Abstract

In this study, the effect on the efficiency of CdS/CdTe solar cell with MoO 3 buffer layer was examined. Two sample was grown as Cam/FTO/SnO 2 /CdS/CdTe/Au and Cam/FTO/SnO 2 /CdS/CdTe/MoO 3 /Au. MoO 3 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 MoO 3 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 MoO 3 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 MoO 3 buffer layer as 8.93% and 10.31% 1 Sun, respectively. It was observed that the integration of MoO 3 layer into CdTe-based solar cell increased cell efficiency by 15.45%.

Özet

Bu çalışmada, MoO 3 tampon tabakasının CdS/CdTe güneş hücresinin verimliliği üzerine etkisi araştırıldı. Cam/FTO/SnO 2 /CdS/CdTe/Au ve Cam/FTO/SnO 2 /CdS/CdTe/MoO 3 /Au olmak üzere iki adet numune üretildi. MoO 3 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. MoO 3 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 MoO 3 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 MoO 3 tabakası içeren güneş hücreleri için sırasıyla %8.93 ve %10.31 olarak elde edildi. MoO 3 tabakasının CdTe-bazlı güneş hücresine entegrasyonunun hücre verimliliğini %15.45 oranında arttığı gözlemlendi.
