Nyanzvi dzefizikisi paYunivhesiti yeITMO dzakawana nzira itsva yekushandisa zvinhu zvinoonekera mumasero ezuvauku vachiramba vachishanda zvakanaka. Tekinoroji itsva iyi yakavakirwa pakushandisa mishonga inodhaka, iyo inochinja hunhu hwezvinhu nekuwedzera tsvina asi pasina kushandisa michina inodhura.

Mhedzisiro yekutsvagisa uku yakaburitswa muACSAPlied Materials & Interfaces (“Ion-gated small molecule OPVs: Interfacial doping of charge collectors and transport layers”).

Chimwe chezvinhu zvinonyanya kuomera musimba rezuva kugadzira zvinhu zvinopenya zvinonzwa chiedza. Firimu iri rinogona kuiswa pamusoro pemahwindo akajairwa kuti rigadzire simba pasina kukanganisa chitarisiko chechivako. Asi kugadzira masero ezuva anobatanidza kushanda zvakanaka nekufambisa chiedza zvakanaka kwakaoma zvikuru.

Masero ezuva akapfava ane firimu diki ane simbi isingaonekwe kumashure inobata chiedza chakawanda. Masero ezuva anopenya anoshandisa maelectrode ekumashure anotumira chiedza. Muchiitiko ichi, mamwe maphoton anorasika paanenge achipfuura, zvichikanganisa mashandiro emuchina wacho. Uyezve, kugadzira electrode yekumashure ine hunhu hwakakodzera kunogona kudhura zvikuru,” anodaro Pavel Voroshilov, muongorori paITMO University's School of Physics and Engineering.

Dambudziko rekusashanda zvakanaka rinogadziriswa nekushandisa doping. Asi kuve nechokwadi chekuti tsvina yashandiswa nemazvo pachinhu ichi kunoda nzira dzakaoma uye michina inodhura. Vaongorori veITMO University vakakurudzira tekinoroji yakachipa yekugadzira "ma solar panels" asingaoneki - iyo inoshandisa ionic liquids kugadzira chinhu ichi, iyo inoshandura hunhu hwezvikamu zvakagadziriswa.

"Pakuedza kwedu, takatora solar cell diki ine mamorekuru ndokubatanidza nanotubes pairi. Tevere, takaisa nanotubes tichishandisa ion gate. Takagadzirisawo transport layer, iyo ine basa rekuita kuti charge kubva ku active layer isvike zvakanaka pa electrode. Takakwanisa kuita izvi tisina vacuum chamber uye tichishanda mumamiriro ekunze. Chataifanira kuita chete kudonhedza imwe ionic liquid toisa voltage shoma kuti tigadzire mashandiro anodiwa." akawedzera Pavel Voroshilov.

Pakuyedza tekinoroji yavo, masayendisiti akakwanisa kuwedzera kushanda kwemabhatiri zvakanyanya. Vaongorori vanotenda kuti tekinoroji imwecheteyo inogona kushandiswa kuvandudza mashandiro emamwe marudzi emasero ezuva. Iye zvino vari kuronga kuyedza zvinhu zvakasiyana uye kuvandudza tekinoroji yekushandisa zvinodhaka.
