This article aim to be able to take advantage of an electric motor as a net puller on a fishing boat using solar energy. The use of human labor as a net puller requires a large amount of energy and needs a break to be able to do more withdrawal activities, so the number of withdrawals that can be done is very limited. Pantai Jaya fishing groups as partners are among the 20 active fishing groups in the Pasie Nan Tigo sub-district of Koto Tangah subdistrict of Padang City who experience these problems. The problem of this partner can be given a solution in the form of the use of an electric motor as a towing net on a fishing boat. In order not to cause problems in terms of electricity supply, solar energy can be used by using solar cells, so there is no addition of fuel oil. The implementation method given is direct installation and provision of extension materials on the use of solar cell technology and the introduction of components and hand tools. This activity was carried out for two days which included preparation, installation and training, followed by a group of fishermen. The fishing group received a set of solar cells, electric motors, batteries and other accessories and installed them. Based on tests that have been carried out in sunny weather conditions at 300C, a load of 50 kg with a rated voltage at that time 12.4V, motor speed 2.7m / min, 2.4A. Based on the results of these tests indicate that the solar cell system has worked according to the parameters it should. Therefore, it can be said that this activity has been carried out properly and the solar cell system is functioning properly. Participants hope for these activities to be carried out for the following year, because there are still a number of fishing boat groups that are in dire need.

The ramping solar energy to electricity conversion efficiencies of hybrid organic-inorganic perovskite solar cells during the last five years have opened new doors to low-cost solar energy. The record power conversion efficiency has climbed to 19.3% in August 2014 and then jumped to 20.1% in November. In this review, the main achievements for perovskite solar cells categorized from a viewpoint of device structure are overviewed. The challenges and prospects for future development of this field are also briefly presented.

In the presented work, the possibility of using photovoltaic silicon panels with a double-sided arrangement of solar cells on the front and back sides is presented. With a lack of space for placing solar panels, these types of modules can significantly increase the generation of electrical energy. Equipping photovoltaic systems with rechargeable batteries contributes to a more rational consumption of electrical energy, while energy storage systems significantly increase the efficiency of solar generating systems. The proposed designs are intended to increase the power characteristics of solar energy converters in the winter months, in the presence of snow or when using reflective surfaces on road surfaces. The results of the experimental studies have shown a significant efficiency of the proposed designs, as well as an increase in the total generation of electrical energy. With the development of the global technical potential and a significant increase in the production of power plants for solar energy, a new opportunity has emerged to use combined solar plants for photovoltaic conversion of the flux of incident solar radiation. At the Department of Renewable Energy Sources and Electrical Systems and Networks at Sevastopol State University, at the site of the Institute of Nuclear Energy and Industry, a photovoltaic installation was developed and studied, consisting of two side silicon solar cells and energy storage systems. The article presents the results of experimental and theoretical studies, presents diagrams, drawings and graphs of various characteristics of the FSM-110D photovoltaic panel and storage batteries. The research results show the increased efficiency of the proposed installation, as well as a good possibility of using the presented photovoltaic systems to provide them with autonomous and individual consumers living in the Crimean region and the city of Sevastopol.

The solar energy is able to supply humanity energy for almost another 1 billion years. Optical nano-antennas (ONAs) are an attractive technology for high efficiency, and low-cost solar cells. These devices can be classified to semiconductor nano-wires and metallic nano-antenna. Extensive studies have been carried out on ONAs to investigate their ability to harvest solar energy. Inspired by these studies, the scope of the chapter is to highlight the latest designs of the two main types of ONAs. The metallic nano-antennas are discussed based on the following points: plasmon, modeling, and performance of antenna designs using different configurations and materials. Moreover, the semiconductor nano-wires are studied thoroughly in terms of photonic crystals, antenna design with different patterns, nano-wire forms and materials. Also, the applications of ONAs and their fabrication aspects such as diode challenges are presented in detail. Finally, three novel designs of ONAs are presented and numerically simulated to maximize the harvesting efficiency.
