In
this study, the effect on the efficiency of CdS/CdTe solar cell with MoO3 buffer
layer was examined. Two sample was grown as Cam/FTO/SnO2/CdS/CdTe/Au
and Cam/FTO/SnO2/CdS/CdTe/MoO3/Au. MoO3 layer
was deposited as a buffer layer between CdTe and metal electrode in the back
contact of CdTe solar cell. Solar cells were grown on glass/fluorine tin oxide
substrate by Sputtering system. The morphological properties of CdS/CdTe solar
cell structure with MoO3 buffer layer have been evaluated by means
of scanning electron microscope (SEM) and atomic force microscopy (AFM)
measurements. In addition, the cell device was fabricated to obtain electrical
output parameters of both the traditional CdTe-based cell and CdTe cell with
MoO3 buffer layer. The current‒voltage measurements were carried out
at room temperature under both dark and air mass 1.5 global radiations. The
energy conversion efficiency value has been obtained for traditional cell and
the cell with MoO3 buffer layer as 8.93% and 10.31% 1 Sun,
respectively. It was observed that the integration of MoO3 layer
into CdTe-based solar cell increased cell efficiency by 15.45%.

Bu çalışmada, MoO3
tampon tabakasının CdS/CdTe güneş hücresinin verimliliği üzerine etkisi
araştırıldı. Cam/FTO/SnO2/CdS/CdTe/Au ve Cam/FTO/SnO2/CdS/CdTe/MoO3/Au
olmak üzere iki adet numune üretildi. MoO3 tabakası CdTe ve arka
kontağın metal elektrotu arasına tampon tabaka olarak büyütüldü. Güneş
hücreleri cam/flor katkılı kalay oksit alttaş üzerine Sıçratma (Sputtering)
sistemi ile büyütüldü. MoO3 tampon tabakası içeren CdS/CdTe güneş
hücresinin morfolojik özellikleri atomik kuvvet mikroskobu (AFM) ve taramalı
elektron mikroskobu (SEM) ölçümleri ile incelendi. Ayrıca, güneş hücre
yapılarının elektriksel çıkış parametrelerini belirlemek için hem geleneksel CdTe-bazlı
güneş hücresinin hem de MoO3 tabakası içeren CdTe-bazlı güneş
hücresinin fabrikasyonları yapıldı. Akım-voltaj ölçümleri oda sıcaklığında
karanlık ve 1.5G ışık altında yapıldı. Enerji dönüşüm verimlilik değeri 1
Güneş’de geleneksel ve MoO3 tabakası içeren güneş hücreleri için
sırasıyla %8.93 ve %10.31 olarak elde edildi. MoO3 tabakasının
CdTe-bazlı güneş hücresine entegrasyonunun hücre verimliliğini %15.45 oranında
arttığı gözlemlendi.
