Spin Kaplama Yöntemiyle Hazırlanan Organik Arayüzeyi İçeren Al/p‐Si Diyotunun Fotovoltaik Parametreleri Üzerine Aydınlanmanın Etkisi

Bu çalışmada, organik ara yüzey olarak brom timol mavisi (BTB) kullanılarak foto voltaik aygıt uygulaması rapor edilmiştir. Kimyasal olarak temizlenen tabanın mat yüzeyine ısıl buharlaştırma yöntemiyle Al arka kontak oluşturulduktan sonra, dönel kaplama yardımıyla organik ara yüzey tabakası Si taban üzerine kaplanmıştır. Aygıt üretimini tamamlamak için, bu organik ince filmin üzerine Al üst kontaklar oluşturulmuştur. Aygıtın foto voltaik özelliklerini iyileştirmek amacıyla hazırlanan örnek farklı şiddetlerdeki aydınlamaya maruz bırakılmıştır. Farklı aydınlanmalar altında aygıtın açık devre voltajı (Voc), kısa devre akımı (Isc) ve çıkış gücü (P) gibi temel güneş pili parametreleri belirlenmiştir. Aydınlanma şiddetinin artması ile fotoakım ve fotogerilim değerleri artmıştır. Ayrıca, yüksek ve düşük frekans değerlerinde aygıt sığasının voltaj bağımlılığı rapor edilmiştir. Aydınlanma şiddetinin üretilen aygıtın fotovoltaik parametreleri üzerinde önemli bir etkisinin olduğu sonucuna varılmıştır.

Effect of Illumination on the Photovoltaic Parameters of Al/p‐Si Diode with an Organic Interlayer Prepared by Spin Coating Method

In this study, the photovoltaic device application of bromothymol blue (BTB) as an organic interlayer has been reported. After Al back contact fabrication on the surface of the chemically cleaned substrate by thermal evaporation method, the organic interlayer has been grown on p‐Si substrate via spin coating technique. Al top contacts have been formed on this organic thin film to finalize the device constructions. The different illumination intensities were exposed to the prepared sample for the enhancement in the photovoltaic properties of device. The fundamental photovoltaic parameters such as open circuit voltage (Voc), short circuit current (Isc) and output power (P) were determined for the device under different illuminations. The photocurrent and the photo voltage have been increased with the increasing in illumination intensity. The dependence of the capacitance on the voltage at high and low frequency has been also reported for the studied device. Consequently, it has been confirmed that the illumination intensity has an important influence on the photovoltaic parameters of the device.
