“…Selain itu, distribusi suhu pada fotovoltaik sangat mempengaruhi pada kinerja dan kualitas fotovoltaik [13]. Penurunan kinerja fotovoltaik karena hilangnya output daya dari fotovoltaik dan kenaikan termal dapat terjadi karena peningkatan tegangan termal [14]. Banyak investigasi yang berhubungan dengan pendinginan fotovoltaik telah dipresentasikan secara eksperimental dan numerik [15].…”

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.

“…The photoelectric effect, or the electromagnetic radiationinduced emission of electrons from a metal surface [11], is one of the quantum mechanical phenomena that may be empirically proven in beginning physics classes [12]. The wavelength of the incoming radiation determines its emission, not its strength [13].…”

In this project, a tool that can explain phenomena involving the photoelectric effect at laboratory scales is being developed. The purpose of this tool is to help users understand that the photoelectric effect, which causes electrons to move from a source of a negative voltage to a source of positive voltage, is not affected by light intensity but rather by a light source's frequency and wavelength. A photodiode is employed in the creation of this device as a light sensor, and when exposed to light, it moves electrons from the cathode to the anode, causing an electric current to flow. The voltage is delivered to the cathode, which is where the electrons leave, to calculate the stopping voltage. A graph showing the connection between the ADC value and the sensor output voltage is produced from the ongoing data gathering. Our results show that each color spectrum has a distinct voltage supplied to the photodiode leg (cathode). Additionally, the output voltage measured for each distinct wavelength was decreased the lower the photodiode's light intensity was.

“…Electronic structure is a major key in understanding the properties and behavior of matter. In the context of P-type amorphous silicon nanowires, their electronic structure is of particular interest because it allows for p-type conductivity [17]. However, when amorphous silicon is converted into nanowires with P-type characteristics, meaning 'holes', there is a dramatic change in their conductivity properties [18].…”

Silicon nanowires can improve broadband optical absorption and reduce the radial carrier collection distance in solar cell devices. The disordered nanowire arrays grown by the Plasma-Enhanced Chemical Vapor Deposition method are attractive because they can be embedded on low-cost substrates such as glass, and are compatible with large areas. Here, we experimentally demonstrate that reactive Hydrogen ions with increasing concentrations are doped to construct nanowire architectures in amorphous silicon solar cells. Similar to our investigated planar a-Si: H layers, the amorphous silicon nanowires exhibit a loss function coefficient of about 105/cm. From the reflectivity function, it can be shown that the nanostructures can offer a reliable carrier pool. Our results show that the addition of nanowires can increase the efficiency of a-Si solar cells from 1.11% to 1.57%. The input-photon-to-current conversion efficiency spectrum shows effective carrier collection from 1.2 to 2.2 eV of incident light and the nanowire devices show an increase in short-circuit current of 15% with amorphous Si and 26% with nanocrystalline Si compared to planar devices appropriate.
