The holes are arranged in the shape of a periodic array within the device, which ensures, according to the research team, that the cell is highly flexible, with a bending radius of 6mm. Researchers at South Korea’s Ulsan National Institute of Science and Technology (UNIST) have demonstrated a highly transparent, colorful solar cell based on silicon that they claim shows unprecedented flexibility combined with remarkable power conversion efficiency.Ĭonceived for applications in building-integrated photovoltaics (BIPV), the solar cell was designed to be built with a 100μm-thick n-Si wafer and by punching, via photolithography, micro-holes that can allow light to be transmitted through the cell itself. Color-tunable transparent silicon solar cell with 7.38% efficiency The umbrella is 8.2 feet high, has a 10.5-foot diameter, and includes panels over the entire top. The modular system means that multiple umbrellas can be strung together, leaving it up to resorts to be creative with how they integrate the technology. ![]() The project was supported by “transformable design” proponent professor Chuck Hoberman of Harvard, who worked with Italo Rota and MIT professor Carlo Ratti on the design. This provides a way to keep the beachgoer, their drinks, and Italian ice cream cool on a hot summer’s day. Solar beach umbrella design cools you… and your gelatoĪn origami-inspired umbrella that can power a refrigerator was designed by an MIT-spawned innovation firm along with architects and an Italian frozen-desserts brand. The fold-out array is meant to be deployed in the sun, shading beachgoers and generating PV energy that feeds attachable nebulizers and coolers underneath. The system includes 1,096 semi-transparent glass-glass frameless panels with 40% transparency and a power output of 54 kW. The grid-connected solar facade supplies electricity for the garage, which features approximately 300 charging boxes for electric cars. “The façade is being built with semi-transparent modules that requires a certain tilt angle and, at the same time, it is placed on a building wall that needs a high exchange of airflow between its inner and outer parts,” the company’s chief innovation officer, Anna Svensson, told pv magazine. It also claims that the air flow is beneficial for the temperature of the panels. The façade is open so the air exchange does not need to be measured, as it is far beyond the required levels for garages, according to the company. The flow of air in the garage is important because of exhaust from the vehicles. It recently installed a 646.6 kW solar façade on a newly built garage with 300 EV–charging posts in Gothenburg, Sweden, by adopting a special design it has developed for buildings with particular airflow patterns. Soltech Energy, a Swedish PV system integrator and solar product supplier, is building several PV facades in its home market. Solar on a parking structure adds a Scandinavian design flair “ Van Aubel demonstrates that solar panels, whilst collecting energy, can be beautiful and a form of art too,” Armor said in a statement, adding that the graphic design is made with a colored Moiré effect, which is an interference pattern produced by overlaying similar, but slightly offset, templates. The transparent panels produce electricity for the pavilion and simultaneously allow sunlight into its spaces and filter the light’s spectrum to enable the photosynthesis of the plants located inside the building. ![]() In this project, she used Armor’s “ASCA” organic transparent solar cells to create colored modules in which the lines and patterns are interacting with each other. ![]() Here are five of pv magazine’s favorite designs from 2021: These organic solar panels generate electricity (and maybe spread a little joy)įrance-based organic PV module maker Armor solar power films and Dutch designer Marjan van Aubel crafted transparent organic PV modules for the Netherlands’ pavilion at the Expo 2020 Dubai, the universal exposition that will take place in the United Arab Emirates in October.Van Aubel specializes in incorporating solar cells into furniture, windows, and other objects. It can also be integrated into the built environment artfully, fusing objective value with subjective enjoyment. Solar PV is being deployed rapidly on rooftops, in fields, on landfills, and other unusual places.
