Engineering mabatire a sola a m'badwo wotsatira

Mabatire achiwiri, monga mabatire a lithiamu ion, amayenera kuyitanidwanso mphamvu yosungidwa ikagwiritsidwa ntchito.Pofuna kuchepetsa kudalira kwathu mafuta, asayansi akhala akufufuza njira zokhazikika zowonjezeretsa mabatire achiwiri.Posachedwapa, Amar Kumar (wophunzira omaliza maphunziro awo ku labu ya TN Narayanan ku TIFR Hyderabad) ndi anzake asonkhanitsa batire ya lithiamu ion yokhala ndi zinthu zowoneka bwino zomwe zimatha kuwonjezeredwa mwachindunji ndi mphamvu yadzuwa.

Kuyesera koyambirira kogwiritsa ntchito mphamvu ya dzuwa kuti muwonjezerenso mabatire kunagwiritsa ntchito ma cell a photovoltaic ndi mabatire ngati magulu osiyana.Mphamvu ya dzuwa imasinthidwa ndi ma cell a photovoltaic kukhala mphamvu yamagetsi yomwe imasungidwa ngati mphamvu yamankhwala mu mabatire.Mphamvu zomwe zimasungidwa m’mabatirewa amazigwiritsira ntchito kupatsa mphamvu zipangizo zamagetsi.Kutumiza kwamphamvu kumeneku kuchokera ku chigawo chimodzi kupita ku chimzake, mwachitsanzo, kuchokera ku selo la photovoltaic kupita ku batri, kumabweretsa kutaya mphamvu.Pofuna kupewa kutayika kwa mphamvu, panali kusintha koyang'ana kugwiritsa ntchito zida za photosensitive mkati mwa batire lokha.Pakhala kupita patsogolo kwakukulu pakuphatikiza zinthu zowoneka bwino mkati mwa batire zomwe zimapangitsa kuti pakhale mabatire olumikizana kwambiri ndi solar.

Ngakhale amapangidwa bwino, mabatire a solar omwe alipo adakali ndi zovuta zina.Zina mwa zovuta izi zomwe zimagwirizanitsidwa ndi mitundu yosiyanasiyana ya mabatire a dzuwa ndi monga: kuchepa kwa mphamvu yogwiritsira ntchito mphamvu ya dzuwa yokwanira, kugwiritsa ntchito ma electrolyte organic omwe angawononge chithunzithunzi cha organic mkati mwa batire, komanso kupanga zinthu zam'mbali zomwe zimalepheretsa batire kuti isagwire bwino ntchito. nthawi yayitali.

Mu kafukufukuyu, Amar Kumar adaganiza zofufuza zida zatsopano zowonera zomwe zitha kuphatikizanso lithiamu ndikupanga batire ya solar yomwe ingakhale yotsimikizira kutayikira ndikugwira ntchito bwino pamalo ozungulira.Mabatire a dzuwa omwe ali ndi maelekitirodi awiri nthawi zambiri amakhala ndi utoto wojambula zithunzi mu imodzi mwa ma elekitirodi osakanikirana ndi gawo lokhazikika lomwe limathandiza kuyendetsa ma elekitironi kudzera mu batire.Elekitirodi yomwe ili yosakanikirana ndi zinthu ziwiri ili ndi malire pakugwiritsa ntchito bwino malo a electrode.Pofuna kupewa izi, ofufuza a gulu la TN Narayanan adapanga mawonekedwe a photosensitive MoS2 (molybdenum disulphide) ndi MoOx (molybdenum oxide) kuti azigwira ntchito ngati electrode imodzi.Pokhala heterostructure momwe MoS2 ndi MoOx zaphatikizidwa pamodzi ndi njira yoyika mpweya wamankhwala, ma elekitirodi amalola malo ochulukirapo kuti atenge mphamvu ya dzuwa.Pamene kuwala kwamagetsi kugunda pa electrode, MoS2 yojambula zithunzi imapanga ma elekitironi ndipo nthawi imodzi imapanga malo otchedwa mabowo.MoOx imasunga ma electron ndi mabowo padera, ndikusamutsa ma elekitironi ku dera la batri.

Batire ya solar iyi, yomwe idasonkhanitsidwa kotheratu, idapezeka kuti imagwira ntchito bwino ikakumana ndi kuwala kwadzuwa koyerekeza.Kapangidwe ka heterostructure elekitirodi yomwe imagwiritsidwa ntchito mu batire iyi yawerengedwa mozama ndi ma microscope ma electron.Olemba kafukufukuyu akuyesetsa kuti apeze njira yomwe MoS2 ndi MoOx zimagwirira ntchito limodzi ndi lithiamu anode zomwe zimapangitsa kuti pakhale masiku ano.Ngakhale batire ya solar iyi imakwaniritsa kulumikizana kwapamwamba kwa zinthu zowoneka bwino ndi kuwala, ikadakwanitse kukwaniritsa milingo yabwino kwambiri yapano kuti iwonjezere batire ya lithiamu ion.Poganizira izi, labu ya TN Narayanan ikuwunika momwe ma elekitirodi opangidwa ndi heterostructure angapangire njira yothana ndi zovuta zamabatire amasiku ano adzuwa.
