Abstract

In this work, the imbalances in band gap energy between p-window layer and intrinsic layer (p/i interface) in p-i-n type solar cells to suppress charge recombination adopting with the addition of buffer layer, at p/i interface, namely solar cell structures without buffer (Cell A) and with buffer (Cell B). Using well-practiced AFORS-HET software, performances of Cell A and Cell B structures are evaluated and compared to experimental data. A good agreement between AFORS-HET modelling and experimental data was obtained for Cell A (error = 1.02%) and Cell B (error = 0.07%), respectively. The effects of dopant concentrations of the p-type and n-type were examined with respect to cell B for better performance by analysing the energy band diagram, the electric field distribution, the trapped hole density, the light J-V characteristics, and the external quantum efficiency. The simulated results of an optimised Cell B showed that the highest efficiency of 8.81% (VOC = 1042 mV, JSC = 10.08 mA/cm2, FF = 83.85%) has been obtained for the optimum dopant values of NA = 1.0 x 1019 cm-3 and ND = 1.0 x 1019 cm-3, respectively. A comparison between experimental data and simulation results for Cell B showed that the conversion efficiency can be enhanced from 5.61% to 8.81%, using the optimized values

Abstract

In this work, it is reported that the development of technology makes the need for electrical energy in recent years has increased very rapid. PT Multidaya Prima Elektrindo is a company engaged in power generation using gas energy sources, namely the Gas Engine Power Plant. with a capacity of 2x6 MW. The energy produced by this plant will later be distributed to consumers through the State Electricity Company. Along with its use, generating machines continuously work for long periods of time. If this continues, there will be overheating of the engine which can cause a trip to the engine, to prevent a trip on the engine, monitoring the cooling system on the engine can prevent overheating which can cause a trip on the engine. By using a cooling system, the performance of the engine at the generator in generating energy is optimal. The processed data is weather data around the PLTG location and characteristic data from the gas turbine. The results of data processing are taken into consideration in choosing a cooling system. Other processing data in the form of cooling load is then used to design the components of the cooling system that will be applied. The results of the study show that reducing the outside air temperature entering the gas turbine compressor to 22 °C, can increase the output power of the PLTG gas turbine by more than 10 MW.

Abstract

Photoanode is a component of the dye-sensitized solar cell (DSSCc) which is synthesized from metal oxide semiconductor material with nanoparticle size deposited on transparent conductive glass. TiO2 powder was synthesized by mixing 20 mL of Titanium (III) chloride (TiCl3) with 100 mL of the equator and stirred for 1 hour. TiO2-SnO2 thin films have been successfully synthesized using the coprecipitation method and coated on ITO (Indium Tin Oxide) substrate by doctor-blade technique. The structure and morphology of the films were investigated by XRD and SEM respectively. The analysis of optical characteristics shows that the absorbance of TiO2 photoanode is in the wavelength range of 300-600 nm while SnO2 is in the wavelength range of 300-870 nm. The results showed that the synthesized film with SnO2 had a stronger anatase formation than the film with pure TiO2. Finally, incorporating SnO2 into the TiO2 matrix is an effective strategy to improve the overall properties of solar cells in future applications

Abstract

In this study, we try to propose a simple electronic computational experiment of one-dimensional motion, which combines physics and computer science. Our experimental setup is based on the Raspberry Pi3 model B with the Raspbian operating system. The ultrasonic proximity sensor is the HC-SR04, which can be powered using the +5V DC output of the Raspberry Pi. An ultrasonic proximity sensor is used to obtain the position of a selected target along a linear path, with a Raspberry Pi and simple Python code. Another simple script is proposed to calculate velocity and acceleration and for a graphical presentation of the results. Our results show that motion can be qualitatively and quantitatively defined, and the experiment is suitable for undergraduate students or for younger students

Abstract

In this study, we report the application of a functional dielectric model of scalable ellipsometric spectroscopy to investigate the optical response of materials in the optical spectrum modeling of hydrogenated amorphous silicon. ES is used to obtain the dielectric constant of the data fitting experimental. Then ψ and Δ are obtained from the analysis of the experimental comparison of the valence band and the conduction band state density with the band structure theory for a-Si: H. The analysis results are that for a-Si: H, the density of state model for all electronic transitions is obtained, whose results are consistent with experimental data from ES measurements over the entire photon energy range of 0.5–6.5 eV. Our results demonstrate the high-energy excitons and plasmons for the performance of photovoltaic devices in a-Si: H. Overall, we believe our methodology can study in detail about electron and hole interactions in semiconductors.DOI: 10.17977/um024v7i22022p068

Abstract

In this study, we present examples of solar cells that were subjected to various levels of 60Co gamma radiation. The solar cells we use are mono-crystalline, which has a stable crystal structure and high efficiency compared to polycrystalline. Prior to and during gamma irradiation, the current-voltage characteristics of monocrystalline silicon solar cells under AM1.5 light conditions and their photon spectral currents were examined. The results of the experiment demonstrate that as the dose of gamma radiation increases, solar cell metrics including open circuit voltage (Voc), short circuit current (Isc), and efficiency (η) drop. The photon spectral current demonstrates that as dose gamma is increased, the current decreases at shorter wavelengths  and the defects are primarily produced near the solar cell's surface. Our findings demonstrate the gamma irradiation-induced breakdown of silicon solar cells and the minority carrier lifetime which demonstrates that the minority carrier lifetimes sharply decline with increasing radiation dose.

Abstract

The main objective of this research is to fabricate double-layer hydrogenated amorphous silicon (a-Si:H) using a PECVD by varying the thickness of the active layer. To obtain the thickness of the double active layer, dilution of silane plasma is carried out by hydrogen, with a ratio of hydrogen and silane, R=H2/SiH4 varies, and the deposition time of the active layer, while the n-type and n-type extrinsic layers are fixed for each -each sample. Then on the sample, there is a metal coating on the back which acts as an electrical contact and light reflector. Additionally, each sample was examined or searched for with a sun simulator and sunlight for physical properties, such as thickness morphology, optical properties, such as bandgap, electrical properties, such as electrical conductivity, and I-V characterization of a-Si: H double active layer solar cells. Based on the I-V characterization of the a-Si: H double active layer solar cells that were found in this work, a satisfactory conversion efficiency (8.86%) was found, although the Field Factor of the active layer was still low. While the intrinsic photo response reached 105

Abstract

In this article, we discuss the experimental absorption of radioactive light radiation on various materials using Geiger Muller. Under certain conditions, Geiger Muller can be used to determine the absorption coefficient of a material. The radioactive rays observed in this experiment are gamma rays. Gamma rays are radioactive rays that have no charge so they cannot be deflected by magnetic or electric fields and have the greatest penetrating power. We made several important results on experimental studies of the absorption of gamma radiation passing through matter. Our results relate to the trend of the unexpected, measured intensity of radiation versus the thickness of the absorber, which confuses students and cannot be explained by many laboratory assistants. Finally, we believe that a distribution function is an effective tool for examining the contribution of the build-up factor in the Geiger Muller calculation of the measured radiation intensity.
