MIT tsim cov ntawv tshiab-nyias hnub ci Photovoltaic Cells

Lub koom haum Massachusetts thev naus laus zis (MIT) tsis ntev los no tau tsim ib qho tshiab 'daim ntawv-thin' hnub ci photovoltaic cell uas tuaj yeem siv rau ntau qhov chaw los tsim cov hnub ci sib xyaw ua ke thiab ntau yam. Cov hlwb siv nanomaterials nyob rau hauv daim ntawv ntawm printable e-ink mus tso cov txheej txheem ntawm cov khoom siv hluav taws xob mus rau ib tug npaj peelable substrate uas tsuas yog 3 microns tuab, thiab tshuaj ntsuam luam ntawv rau deposit electrodes mus rau lub qauv kom tiav lub hnub ci module.

Cov kws tshawb fawb tau tuaj yeem tev cov ntawv luam tawm txog 15 microns tuab los ntawm cov yas substrate los tsim cov khoom siv hnub ci ultra-hnav, tus neeg sau xov xwm tau kawm. Cov kws tshawb fawb tom qab ntawd tau ua raws li lawv cov khoom siv rau cov khoom siv hnyav ua lag luam hu ua Dyneema, uas hnyav li 13 grams ib square meter.

Cov hlwb tseem tsis tau nce mus txog qib kev tsim khoom lag luam thiab yuav tsum tau muab qhwv rau lwm cov khoom siv tiv thaiv kom tsis txhob muaj kev puas tsuaj thaum lawv raug rau ib puag ncig. MIT tau hais tias cov khoom siv carbon-based organic siv hauv cov txheej txheem tsim khoom tuaj yeem hloov pauv los ntawm kev sib cuam tshuam nrog cov dej noo thiab oxygen, uas tuaj yeem ua rau tsis zoo.

Txoj kev tshawb no hais tias cov modules tsim 730W / kg ntawm lub zog thaum muaj kev ywj pheej nyob rau hauv kev sim thiab nyob ib ncig ntawm 370W / kg thaum xa tawm ntawm Dyneema fabrics.

Ib tug ntawm cov kws tshawb fawb, Mayuran Saravanapavanantham, hais tias tam sim no pab neeg txhim kho tab tom sim nrog encapsulating lub hnub ci hlwb hauv iav tuab, uas yuav ntxiv qee qhov hnyav tab sis tuaj yeem pab tshawb nrhiav kev lag luam yav tom ntej.
