Abstrack Objective. The use of silicon solar cells is still relatively expensive and also uses harmful chemicals in the manufacturing process. Therefore it is necessary to develop alternative solar cells that are based on inexpensive and environmentally friendly, such as DSSC (Dye-Sensitized Solar Cell). The use of DSSC is very well prepared because of the simple manufacturing process, low cost, and organic-based. Based on this, the development of DSSC requires the use of dye from anthocyanin extracts from natural materials that are widely available in the environment. Materials and Methods. This study aims to determine the characteristics of DSSC using rosella flower extracts with variations in the distance of the light source to DSSC. The trademarks measured are current and voltage values and cell efficiency. As the light source used is a 150-watt halogen lamp. Light sources are placed at a distance of 10 cm, 20 cm, and 30 cm. Results. Characterization of DSSC voltage and current values using a halogen lamp with a distance of 10 cm to DSSC is more significant than a length of 20 cm and 30 cm. The test results show that the efficiency of cells within 10 cm of DSSC is the best result of maximum current (Imax) of 0.08 mA, maximum voltage (Vmax) of 121.7 mV. Conclusion. The performance of DSSC is influenced by the distance of the light source used against the cell. This difference in efficiency value is caused by the higher intensity of the light to the battery, the closer the distance of the light source, the higher the depth of the sun to produce an immense efficiency value.

Dual Functions

PurposeFlexible hydrogenated amorphous silicon (a-Si:H) solar cells have many advantages, including lower weight, good flexibility and light sensitivity. Moreover, a-Si:H solar cells can be used as sensors, as indoor light sources and can also generate electricity. These solar cells are suitable for the design of portable systems and curved materials. The purpose of this study was to integrate flexible a-Si:H solar cells and wearable technology and to apply the dual functions of photovoltaics and photo sensors to smart clothing and eyewear.Design/methodology/approachThe integration of flexible a-Si:H solar cells and tri-colour light-emitting diodes (LEDs) was used to develop smart auto-flashing clothing. In addition, we combined flexible a-Si:H solar cells and twisted nematic (TN) liquid crystal (LC) cells to design smart self-activation eyewear.FindingsThe maximum power resistance value of flexible a-Si:H solar cells was used to deduce the equation of solar cell voltage value generated by different percentages of SUN (100% SUN means 100 mW/cm2). A solar cell was used as a photo sensor that connects a resistor in a series to the Arduino to detect the voltage value, and then different percentages of SUN are calculated from the equation. Applying the deduced equation to the smart phone APP and Arduino code, we developed a human–machine interface (HMI) to facilitate user operation.Originality/valueIn this study, the flexible a-Si:H solar cell performs the function of not only photovoltaic power generation but also that of a photo sensor. The smart auto-flashing clothing is suitable for traffic guides, joggers and people engaging in other night activities. This smart self-activating eyewear can adjust to light and protect the eyes.

Solar or solar energy can be an alternative source of energy in the future, where solar energy can be converted into electrical energy by utilizing the photoelectric effect that occurs in photovoltaic components or solar cells. Solar cells or photovoltaic components can convert sunlight into electrical energy that can be used directly by the load or stored in a battery, a kind of electrochemical device that can store electrical charges in the form of chemical energy. The electrical energy generated by the solar cell is influenced by the intensity of light received by the sun. To gain the desired power and voltage, the solar cells are connected in series and parallel into a solar cell module. 2N3055 & MJ2955 transistor based solar panels are the basic materials for designing alternative power generation. In the process of manufacture, this solar panel utilizes the components of used components that are still feasible to use, so it can be used to be the appropriate technology to produce a solar panel that utilizes solar energy in the form of sunlight and solar heat. In this study also conducted experiments using glass components as a reflection effect from light sources.

This paper numerically explores the possibility of ultrathin layering and high efficiency of graphene as a back surface field (BSF) based on a CdTe solar cell by Personal computer one-dimensional (PC1D) simulation. CdTe solar cells have been characterized and studied by varying the carrier lifetime, doping concentration, thickness, and bandgap of the graphene layer. With simulation results, the highest short-circuit current (Isc = 2.09 A), power conversion efficiency (h = 15%), and quantum efficiency (QE ~ 85%) were achieved at a carrier lifetime of 1 × 103 ms and a doping concentration of 1 × 1017 cm−3 of graphene as a BSF layer-based CdTe solar cell. The thickness of the graphene BSF layer (1 mm) was proven the ultrathin, optimal, and obtainable for the fabrication of high-performance CdTe solar cells, confirming the suitability of graphene material as a BSF. This simulation confirmed that a CdTe solar cell with the proposed graphene as the BSF layer might be highly efficient with optimized parameters for fabrication.

Crucial Parameter

In this paper, a randomly distributed plasmonic aluminum nanoparticle array is introduced on the top surface of conventional GaAs thin-film solar cells to improve sunlight harvesting. The performance of such photovoltaic structures is determined through monitoring the modification of its absorbance due to changing its structural parameters. A single Al nanoparticle array is integrated over the antireflective layer to boost the absorption spectra in both visible and near-infra-red regimes. Furthermore, the planar density of the plasmonic layer is presented as a crucial parameter in studying and investigating the performance of the solar cells. Then, we have introduced a double Al nanoparticle array as an imperfection from the regular uniform single array as it has different size particles and various spatial distributions. The comparison of performances was established using the enhancement percentage in the absorption. The findings illustrate that the structural parameters of the reported solar cell, especially the planar density of the plasmonic layer, have significant impacts on tuning solar energy harvesting. Additionally, increasing the plasmonic planar density enhances the absorption in the visible region. On the other hand, the absorption in the near-infrared regime becomes worse, and vice versa.
