Abstract
În cadrul acestui studiu au fost cercetate proprietăţile fizice ale straturilor subţiri de ftalocianină de cupru (CuPc) depuse în vid prin metoda volumului cvasiînchis, dar şi a dispozitivelor fotovoltaice pe baza acestora. A fost studiată influenţa tratării termice asupra structurii şi proprietăţilor optice ale straturilor CuPc utilizând metoda difracţiei de raze X şi spectroscopia optică (transmitanţa, reflectanţa). Au fost fabricate structurile ITO/CuPc/Al şi ITO/PEDOT:PSS/CuPc/Al şi studiate proprietăţile fotoelectrice ale acestora. S-a constatat ca utilizarea stratului de PEDOT:PSS îmbunătăţeşte parametrii fotovoltaici, în special tensiunea de circuit deschis.
In this study, properties of copper phthalocianine (CuPc) films deposited by close space sublimation and photovoltaic devices based on them were investigated. The effect of the thermal threatment in different conditions on the structure and the optical properties were investigated by XRD analys is and optical spectroscopy (transmittance and reflectance). The ITO/CuPc/Al si ITO/PEDOT:PSS/CuPc/Al structures were fabricated and the photoelectric properties were studied. Was established that the utilization of the PEDOT:PSS layer in the fabrication of the structure improve photovoltaic parameters, especially open circuit voltage.
