The three dimensional photovoltaic cell is revolutionary silicon solar cell, design to maximize the conversion of sunlight into electricity. It is like container rather than plane conventional solar cell and has ‘High Efficiency Design to produce 200% of the Power Output of the Conventional Solar Cells’. Three dimensional solar has a special feature on the surface to capture more light in the morning and evening hours, as well as in the winter months when the sun is not directly overhead. Unlike conventional solar cells where electrical contact wires run on the top of the cell, blocking sunlight, three dimensional solar cell use a network of contact wires run below the light collector. Solar Tree is energy generating and harvesting tree, in order to increase efficiency “SPIRALLING PHYLLATAXY” technique is applied. It is way of mounting the three dimensional solar panel (leaf) on the top such a way that maximum sunlight incident on it. It can be applied in street lightening system, industrial power supply etc. It is much better than traditional photovoltaic solar system in area point of viewandalso more efficient. It is perfect solution for future energy needandFibonacci Sequence SolarTree is one of advance solar tree. After using three dimensional solar cell in solar tree, the investment payback period of solar panel systems is40%more than conventional solar panel systems.

With the dramatic increase of photovoltaic (PV) module installation in solar energy-based industries, the methods for recovering waste solar generators should be emphasized as the backup of the PV market for environmental protection. Crystalline-silicon accounts for most of the worldwide PV market and it contains valuable materials such as high purity of silicon (Si), silver (Ag), copper (Cu), tin (Sn), and lead (Pb). This study can provide an efficient recycling process for valuable materials resourced from waste crystalline-silicon PV module, including Si in the PV cell, and Ag, Cu, Pb, Sn, in PV ribbon. As tempered glass and Ethylene Vinyl Acetate (EVA) resin were removed, the module was separated into two materials, PV ribbon and PV cell. For PV cell purification, Si with purity at 99.84% was recovered by removing impurities such as aluminum (Al) and Ag by two-step leaching and dissolving the impurities. For PV ribbon recovering, purified metal or metal oxide was obtained through the processes of leaching/polishing, extraction, and chemical precipitation. In the polishing process, 99.5% of copper wire was collected. The purities of final products are 99.7% for CuO, 99.47% for PbO, 99.68% for SnO2, and 98.85% for Ag respectively.

In today’s world, solar panel is one of the major sources for generating powerdirectly from the sunlight by using electronic processes and there is no greenhouseemission in photovoltaic cell as it does not require any other source of fuel like coal,natural gas, oil, nuclear power systems. Hotspot is one of the main causes ofphotovoltaic cell which occurs due to the dissipation of power in shaded cells. In theexisting literature, the hotspot in solar panel is detected by using various algorithmsand techniques but it does not improve accuracy, performance, temperaturedistribution, problem like overfitting and underfitting also exists. To overcome that,the proposed work deals with capturing the hotspot as thermal image through aninfrared camera which is mainly used for temperature distribution. For identifyinghotspot, the features like shade, correlation, contrast, energy, entropy, homogeneity,prominence, sparse are extracted using sparse reconstruction and GLCM algorithms.The features are given to the classification algorithm named as Extreme LearningMachine which gives the good generalization performance and improves accuracyhigher when compared to other algorithms. The overfitting and underfitting problemcan also be rectified by using these algorithms. Finally using extreme learningmachine, the percentage of hotspot in photovoltaic cell can be identified.

This paper consists analysis on performance enhancement of solar photovoltaic cell by using reflecting and cooling system. The performance of PV (photovoltaic) module is strongly dependent on its surface temperature and solar radiation strikes on PV panel. It is necessary to study possible way for maintaining the appropriate temperature for solar panels and make system that will help to strikes maximum solar radiation on panel. High solar radiation and ambient temperature lead to an elevated photovoltaic cell operating temperature, which affects its lifespan and power output adversely. To enhance the electrical performance of the PV module we make one system which consists of two mirrors as a reflector placing beside solar panel and cooling system consists of pipe placed on upper area of solar panel. At time of sunrise and sunset low solar radiation is fall on solar panel, so reflecting system increase the intensity of solar radiation fall on solar panel. At noon time or afternoon the temperature of solar panel is increases it will decrease the efficiency of solar panel to minimize that cooling system is introduced that controlled the surface temperature.

The Impact

Photovoltaic modules behave extraordinarily by transforming part of the visible spectrum into electrical energy, and their efficiencies are affected by the nature of radiation (light) reaching them. When light strikes a photovoltaic cell, this light may go through the cell without been absorbed if it is too energetic or if the light possesses low energy it will be absorbed by the cell and cause the electrons to twist and vibrate in their bonds without dislodging them, hence causing the cell to heat up which ultimately leads to a decrease in its overall efficiency. This study is aimed to investigate how photovoltaics respond to different wavelengths of light. For the study to achieve its aim, colour filters were used to ensure that only a particular wavelength of light reaches the photovoltaic module at a time. In the process of collecting data from the solar panel, the solar panel was placed horizontally flat on a platform one meter above sea level facing the sun. Data was first obtained from the solar panel without the filters and after that with the filters placed one at a time and data collected accordingly. The amount of solar power and solar flux anytime a different colour filter was placed on the solar panel were measured. Among the coloured filter used yellow produced the highest efficiency, while blue produced the least efficiency. However, the solar panel was still more efficient when exposed to the natural spectrum.

To solve the wide range of the output voltage, difficult storage and not unified interface of solar cell, a novel solar charging system was proposed. The system consists of the solar panel, the voltage regulator circuit, the battery charge management circuit, the lithium battery, the booster circuit and the USB output circuit. The voltage regulator circuit can convert the output voltage of solar panel into 5V. By means of the charge management circuit, the energy is stored in the lithium battery, and it can be provided to the load via the booster circuit and USB interface, which can achieve the goal of the conversion, storage and utilization from solar to electrical energy. Under the condition of effective illumination between 10:00 and 16:00, the solar charging system was tested for 7 days. Experimental results show that the output voltage always maintained at 5V during the test. The output voltage of lithium battery reaches to 4.2V after four hours, and the output voltage of USB port always stabilizes at about 5V.

Gelatin cross-linking has recently been discovered to be a very appealing method of producing gelatin-based films. The current research looks at various commercial gelatin (type B) films to improve their physical qualities. Bunium alpinum and bunium incrassatum essential oils (EOs) in two quantities (5% and 25%) were added to the films, which showed substantial biological activity (antibacterial, antioxidant, antihemolytic, and anti-inflammatory). According to electronic scanning microscopy, the basic gelatin matrix had changed and there were multiple dense spots on the cross-linked films. The particles appear to be more bonded in an isotropic form. Infrared spectroscopy cannot provide substantial accuracy on the new characteristics and chemical interactions formed due to the complex system of both gelatin and EOs. According to the UV transmission test results, adding EOs to gelatin films improves the barrier properties against UV rays and prevents UV light transmission. Finally, the swelling water test revealed that included EOs in the film composition reduce the film's swelling.
