One type of hole transport material (HTM) used in perovskite based solar cells is copper iodide (CuI) thin film. CuI is inexpensive and has high mobility compared to other HTMs commonly used in perovskite based solar cells. However, diisopropylsulfide solvent, which is used to dissolve CuI in the preparation process, is a malodorous and toxic compound. Therefore, the objective of this research was to develop a synthesis method for CuI thin film with in-situ spraying, a low- cost, safe and easy fabrication method. As precursor solution, CuSO45H2O was dissolved in ammonia and KI aqueous solution. The precursor solution was then sprayed directly onto a glass substrate with appropriate temperature to form CuI film. The prepared thin films were characterized by X-ray diffractometer, UV-Vis spectrophotometer, scanning electron microscope and four-point probes to study their properties.[/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]Copper iodides (CuI),Four point probe,High-efficiency solar cells,Hole transport materials,Precursor solutions,Preparation process,UV-Vis spectrophotometers,X ray diffractometers[/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][/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/10.1088/1742-6596/739/1/012050[/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]
