Francesco Bonaccorso gained a PhD from the Department of Physics, University of Messina in Italy after working at the Italian National Research Council, the Engineering Department of Cambridge University (UK) and the Department of Physics and Astronomy of Vanderbilt University (USA). In June 2009 he was awarded a Royal Society Newton International Fellowship at the Engineering Department of Cambridge University, and elected to a Research Fellowship at Hughes Hall, Cambridge. He is currently Researcher at the Istituto Italiano di Tecnologia, Graphene Labs. He was responsible in defining the ten years scientific and technological roadmap the for the graphene flagship programme. His research interests encompass solution processing of carbon nanomaterials (such as graphene, nanotubes and nanodiamonds) and inorganic layered materials, their spectroscopic characterization, incorporation into polymer composites and application in solar cells, light emitting devices, lithium-ion batteries and ultrafast lasers.

Abstract
Technological progress is driven by developments in material science. Breakthroughs can happen when a new type of material or new combinations of known materials with different dimensionality and functionality are created. Graphene, because of its many superior materials properties, has the opportunity to enable new products.1 Graphene is just the first of a new class of two dimensional (2d) crystals, derived from layered bulk crystals.2 The assembly of such 2d crystals (heterostructures) will provide a rich toolset for the creation of new, customised materials.
New materials and processes1 can improve the performance of existing devices or enable new ones that are also environmentally benign. In this context, graphene and other 2d crystals are emerging as promising materials.1-5 A key requirement for applications such as flexible electronics and energy storage and conversion is the development of industrial-scale, reliable, inexpensive production processes,2 while providing a balance between ease of fabrication and final material quality with on-demand properties.
Solution-processing offers a simple and cost-effective pathway to fabricate various 2d crystal-based photovoltaic devices, presenting huge integration flexibility compared to conventional methods. Here I will present an overview of graphene and other 2d crystals for flexible and printed photovoltaic, starting from solution processing of the raw bulk materials,2 the fabrication of large area electrodes3 and their integration in the final devices.
