Solar cells known so far still have many shortcomings in terms of Mounting and positioning against the sun, so the performance of solar cells in Battery charging is not maximal. There fore additional tools are required As a support for the solar cell to work optimally, and the electric current Is generated larger. Sunlight tracking with LDR system as As the sensor to direct to the sunlight rays will be compared With a passive system. Atmega16 as motor control and auto carger, LDR As a recipient of sunlight, DC motor as a direction player Sunlight. Solar cell is used with a capacity of 20 WP.And auto carger system using microcontroller is more cost-efficient and installation. After the two systems will be compared first in order Know the difference how much power generated by solar system Cell using a tracker and a passive one. Data retrieval will be Implemented for one week with sytem tracker and one week with Passive system. With the results of data to be in can be analyzed system comparison And known how much efficiency. Expected with a solar tracker system Cell can increase battery charging faster than with Passive position.

The research was conducted to explain how to design a simulation of Solar tracker on Wind-Solar hybrid technology. The simulation were carried out with proteus software simulation. Solar tracker has four LDR sensors and an Arduino Uno Microcontroller which assist the Solar tracker to estimating position of the sun to use a servo motor for solar cell movement. For the result, When the upper light intensity (LDR 1 and LDR 2) is greater than the bottom (LDR 3 and LDR 4), solar cell will move upwards, and vice versa. When the light intensity of the left (LDR 1 and LDR 3) is greater than the right (LDR 2 and LDR 4), solar cell will move to the left, and vice versa. From the research, it could concluded that Solar Tracker can be applied to Wind-Solar technology solar cells

Carbon nanotube bundles were precisely grown atop a p-type silicon wafer that had been treated with catalysts to produce geometries that resemble three-dimensional nano-models to extract more power from the sun. The embedded carbon nanotubes bundles on silicon wafer promise more opportunity for each photon of sunlight to interact with resulting solar cell, as a result of increase of surface area available to produce electricity. The paper discusses morphology of grown nanotubes on silicon wafer along with future prospects of Si-CNTs fabricated solar cells.

AbstractIt is known that the a-Si:H solar cell with H-diluted i-layer (p-iH-n) exhibits a better stability under AMI light exposure than the non-diluted solar cell (p-i-n). Recently, Wang et al. found that the a-Si:H solar cell when inserting a thin H-diluted i-layer between the p- and the i-layer (p-iH-i-n) shows the same stability as a p-iH-n solar cell after 600 hours light soaking. It was suggested that the stabilization of a H-diluted a-Si:H solar cell is through controlling its p/i interface. In this work, we report the electroluminescence (EL) measurements of a-Si:H solar cells with p-iH-n, p-iH-i-n and p-i-n structures made in identical conditions except the difference in H-dilution processing. EL spectra in a wide range of temperature indicate that the defect-band emission can be controlled through a thin H-diluted i-layer near the p/i interface region, but the main-band emission depends more on the diluted i-layer thickness. According to the temperature dependence of the EL efficiency, the valence band-tail width of the active layer in the p-iH-i-n cell is estimated to be about 13% broader than that in the p-iH-n cell. From the total EL intensity as a function of the forward current density, the recombination processes at room temperature are suggested to be a monomolecular type for p-iH-wn, p-iH-i-n, and p-i-n structures.

Nonradiative recombination losses originating from crystallographic distortions and issues occurring upon interface formation are detrimental for the photovoltaic performance of perovskite solar cells. Herein, we incorporated a series of carbamide molecules (urea, biuret, or triuret) consisting of both Lewis base (–NH2) and Lewis acid (–C=O) groups into the perovskite precursor to simultaneously eliminate the bulk and interface defects. Depending on the different coordination ability with perovskite component, the incorporated molecules can either modify crystallization dynamics allowing for large crystal growth at low temperature (60°C), associate with antisite or undercoordinated ions for defect passivation, or accumulate at the surface as an energy cascade layer to enhance charge transfer, respectively. Synergistic benefits of the above functions can be obtained by rationally optimizing additive combinations in an all-in-one deposition method. As a result, a champion efficiency of 21.6% with prolonged operational stability was achieved in an inverted MAPbI3 perovskite solar cell by combining biuret and triuret additives. The simplified all-in-one fabrication procedure, adaptable to different types of perovskites in terms of pure MAPbI3, mixed perovskite, and all-inorganic perovskite, provides a cost-efficient and reproducible way to obtain high-performance inverted perovskite solar cells.

Irradiance Spectrum

The spectral response of the Si solar cell does not coincidence with the sun irradiance spectrum, so the efficiency of the Si solar cell is not high. To improve the Si solar cell one try to make use of most region of the sun spectrum by using dyes which absorb un useful wavelengths and radiate at useful region of spectrum (by stock shift). Fluorescence's dye is used as luminescent concentrator to increase the efficiency of the solar cell. The results show that the performance efficiency and out power for crystalline silicon solar cells are improved.

This article aims to analyze students' understanding of the purpose of solar cell technology. Because the role of students is very important in developing one of the renewable energies that is solar cells. There are still many people who have not seen other benefits from the sun, as well as ways to use solar energy for other processes, such as the use of solar cells in households and so on. Most of humans have not seen other ways and benefits of solar energy. So that to socialize the use of solar cell technology, students need to understand how important solar energy is as a renewable energy and how to use it. The method used in this study used quantitative descriptive, with the sample of 2019 class of physics education students.Keywords: Solar cell, Environment, Renewable.

Among the different ways to improve the performances of light harvesting inside solar cells, multilayer configuration can be used. The bandgap of each single layer will contribute to absorption in a well defined wave-lengths range, enhancing the overall performances. Here, we investigate such performances in the case of solar cells made by two layers: a silicon one, and a SiC-based layer, and show the increasing of electrical working by means of computer simulations. These simulations are based on Finite Difference Time Domain (FDTD) for the optical calculations, on one side, and the Finite Element Method (FEM) for the electrical ones, on the other. The main goal is to show the enhancement of the electrical performances in heterostructure solar cells. In this paper, we investigate the influence of each different structure on the optical and electrical response. Our results show the influence of the device structures, in particular, the enhancement of the UV-ligth absorption inside the solar cell. Moreover, the difference structures allow us to show an improvement in the harvesting charge carrier by the heterojunction.
