Lipatlisiso tsa morao-rao mabapi le liphanele tsa Photovoltaic

Hona joale, bafuputsi ba ntse ba sebetsa libakeng tse tharo tse kholo tsa lipatlisiso tsa photovoltaics: silicon ea crystalline, perovskites le lisele tsa letsatsi tse tenyetsehang.Libaka tsena tse tharo lia tlatsana, 'me li na le monyetla oa ho etsa hore theknoloji ea photovoltaic e atlehe haholoanyane.

Silicon ea kristale ke sesebelisoa sa semiconducting se sebelisoang hangata ka har'a liphanele tsa letsatsi.Leha ho le joalo, katleho ea eona e ka tlase haholo ho moeli oa theory.Ka hona, bafuputsi ba se ba qalile ho tsepamisa maikutlo ho nts'etsopele ea li-PV tsa crystalline tse tsoetseng pele.Laboratori ea Naha ea Matla a Tsosolositsoeng Hajoale e shebane le ho nts'etsapele lisebelisoa tse kopaneng tsa III-V tse lebelletsoeng ho ba le maemo a sebetsang hantle a fihlang ho 30%.

Perovskites ke mofuta o mocha oa sele ea letsatsi e sa tsoa bontšoa hore e sebetsa hantle ebile e sebetsa hantle.Lisebelisoa tsena li boetse li bitsoa "photosynthetic complexes."Li 'nile tsa sebelisoa ho eketsa bokhoni ba lisele tsa letsatsi.Ho lebelletsoe hore li tla fetoha khoebo nakong ea lilemo tse 'maloa tse tlang.Ha li bapisoa le silicon, li-perovskites li batla li le theko e tlaase 'me li na le mekhoa e mengata e ka sebelisoang.

Li-Perovskites li ka kopanngoa le lisebelisoa tsa silicon ho etsa sele ea letsatsi e sebetsang hantle le e tšoarellang.Lisele tsa letsatsi tsa kristale tsa Perovskite li ka sebetsa hantle ka liperesente tse 20 ho feta silicon.Lisebelisoa tsa Perovskite le Si-PV le tsona li bonts'itse maemo a ts'ebetso ea rekoto ho fihla ho liperesente tse 28.Ho feta moo, bafuputsi ba thehile theknoloji ea mahlakore a mabeli e nolofalletsang lisele tsa letsatsi ho kotula matla mahlakoreng ka bobeli a phanele.Sena se molemo ka ho khetheha bakeng sa lits'ebetso tsa khoebo, kaha se boloka chelete ka litšenyehelo tsa ho kenya.

Ho phaella ho li-perovskites, bafuputsi ba boetse ba hlahloba lisebelisoa tse ka sebetsang e le li-carriers kapa li-absorber tse khanyang.Lisebelisoa tsena li ka boela tsa thusa ho etsa hore lisele tsa letsatsi li be le chelete e ngata.Li ka boela tsa thusa ho etsa liphanele tse ke keng tsa senyeha habonolo.

Bafuputsi hajoale ba ntse ba sebeletsa ho theha sele ea letsatsi ea Tandem Perovskite e sebetsang hantle haholo.Sele ena e lebelletsoe ho rekisoa lilemong tse 'maloa tse tlang.Bafuputsi ba sebelisana 'moho le Lefapha la Matla la US le National Science Foundation.

Ho feta moo, bafuputsi ba ntse ba sebetsa ka mekhoa e mecha ea ho kotula matla a letsatsi lefifing.Mekhoa ena e kenyelletsa distillation ea letsatsi, e sebelisang mocheso o tsoang phanele ho hloekisa metsi.Mekhoa ena e ntse e lekoa Univesithing ea Stanford.

Bafuputsi ba ntse ba etsa lipatlisiso mabapi le tšebeliso ea lisebelisoa tsa PV tsa thermoradiative.Lisebelisoa tsena li sebelisa mocheso o tsoang phanele ho fehla motlakase bosiu.Theknoloji ena e ka ba molemo haholo-holo maemong a leholimo a batang moo katleho ea liphanele e fokolang.Mocheso oa lisele o ka nyolohela ho feta 25degC marulelong a lefifi.Lisele li ka boela tsa pholile ka metsi, e leng se etsang hore li atlehe haholoanyane.

Bafuputsi bana le bona ba sa tsoa sibolla tšebeliso ea lisele tsa letsatsi tse tenyetsehang.Liphanele tsena li khona ho mamella ho qoelisoa ka metsing 'me li bobebe haholo.Ba boetse ba khona ho mamella ho hasoa ke koloi.Lipatlisiso tsa bona li tšehetsoa ke Lenaneo la Eni-MIT Alliance Solar Frontiers.Ba boetse ba khonne ho hlahisa mokhoa o mocha oa ho hlahloba lisele tsa PV.

Patlisiso ea morao-rao mabapi le liphanele tsa photovoltaic e tsepamisitse maikutlo ho nts'etsopele ea mahlale a sebetsang hantle, a theko e tlase, le a tšoarellang.Boiteko bona ba lipatlisiso bo etsoa ke lihlopha tse ngata tse fapaneng United States le lefatšeng ka bophara.Theknoloji e tšepisang ka ho fetisisa e kenyelletsa lisele tsa letsatsi tse tšesaane tsa moloko oa bobeli le lisele tsa letsatsi tse tenyetsehang.
