In the years hybrid and organic solar cells have advanced enormously in terms of efficiency, lifetime, and technology and have a true promise to become an important source of renewable energy. In addition, they present fascinating opportunities and challenges for scientific research and technological development. The main topics of this conference are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells that makes a major contribution to the conference, but other hybrid technologies, as ,organic solar cells, quantum dot solar cells, and dye-sensitized solar cells, continue to be popular, as well as their integration into devices for photoelectrochemical solar fuel production. Building upon success of the previous edition, and on a well established reputation, the HOPV conferences provide an excellent opportunity for scientists and engineers around the world to discuss the latest developments in hybrid and organic photovoltaics. The conference are led by world leading invited speakers covering a broad range of the latest scientific advances in morning plenary sessions. The conference encourages presentation of oral as well as poster contributions from scientists from all over the world, in four parallel sessions running in the afternoons. Just submit your abstracts before the deadline, which is strict. Special attention is given to the poster contributions.
