This paper demonstrates the positive role of Co atoms on the performance of CdS-based hybrid photovoltaics. Spherical shaped CdS and CdS:Co films were grown on indium tin oxide (ITO)-covered glass slides, while P3HT was individually covered on these spheres. The transparency of devices improved with introducing the Co atoms into CdS matrix in the near infrared region, while a corresponding reduction in absorption was noted. Photoluminescence (PL) data showed that a diminish in the peak intensity of PL, suggesting the development of additional defect levels in the band gap which behaves as non-radiative recombination centers. The current density-voltage (J-V) characteristics indicated that the ITO/N719/CdS:Co(5%)/P3HT/Ag device achieved an overall efficiency of 0.028%, representing almost a sixfold increase over the control device. This enhancement is possibly attributed to the enhanced generation of electron-hole pairs owing to effective charge separation at the CdS:Co/P3HT interface.

Bu makale, CdS tabanlı hibrit güneş hücrelerinin performansında Co atomlarının olumlu rolünü ortaya koymaktadır. Küresel şekilli CdS ve CdS:Co filmler indiyum kalay oksit (ITO) kaplı cam plakalar üzerine büyütülmüş ve bu kürecikler üzerine P3HT’nin bireysel olarak kaplandığı görülmüştür. Cihazların geçirgenliği, CdS matrisine Co atomlarının ilave edilmesiyle yakın kızılötesi bölgede artış gösterirken, buna karşılık gelen bir absorpsiyon azalması gözlemlenmiştir. Fotolüminesans (PL) verileri, PL pik şiddetinde bir düşüş olduğunu ve bu durumun, bant aralığında radyatif olmayan rekombinasyon merkezleri olarak işlev gören ek kusur seviyelerinin oluşumuna işaret ettiğini göstermiştir. Akım yoğunluğu-gerilim (J-V) karakteristikleri, ITO/N719/CdS:Co(5%)/P3HT/Ag cihazının %0,028’lik bir toplam verimlilik elde ettiğini ve bu verimliliğin referans cihazına kıyasla yaklaşık altı kat artış sağladığını göstermiştir. Bu iyileşmenin, CdS:Co/P3HT ara yüzündeki etkin yük ayrımı sayesinde artan elektron-delik çiftlerinin oluşumuna atfedilmektedir.
