Energy materials refers to more than just solar cells that produce electricity from sunlight. Solar fuels, thermoelectric materials and topological insulators are just a few of them. These are materials that store or convert energy, or which can be used to develop new and energy-efficient information technology.
Math helps in the design of nano-antennas: Katja Höflich and her team at HZB study tiny structures made of metal shaped like corkscrews. These nano-antennas react to light and can amplify certain frequencies. (2020) (ger)
Perovskite is the new wonder material and the big hit in photovoltaic research. And because they complement silicon perfectly, perovskite and silicon can be used to develop super-efficient tandem cells. (ger)
Energy research at HZB: in an interview, scientists talk about their first encounter with the large facilities, such as the synchrotron storage ring BESSY II, and what they are planning for the future.
Hydrogen produced with light: HZB researchers have developed a new semiconducting structure, which uses sunlight to split water and produce hydrogen. See, how this structure is produced.
What does an artificial leaf do and how can you build one? How can we technically capture and store solar energy? We are investigating this at HZB and are also using our synchrotron BESSY II for this purpose. (ger)
Movements in solar cells: How does the electric charge move within a solar cell and how can the efficiency of the cells be improved?

Function of a solar cell: What are the different parts of a solar cell and how does it function?
A conventional solar cell compared with a thin-film solar cell.
The video clip shows a complex solar cell with a so-called superstrate structure. This cell works like an "artificial leaf", using sunlight to split water and produce hydrogen gas. (ger)
EMIL, the energy materials in-situ laboratory at BESSY II introduces itself and the range of research opportunities it offers.
