Uma ngikutshele ukuthi ungakwazi sikhiqize amandla elanga ngemvula Ungahlala kanjani
Sesivele sazi ukuthi ukukhiqizwa kwemvula namandla elanga akuhambelani kahle futhi lokhu kwenzeka ngoba amaseli we-photovoltaic anciphisa kakhulu ukusebenza kwawo Mayelana nokukhiqizwa kukagesi, kukhulunywa ngakho ngezinsuku zemvula.
Ukushintsha lokhu futhi ukwenze kube mnandi ngokwengeziwe, uQunwei Tang, umholi weqembu le ososayensi baseChina, ufunda ukuthi kanjani ukuthuthukisa iseli elanga lokho kuyakwazi khiqiza amandla ngosizo lwe amaconsi emvula.
Uma bephumelela, amandla elanga ngokungangabazeki azosusa umthwalo omkhulu emahlombe akhe ngokungalungi kwalokho ngeke kube nenzuzo ngezinsuku ezinamafu nemvula.
Ngaleli zinga amandla elanga azobe engenakulinganiswa ukuqhudelana namanye amandla avuselelekayo, yize kungashiwo ukuthi lapho ilanga libalele kungakhiqizwa inani eliningi lamandla futhi ngezinsuku ezinamafu okungenani uhhafu noma ngaphansi kwalelo nani njengoba sibonile ku-athikili "Amandla elanga aqhathaniswa neminye imithombo yamandla."
Ya ngokwakhiwa kwaleli seli elisha elanga sizokwazi ukuqhubeka nokukhiqiza ngamaconsi emvula, uqweqwe lukhekhe lamandla elanga.
IGraphene
Leli qembu lososayensi eliholwa yiQunwei Tang, okukhulunywe ngalo ngenhla, ngicabange ukusebenzisa i-graphene ekwakhiweni kweseli elanga.
IGraphene uma kwenzeka ungazi kuyinto eyakhiwe ngekhabhoni emsulwa, ama-athomu alo akhiwe ngephethini ejwayelekile efana ne-graphite.
Ishidi le-athomu elilodwa le-graphene cishe Iqine ngokuphindwe ka-200 kunensimbi uqobo lwayo futhi ukuminyana kwayo kuyafana ne-carbon fiber futhi kunjalo ilula kune-aluminium (cishe izikhathi ezingu-5 ukukhanya). Kubuye kube yi- umqhubi omuhle kagesi.
Ngazo zonke lezi zici, ngubani ongeke amnake?
Iseli elanga
Yebo, iseli elisha elanga lifaka ungqimba lwe-graphene ubukhulu be-athomu futhi iyakwazi ukukhiqiza amandla elanga emaconsi emvula uqobo.
Uma ucabanga lokho amazwe amaningi athathwa njengemvula enkulu njengezinye izingxenye zeChina, iNew Zealand, iHawaii, njll. kanye nokusebenza kwamapaneli elanga kwehla kakhulu ngenxa yalesi simo sezulu, ngokusho ukuthi banamaphaneli elanga afakiwe, Ukuthuthuka kwaleli seli lelanga kungukuthuthuka kwamandla elanga.
Ukusebenza
Lolu ungqimba oluncane lwe-graphene lwanele ukufeza imiphumela emihle.
Ukuba ngumqhubi omuhle kagesi njengoba ngishilo phambilini ngezimpawu zegraphene inani elikhulu lama-electron liyakwazi ukuhamba ebusweni begobolondo.
Lapho lina Ukusabela kwe-Lewis acid-base ngaleyo ndlela ivumela i- ukukhiqizwa kwamandla.
Ukuphendula kwe-Lewis acid-base noma ukusabela kwe-neutralization kumane nje kungukusabela kwamakhemikhali okwenzeka phakathi kwe-asidi nesisekelo esikhiqiza usawoti namanzi.
Igama elithi "usawoti" lichaza noma iyiphi into e-ionic okuvela kuyo isisekelo sayo (Na+ I-NaOH) futhi i-anion yayo ivela ku-asidi (Cl- I-HCl).
Ukusabela kokungathathi hlangothi kuvame ukubabazeka, okusho ukuthi banikela ngamandla ngendlela yokushisa. Nanku umklomelo!
Imvamisa zibizwa ngokuthi yi-neutralization ngoba lapho i-asidi iphendula ngesisekelo, ziyanciphisa izakhiwo zomunye nomunye.
Iziphumo
Leli seli elanga usesigabeni sokuklama nokuhlola okusho ukuthi sisekhona isikhathi eside ukuyibona emakethe (akukho ngisho intengo yize lobu buchwepheshe obusha kusaxoxwa ngabo)
Kuningi okusamele kwenziwe nokuthuthuka kusukela lapho ihlose ukuthuthukisa ukusebenza kahle kwakho.
Okwamanje isivuno saso sizungeze u-6.5%, inani eliphansi kakhulu uma sibona iningi le- ama-solar panel manje abane- Isivuno esingu-22% (kimina futhi ngikude kakhulu nokukwazi ukusebenzisa amandla elanga kahle).
