Electronic applications involving the production and transmission of energy are of fundamental importance today. The search for sustainable solutions is increasingly, along with the need to contain carbon dioxide emissions by reducing the greenhouse effect, favoring the use of renewable energy sources. The ability to produce energy from alternative sources such as the sun, wind, wave action and biomass allows for a significant reduction in environmental impact and polluting emissions compared to traditional fossil fuel-based energy sources. Solar energy, for example, can help developing countries or small, rural mountain communities to equip themselves with efficient, economical and virtually environmentally free plants for the production of electricity. Photovoltaic (PV) panels have experienced rapid and significant development in recent years, offering users increasingly efficient and reliable solutions that require less maintenance and are capable of producing energy even in low solar radiation conditions. At the same time, the simplicity of installation has grown, thanks to the introduction of flexible panels capable of adapting to surfaces of various types. PV systems are usually combined with special units to store the electricity produced, made from more or less advanced storage batteries depending on the available budget. These batteries collect energy during the day and then make it available to light and run various loads during the night. Not only that, but they can detect a power outage, automatically becoming the primary power source in the event of a power outage. Unlike generators, storage batteries can provide power without using fuel and in a silent way. The transmission of power is of equal importance in power production, especially if it can happen wirelessly, without the need for bulky and often annoying electrical cables. Wireless electricity transmission technology, based on the principle of electromagnetic induction, has come back to the fore recently thanks to two applications that have become priority. The first, related to the consumer electronics sector, relates to charging portable devices powered by batteries (usually smartphones), which can be recharged simply by placing them on a suitable source capable of transmitting electricity by conduction. The second major application relates to recharging batteries in hybrid electric and electric vehicle vehicles, which is implemented by devices that can be placed on the ground under the vehicle or even integrated into the road surface. In addition to not requiring the connection of electrical cables, this solution proves to be very effective from a safety point of view, as it does not expose the user to the potential risks of contact with the higher powers involved. In this article, two very innovative applications will be presented, related to the exploitation of solar energy as a source of electricity and wireless power transmission in different types of contexts. Flexible Roll Solar PV, based in Sunderland (UK), has developed an innovative model of solar film capable of generating and storing energy. Lightweight and flexible, the solar film can adapt to any type of surface, and produce electricity at a cost of up to 20X less than traditional PV panels. The new technology is based on a flexible film embossed with thousands of fine edges. Each micro-slit is a few microns thick, which is smaller than a human hair. The advantages offered by this solution are: Low cost: $0.03/watt for final product Low weight: 0.3kg/m2 Easy installation and reduced maintenance times Sustainability, due to use of fully recyclable materials and no rare earths Adaptability: Same technology can be used Either on rooftops or to operate small IoT sensors. High energy density: 500 W/kg As shown in Figure 1, flexible film enables mass fabrication of capacitors using a range of insulators and storage materials. Capacitor technology, used for energy storage, provides: Extremely low cost manufacturing Exceptional energy density Multiple shapes and sizes with voltage and capacitance flexibility Improved operating life compared to wet electrolytic capacitors. 1. Figure 1: Flexible Solar PV Panel Fabrication Steps “Our technology has many advantages over flexible solar technology,” said Neil Spahn, Managing Director of Power Roll. “It is very easy to produce. There are fewer steps in the manufacturing process. If you look at flexible photovoltaic cells, we can say that they are much more expensive. So actually, the main advantage of our technology is cost-effectiveness. In terms of efficiency, our efficiency is good. But we are not aiming to Making the world’s best performing solar panels.There are some technologies that are pushing the hardware higher.We are looking for a compromise,good level of performance.So our current cells performance is 11%,which is somehow comparable to other flexible solar panels like photovoltaic Membership but we plan to increase it up to 20%. Thanks to the possibility of customization, there is a wide range of applications.” Please visit the eBook for the full article.
