Abstract

Bu çalışmanın amacı, geniş spektrumlu aydınlatma altında iki yüzeyli silikon güneş pilinin
difüzyon kapasitansı ve aşırı azınlık taşıyıcı yoğunluğu teorik çalışmasının sunulmasıdır. Güneş pili aşırı
azınlık taşıyıcısından fotoakım ve fotogerilim yoğunluğu türetilmiştir. Difüzyon kapasitansı hem voltajın
fonksiyonu ile hem de bağlantı yüzeyi rekombinasyon hızı ile ölçülmüştür. Elektrik polarizasyon etkileri
farklı C-V (Difüzyon kapasitansı- Gerilim) grafkleri ile gösterilmiştir. Tüm çalışılan parametreler
için, karakterizasyon voltaj kapasitansının elektrik alan parametreleri üzerindeki etkisi ve kavşak
rekombinasyon hızı boyunca hücrenin operasyon noktasının etkisi gösterilmiştir

Capacitance Voltage Characterization of Bifacial Silicon Solar Cell Under Polychromatic Modulated Illumination

Abstract

The aim of this work is to present a theorical study of a capacitance voltage characterization
of a bifacial silicon solar cell under polychromatic modulated illumination. From the excess minority
carrier’s density in the solar cell, the photocurrent density and the photovoltage are derived. The diffusion
capacitance was measured with both as a function of voltage and the junction surface recombination
velocity. Electric polarization effects are shown through different C-V plots. For all the studied parameters,
we exhibited the effect of electric feld parameters on the capacitance voltage characterization and the
operating point of the cell through the junction recombination velocity.  

Keywords
