Their optical and electrical characteristics were studied by optical UV-Vis spectroscopy and Hall effect measurements, which indicate that the optical transparency and charge carrier density increase with the addition of small concentration of Al (0.8 mol%) but decrease with further addition. These characteristics is consistent with the crystal structure and nano-morphology characterization results, performed by means of XRD spectroscopy and Atomic Force, respectively, which show the increase of the proportion of the preferred crystal orientation (002) and reduction of surface roughness at small Al concentration. The effect of Aluminum concentration on photovoltaic characteristics in hybrid solar cells based on P3HT:PCBM blend polymer by utilizing this AZO layer has also been studied. The solar cell performance improves by using this AZO layer with small Al concentration of about 0.8 mol% as its electron transport layer. © 2012 American Institute of Physics.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Doped zno,Electron transport layer,Hybrid solar cell,Sol-gel process[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1063/1.4730726[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
