Calcium Doped Zno Etl Effect On The Performance Of Inverted P3ht: Pcbm Based Polymer Solar Cell

Abstract

In This Research Study, P3ht:pcbm Bulk Hetero junction (Bhj) Inverted Polymer Solar Cells (Pscs) Were Successfully Fabricated. Calcium-Doped Zinc Oxide Was Prepared Using A Low-Temperature Sol-Gel Process. Their Morphological, Electrical, And Optical Characteristics In Response To Varying Concentrations Of Calcium In Host Zno Were Investigated. The Results Showed That The Inverted Polymer Solar Cell Devices Utilizing Ca:zno Films As Electron Transport Layer Exhibited A Better Performance As Compared With Pure Zno Films. The Inverted Polymer Solar Cells Incorporating A 3% Ca:zno EtlDisplayed A Notably Improved Ef Iciency Of 3.25% Compared To A Pristine Zno EtlEf Iciency Of 1.31%. The Photovoltaic Performance Of The Ipscs With Ca:zno Etls Can Be Attributed To Several Factors, Including Adjustable Band Gaps, High Optical Transparency, Enhanced Electron Mobility, Increased Electrical Conductivity, And Optimized Surface Morphology. The Findings Also Demonstrated Result Shows That The Ca:zno Interfacial Layers Improved Electron Extraction And Successfully Suppressed Photo generated Carrier Recombination Within Solar Cell Devices. This Groundbreaking Development Represents A Significant Step Forward In The Field Of Bulk Hetero junction Polymer Solar Cells With Inverted Structures, Paving The Way For Further Advancements In This Area Of Sustainable Energy Research
