Effect of Efficiencies of Adding Silver Nanoparticles' to PEDOT:PSS in The Polymer Solar Cell

Öz

In this study, silver (Ag) nanoparticles of different sizes (5 nm, 10 nm, 20 nm and 30 nm) were doped on Poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS), which is used as a hole conducting layer in polymer solar cells, and coated on Indium tin oxide (ITO) by Spin Coating method. PEDOT:PSS samples with and without additives were annealed at 110 °C, 130 °C and 150 °C. Poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl C61 butyric acid methyl ester (PCBM) mixture were coated on PEDOT:PSS to produce polymer solar cells with ITO/PEDOT:PSS/P3HT:PCBM/Al structure and It was annealed at 110°C for 20 minutes. Currentvoltage (I-V) measurements of the produced samples were taken and their graphics were drawn. According to the data obtained from the calculations, it was determined that the highest photovoltaic efficiency of 2.59% was obtained by annealing at 130°C for the 5 nm Ag doped sample.

Polimer Güneş Hücrelerinde PEDOT:PSS’ye Gümüş Nanoparçacık Katkılamanın Verime Etkisi

Öz

Bu çalışmada, polimer güneş hücrelerinde boşluk ileten katman olarak kullanılan Poly(3,4- ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS)’ye değişik boyutlardaki (5 nm, 10 nm, 20 nm ve 30 nm) gümüş (Ag) nanoparçacıkları katkılanarak ITO (Indium tin (kalay) oxide) üzerine Döndürerek Kaplama (Spin Coating) yöntemiyle kaplandı. Katkılı ve katkısız PEDOT:PSS numuneleri, 110 °C, 130 °C ve 150 °C sıcaklıklarında tavlandı. Daha sonra Poly(3-hexylthiophene) (P3HT) ve [6,6]-phenyl C61 butyric acid methyl ester (PCBM) karışımı PEDOT:PSS üzerine kaplanarak ITO/PEDOT:PSS/P3HT:PCBM/Al yapıdaki polimer güneş hücreleri üretildi ve 110°C sıcaklıkta 20 dakika süreyle tavlandı. Üretilen numunelerin akım-voltaj (I-V) ölçümleri alınarak grafikleri çizildi. Yapılan hesaplamalardan elde edilen verilere göre en yüksek fotovoltaik verim %2.59 ile 5 nm Ag katkılı numunenin 130°C’deki tavlama ile elde edildiği tespit edildi.
