Unugyada cadceedda ee dheeha (DSSCs) ayaa soo jiitay fiiro badan sannadihii la soo dhaafay sababtoo ah samaynta qiime jaban marka loo eego unugyada cadceedda ku salaysan ee silikoon iyo dhuuban.In kastoo, platinum uu yahay shay aad u wanaagsan oo loo isticmaalo diyaarinta korantada korantada (CEs) ee DSSC-yada waa qaali.Beddelka beddelka platinum (Pt) ee la baadhay waa maaddooyinka kaarboonka, polymers-ka iyo isku-dhafka.Shaqadan, counter-electrode-ka DSSC-yada waxaa lagu sameeyay iyadoo la isticmaalayo walxo kaarboon ah oo laga helay garaafaynta sukrose heerkul sare ah.Kaarboonka kaarboonka laga soo saaray garaafaynta sukrose waxaa lagu sameeyay polyvinylpyrrolidone (PVP) sidii surfactant iyo dahaar uu helay takhtarka oo ku dul saaray slurry substrate-ka galaaska FTO.Cufnaanta hadda (Jsc) iyo korantada wareegga furan (V(OC)) ee unugga la sameeyay (aagga 0.25 cm(2)) waxay ahayd 10.28 mAc m (-2) iyo 0.76 V siday u kala horreeyaan.Hufnaanta unuggu waxa ay ahayd 4.33% taas oo waxyar ka yara hoosaysay ta loo helay unugyo la mid ah iyadoo la isticmaalayo korantada platinum-ku salaysan.
