An accurate and straightforward estimation of solar cells modules parameters from the manufacturer’s datasheet is essential for performance assessment, simulation, design, quality control. In this work, a simple efficient technique reported to extract modules, namely ideality factor (n), series resistance (Rs), shunt (Rsh), photocurrent (Iph) saturation current (Io), information. The method bas...

Impedance spectroscopy (IS) is a straightforward experimental technique that commonly used to obtain information about the physical and chemical characteristics of photovoltaic devices. However, nonstandard behavior perovskite solar cells (PSCs), which are heavily influenced by motion mobile ion vacancies, has hindered efforts consistent theory PSC impedance. This work rectifies this omission d...

Herein, the organic semiconductor methyl orange (MO), is investigated for the first time for its electronic applications. For this purpose, Al/MO/n-Si heterojunction is fabricated through economical cheap and simple “drop casting” technique. The currentvoltage (I-V) measurements of the device are made at room temperature under dark conditions. The I-V characteristics of Al/MO/n-Si junction exhi...

An organic bulk heterojunction (BHJ) was fabricated using a blended film containing Copper (II) tetrakis(4cumylphenoxy)phthalocyanine (Tc-CuPc) along with [6,6]-Phenyl C61 butyric acid methyl ester (PCBM). Weight ratio between TcCuPc and PCBM was 1:1. The electrical properties of TcCuPc:PCBM BHJ were examined. Rectifying nature of the BHJ was displayed by current-voltage (I-V) curves, recorded ...

In the pursuit of high injection current diode nanodevices, entire one-dimensional (1D) ZnO coaxial nanostructures with p-n homojunctions is one of the ideal structures. In this study, we synthesized entire 1D ZnO-based coaxial homojunction diodes with p-type Ag-doped ZnO (SZO) nanostructure shells covering n-type Ga-doped ZnO (GZO) nanopagoda (NPG) cores by a metal-organic chemical vapor depos...

Temperature-dependent electrical characterization of Pt/n-GaN Schottky barrier diodes prepared by ultra high vacuum evaporation has been done. Analysis has been made to determine the origin of the anomalous temperature dependence of the Schottky barrier height, the ideality factor, and the Richardson constant calculated from the I-V-T characteristics. Variable-temperature Hall effect measuremen...

This work elucidates the impact of charge transport on the photovoltaic properties of organic solar cells. Here we show that the analysis of current-voltage curves of organic solar cells under illumination with the Shockley equation results in values for ideality factor, photocurrent and parallel resistance, which lack physical meaning. Drift-diffusion simulations for a wide range of charge-car...
