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

The most interesting problem to be discussed in electrical physics is one-way electric circuits. In this work, the researchers constructed an experimental setup for determining the time constant of DC resistors and capacitors using the open-source Arduino UNO hardware platform. Arduino UNO was a signal generator for data collection systems and a simple signal visualization instrument. Experiments were carried out using an analog oscilloscope combined with theoretical calculations. The results show that, on a spreadsheet, the data processing and fitting of the curves for the six Resistor and Capacitor test sets yielded values determined by the component tolerances. The researchers believe that the design of this equipment and software demonstrates the recommended suitability, making it flexible for use in teaching and learning in laboratory contexts.

Abstract

Abstract One of the most fascinating areas of physics is likely optics. However, it also includes some of the phenomena that students find to be less clear-the light spectra produced by light diffraction. The experimental analysis of light spectra to evaluate radiation bodies typically requires specialized and expensive equipment that is typically out of the price range for schools. Few teachers are proficient in measuring the wavelengths of light in a spectrum. In this study, we describe a low-cost, straightforward setup that can measure light spectra accurately enough to be utilized in physics and chemistry lectures. We demonstrate how the shareware program Tracker, which is frequently used to teach mechanics, may be used to measure wavelengths with a resolution of roughly 2 nm. Several methods are also available for calibrating various setups, depending on the level of accuracy required. Keywords optics, spectrum, experimental, wavelength. Abstrak Optik mungkin adalah salah satu topik paling menarik dalam fisika. Namun, itu juga mengandung beberapa fenomena yang kurang dipahami oleh siswa-spektrum cahaya yang diperoleh dari difraksi cahaya. Studi eksperimental spektrum cahaya untuk mempelajari benda beradiasi biasanya membutuhkan peralatan canggih dan mahal yang biasanya tidak terjangkau oleh sekolah, dan hanya sedikit guru yang mengetahui cara mengukur panjang gelombang cahaya dalam spektrum. Dalam karya ini, kami menyajikan pengaturan yang sederhana dan murah, dengan akurasi yang cukup untuk mengukur spektrum cahaya yang akan digunakan baik di kelas fisika maupun kimia. Kami menunjukkan bagaimana Pelacak perangkat lunak freeware, yang biasa digunakan untuk mekanika pengajaran, dapat berfungsi untuk mengukur panjang gelombang dengan resolusi sekitar 2 nm. Beberapa pendekatan untuk kalibrasi pengaturan yang berbeda juga disediakan, tergantung pada tingkat akurasi yang diharapkan. Kata kunci optik, spektrum, eksperimental, panjang gelombang.DOI: http://dx.doi.org/10.23960/jpmipa/v24i1.pp28-38
