Introduction. With the snowballing requirement of renewable resources energy, solar energy has been an area key concern to increasing demand for electricity. Solar photovoltaic gotten a considerable amount consideration from researchers in recent years. Purpose. For generating nearly realistic curves cell model it is needed estimate unknown parameters with utmost precision. The five include dio...

• Non ionic eutectic solvents: phenol-cyclohexanol mixture. SLE phase diagram by DSC experiment. Microscopic structure and hydrogen bonding IR spectroscopy, X-ray diffraction theoretical calculations. deep solvents (type V) have been recently proposed as innovative alternative solvents. Prepared mixing the starting components, their mixtures show strong deviations from thermodynamic ideality. A...

In this work, an efficient solution based on the reducing forms approach is presented to extract five parameters of single-diode model PV generators from their I-V curves. Thus, by number unknown two unknowns, analytical expression current LambertW function will then depend only ideality factor and series resistance, as unknowns predict numerically using non-linear least square technique. The t...

The electrical characteristics and microstructures of $\beta$-Ga$_2$O$_3$ Schottky barrier diode (SBD) devices irradiated with swift heavy ions (2096 MeV Ta ions) have been studied. It was found that SBD showed the reliability degradation after irradiation, including turn-on voltage Von, on-resistance Ron, ideality factor n reverse leakage current density Jr. In addition, carrier concentration ...

Abstract The present paper focuses on the properties of p–Si/ ZnS x Se 1−x (0 ≤ 1) heterojunctions in photodetector applications. heterostructures were fabricated by depositing ZnSSe Si wafer using thermal co-evaporation technique with and ZnSe powders. GIXRD study showed that films cubic phase, prominent peak was shifted composition x. maximum crystallite size found for = 0.8. presence point d...

Ultraviolet band C (UV-C) micro light-emitting diodes (micro-LEDs) provide a high energy light emission of 200–280 nm, which are brilliantly utilized in optogenetics, communications, and fluorescence. However, the limited device efficiency notably restricts grand potential application field. In this work, three types 20 × ?m 2 UV-C micro-LEDs with peak wavelength 269 nm fabricated by different ...

High crystalline quality thick ?-Ga 2 O 3 drift layers are essential for multi-kV vertical power devices. Low-pressure chemical vapor deposition (LPCVD) is suitable achieving high growth rates. This paper presents a systematic study of the Schottky barrier diodes fabricated on four different Si-doped homoepitaxial thin films grown Sn-doped (010) and (001) substrates by LPCVD with fast rate vary...

We report on the fabrication of Bi2Sr2CaCu2Ox (BSCCO) nanostructure films by pulsed laser deposition technique (PLD). The structural and optical properties nanostructured film were investigated. X-ray diffraction (XRD) studies prepared at 6.5 8 J/cm2 showed that are crystalline in nature with orthorhombic phase. Scanning electron microscopy (SEM) investigation confirmed deposited has spherical ...
