The photovoltaic (PV) array performance is significantly affected by solar irradiation, temperature and its configuration. Indeed, the array configuration has an impact to modify the series (Rs) and the shunt (Rsh) resistances that appear in its mathematical model. Moreover these resistances are dependent on temperature variation. Hence, the latter can affect I-V and P-V characteristics by modifying...
The possible physical mechanism of ELDRS effect in bipolar transistors for room and low-temperature irradiation is described. The ELDRS-free device at room temperature suffers on this effect at low-temperature irradiation.
Photovoltaic Systems are gaining importance rapidly. The performance of the photovoltaic system is hugely dependant on atmospheric conditions. The performance evaluation of the PV systems before on site installation is costly and time consuming. Also, MPPT techniques play a vital role in photovoltaic systems, however on site testing of MPPT techniques is somehow difficult. A PV simulator can be used...
In this paper simulation on the effects of low energy electron radiation and high temperature on the current-voltage (I-V) characteristics of Ni/4H-SiC Schottky diode were investigated. I-V characteristics of the Ni/4H-SiC Schottky diode were simulated based on thermionic emission theory using Silvaco Atlas Technology-computer-aided-design (TCAD) simulation tool. It was found the decrease in the forward...
In our work we observe the light behavior before and after light-induced degradation of amorphous/microcrystalline (a-Si/μc-Si) tandem silicon-based solar cells. We show that during light-induced degradation the efficiency increases for illumination levels lower than standard test condition illumination. Additionally we examine the temperature coefficient of the open circuit voltage, short circuit...
Solar photovoltaic (PV) energy is becoming an increasingly important part of the world's renewable energy. In order to develop efficient technology for effective energy extraction from a solar PV system, this paper investigates and compares typical maximum power point tracking (MPPT) control strategies used in solar PV industry. This paper focuses especially on how sampling rate and time delay influence...
The purpose of this work is to study the effect of X-ray irradiation on pn junction power diode. The diodes were designed and fabricated using standard CMOS technology. Irradiation with exposure energy of 70 keV and various exposure times (5, 55, and 205 seconds) were applied on the diodes. The temperature dependence of the current-voltage (I–V) characteristics of the diodes was measured in the temperature...
Thiol-capped CdSe quantum dots are synthesized rapidly in aqueous solution assisted by microwave irradiation without any poisonous materials. The growth rate of quantum dots is greatly enhanced in this current microwave synthesis. The narrow size distribution (~30nm) of CdSe quantum dots is similar to the oil samples. The results indicate that the photoluminescence quality of quantum dots is improved...
