In this thesis, the photovoltaic properties of the blended polymer of APFO-G6 havernbeen investigated based on enhancing its absorbance. The structure of the blendedrnpolymer was ITO/PEDOT:PSS/D75:APFO-G6:PCBM/Al. The electrical propertiesrnwere studied using Current Voltage (J-V) characteristics and Impedance spectroscopyrn(IS) measurement. The optical absorption spectrum was measured using UV/VIS/NIRrnSpectrometer. The J-V plot shows the structure has photovoltaic properties.Thernabsorbtion spectrum shows the structure absorbed as needed in the extended visiblernregion of the spectrum. Fill factor and the ef ciency was improved due to incrementrnof absorbance. And according to impedance Spectroscopy measurement, the Cole-rnCole plot shows the depletion resistance and capacitance depend on the bias voltage

Subsurface Intelligence & Critical Mineral Exploration

Modern Geology projects now focus on Machine Learning in Mineral Targeting, Carbon Capture & Storage (CCS) Geologic Modeling, and Critical Mineral Systems (Lithium, REEs). If your research involves Hydrogeological Connectivity, Seismic Inversion, or Geotechnical Site Characterization, ensure your analysis follows the JORC or NI 43-101 reporting standards and utilizes robust 3D Subsurface Visualization and Geochemical Fingerprinting frameworks.
