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.

Abstract

Dalam studi ini, kami menyaajikan investigasi eksperimental terhadap kinerja sel surya yang digabungkan dengan peredam panas. Pengaturan eksperimental dalam ruangan dirancang dan dirakit untuk menyelidiki dampak penggunaan sistem pendingin peredam panas pada kinerja sel surya. Lampu halogen digunakan untuk mensimulasikan radiasi matahari dan penelitian dilakukan pada nilai radiasi matahari yang berbeda. Selain itu, penelitian dilakukan pada udara alami dan paksa untuk mendinginkan peredam panas. Hasil penelitian menunjukkan bahwa penggunaan sistem pendingin peredam panas meningkatkan kinerja sel surya. Suhu sel surya menurun sekitar 5,4 % dan 11 % masing-masing dengan menggunakan sistem pendingin peredam panas pada udara alami dan udara paksa di atas peredam panas. Selain itu, efisiensi dan daya sistem sel surya meningkat sekitar 16% saat sistem pendingin peredam panas digunakan.In this study, we conducted an experimental investigation of the performance of a solar cell coupled with a heat sink in a relatively simple system. An indoor experimental setup was designed and assembled to investigate the impact of using a heat sink cooling system on the performance of solar cell performance. Halogen lamps are used to simulate solar radiation and research is carried out on the value of solar radiation which varies from the highest wavelength to the lowest wavelength. In addition, research was carried out on natural and forced air to cool the heat sink. The results showed that the use of a heat dissipation cooling system increases the performance of solar cells. The temperature of the solar cell was decreased by about 5.4 % and 11 % respectively by using natural air and forced air to overheat sink cooling systems. We believe the efficiency and power of the solar cell system increase by about 16% when a heat dissipation cooling system is used.

Abstract

Malus' law asserts that the square of the cosine of the angle formed between two polarizers is directly proportional to the light intensity after passing through them. In this study, we demonstrate this law using a straightforward configuration. Our method of measuring the polarizer's rotational angle while keeping the other polarizer stationary is innovative. It involves manually attaching a multi-turn potentiometer to one of the polarizers. The Arduino board is connected to the potentiometer and light sensor used to detect the intensity of transmitted light, allowing for the measurement of light intensity as a function of rotational angle. Additionally, we think that the configuration as it is now can be helpful in physics laboratory classes. It can also be demonstrated by using it during lectures.

Abstract

In the study, we analyzed the acidity level of coffee grounds as an alternative catalyst for bio-battery energy sources, investigated how coffee grounds work as an alternative catalyst, and investigated how power is generated from variations in coffee grounds. This study used four variations of coffee grounds. Data collection was carried out by taking pH data or acidity level, voltage data, and also the length of time the LED was on from each variation of coffee grounds. The results showed that the civet arabica, original arabica, mongoose robusta, and original robusta coffee grounds respectively had pH values of 5, 5.15, 5.36, 5.6. Then the voltage is 1.35 volts, 1.27 volts, 1.11 volts, 0.994 volts. And the LED time is 417 hours, 414 hours, 409 hours, 404 hours. So that from the results obtained there is a significant relationship between the pH value and the voltage and power, that is, the smaller the pH value, the greater the voltage and power generated.
