle le e tšoarellang. Lisele tsa letsatsi tsa kristale tsa Perovskite li ka ba le katleho e kholo ho feta silicon ka liphesente tse 20. Lisebelisoa tsa Perovskite le Si-PV le tsona li bontšitse maemo a rekoto a katleho a fihlang ho liphesente tse 28. Ho phaella moo, bafuputsi ba thehile theknoloji ea bifacial e nolofalletsang lisele tsa letsatsi ho bokella matla mahlakoreng ka bobeli a phanele. Sena se molemo haholo bakeng sa lits'ebetso tsa khoebo, kaha se boloka chelete litšenyehelong tsa ho kenya.

Ntle le li-perovskite, bafuputsi ba boetse ba hlahloba thepa e ka sebetsang e le lijari tsa tjhaja kapa li-absorber tsa leseli. Lisebelisoa tsena li ka boela tsa thusa ho etsa hore lisele tsa letsatsi li be theko e tlaase. Li ka boela tsa thusa ho theha liphanele tse sa senyeheng habonolo.

Bafuputsi ba ntse ba sebetsa ho theheng sele ya letsatsi ya Tandem Perovskite e sebetsang hantle haholo. Sele ena e lebelletswe ho rekiswa dilemong tse mmalwa tse tlang. Bafuputsi ba sebelisana mmoho le Lefapha la Matla la US le Mokgatlo wa Naha wa Saense.

Ho phaella moo, bafuputsi ba ntse ba sebetsa le mekhoeng e mecha ea ho bokella matla a letsatsi lefifing. Mekhoa ena e kenyelletsa ho qhala ha matla a letsatsi, e sebelisang mocheso o tsoang phanele ho hloekisa metsi. Mekhoa ena e ntse e lekoa Univesithing ea Stanford.

Bafuputsi ba boetse ba batlisisa tšebeliso ea lisebelisoa tsa thermoradiative PV. Lisebelisoa tsena li sebelisa mocheso o tsoang phanele ho hlahisa motlakase bosiu. Theknoloji ena e ka ba molemo haholo maemong a leholimo a batang moo katleho ea phanele e lekanyelitsoeng. Mocheso oa lisele o ka eketseha ho feta 25degC marulelong a lefifi. Lisele li ka boela tsa pholisoa ke metsi, e leng se etsang hore li sebetse hantle haholoanyane.

Bafuputsi bana ba sa tsoa sibolla tšebeliso ea lisele tsa letsatsi tse tenyetsehang. Liphanele tsena li ka mamella ho qoelisoa ka metsing 'me li bobebe haholo. Li boetse li khona ho mamella ho haptjoa ke koloi. Lipatlisiso tsa bona li tšehetsoa ke Lenaneo la Meeli ea Letsatsi la Eni-MIT Alliance. Ba boetse ba khonne ho nts'etsapele mokhoa o mocha oa ho leka lisele tsa PV.

Phuputso ea morao-rao mabapi le liphanele tsa photovoltaic e shebane le ho nts'etsapele mahlale a sebetsang hantle, a theko e tlase, le a tšoarellang haholoanyane. Maiteko ana a lipatlisiso a etsoa ke lihlopha tse fapaneng United States le lefats'eng ka bophara. Mahlale a tšepisang ka ho fetisisa a kenyelletsa lisele tsa letsatsi tsa moloko oa bobeli tse tšesaane le lisele tsa letsatsi tse tenyetsehang.
