In the race for ever higher efficiency levels, an Helmholtz Zentrum Berlin (HZB) development team has once again pulled ahead. The groups of Steve Albrecht and Bernd Stannowski have developed a tandem solar cell made of the semiconductors perovskite and silicon that converts 29.15 per cent of the incident light into electrical energy. This value has been officially certified by the CalLab of the Fraunhofer Institute for Solar Energy Systems (ISE) and means that surpassing the 30 per cent efficiency mark is now within reach.
Climate change is happening right now with proven negative impact on our environment, economies and societies. The key to slow down the global warming process is the significant reduction of greenhouse gases at all stages of industrial processes. Therefore, a massive turnaround of energy production towards low carbon technologies is essential. Heliatek (Dresden, Germany) brings an innovative organic solar film solution (HeliaSol) as a powerful means for the decarbonisation of the energy sector. HeliaSol is an ultra-thin, lightweight, flexible all-in-one solution that can add value to virtually any building surface — from glass, metal and concrete to polymer membranes — turning it into clean electricity generators, no matter if they are flat, curved or even semi-permanent.
At the European Photovoltaic Solar Energy Conference (EU PVSEC) in Marseille (France), Imec (Leuven, Belgium), a world-leading research and innovation hub in nanoelectronics, energy and digital technologies and EnergyVille, together with PVcase, a Lithuanian software company disrupting the way solar parks are engineered globally, presented their partnership to develop a commercial software solution that allows to easily design and accurately predict the energy yield of state-of-the-art photovoltaic (PV) power plants. First blind tests of the prototype software already show best-in-class results for bifacial PV plants and the go to market is targeted for the first half of 2020.
