Özet:

 Electron transfer layer ETL is vital importance for obtaining high performance perovskite solar cells PSC. This can be achieved by producing tin oxide SnO2 ETL, which is produced at high temperature, has appropriate energy band alignment, high optical transmittance and high carrier mobility. ETL produced at low temperature generally has low crystallization, poor electron mobility, and abundant defects at grain boundaries. This prevents efficient load transport, creates recombination and causes serious energy losses. In this paper, 1-ethyl-3-methylimidazolium tetrafluoroborate EMIMBF4 ionic liquid IL was added into SnO2 ETL in different concentrations to improve these negative properties caused by the production of SnO2 ETL at low temperature, using spin-coater technique at low temperature 100 C was prepared. Optical properties of EMIMBF4 IL doped SnO2 ETL and perovskite films were investigated using UV-vis-NIR spectrometry and photoluminescence spectrophotometer PL measurement. The surface morphology of the produced films was investigated by field emission scanning electron microscopy FE-SEM and atomic force microscopy AFM. The crystal structure analysis of the films was carried out by X-ray diffraction XRD. The hydrophilichydrophobic behavior of the surfaces was evaluated using contact angle measurement. It has been observed that EMIMBF4 doped SnO2 ETL films have fewer surface defects by passivation of surface defects compared to pure SnO2 ETL film and they crystallize at a relatively low and economical temperature 100C. It has been determined that 0.5 EMIMBF4 doped films give better optical and structural results than other doped and pure ETL films, albeit low.

 Yüksek performansa sahip perovskite güneş hücreleri PSCnin elde edilebilmesi için elektron transfer tabakası ETL oldukça hayati öneme sahiptir. Bu durum yüksek sıcaklıkta üretilen, uygun enerji bandı hizalamasına ve yüksek optik geçirgenlik ile yüksek taşıyıcı hareketliliğine sahip kalay oksit SnO2 ETLnın üretilebilmesiyle mümkün olabilmektedir. Düşük sıcaklıkta üretilen ETLnda genellikle düşük kristalleşme, zayıf elektron hareketliliği ve tane sınırlarında bol miktarda kusur meydana gelmektedir. Bu da verimli yük taşınmasını engelleyerek, rekombinasyon oluşturmakta ve ciddi enerji kayıplarına sebep olmaktadır. Bu çalışmada düşük sıcaklıkta SnO2 ETL üretiminden kaynaklanan bu olumsuz özellikleri iyileştirmek amacıyla SnO2 ETL içerisine 1-etil-3-metilimidazolyum tetrafloroborat EMIMBF4 iyonik sıvı ILsı farklı konsantrasyonlarda katkılanarak döndürerek kaplama spin-coater tekniği ile düşük sıcaklıkta 100 C hazırlanmıştır. EMIMBF4 IL katkılı SnO2 ETL ve perovskite filmlerin optik özellikleri UV-vis-NIR spektrometresi ve fotolüminesans spektrofotometresi PL ölçümü kullanılarak araştırılmıştır. Üretilen filmlerin alan emisyonlu taramalı elektron mikroskobu FE-SEM ve atomik kuvvet mikroskobu AFM ile yüzey morfolojisi incelenmiştir. Filmlerin kristal yapı analizi ise X-ışını kırınımı XRD ile gerçekleştirilmiştir. Temas açısı ölçümü kullanılarak yüzeylerin hidrofilikhidrofobik davranışları değerlendirilmiştir. EMIMBF4 katkılı SnO2 ETL filmlerin saf SnO2 ETL filme göre yüzey kusurlarının pasivize edilerek daha az yüzey kusurlarına sahip oldukları ve nispeten daha düşük ve ekonomik bir sıcaklık da 100C kristalleştikleri görülmüştür. 0.5 EMIMBF4 katkılı filmlerin düşük de olsa diğer katkılı ve saf ETL filmlere göre daha iyi optik ve yapısal sonuçlar verdiği tespit edilmiştir.
