	abstract = {<p>A novel generation of flexible opto-electronic smart applications is now emerging{,} incorporating photovoltaic and sensing devices driven by the desire to extend and integrate such technologies into a broad range of low cost and disposable consumer products of our everyday life and as a tool to bring together the digital and physical worlds. Several flexible polymeric materials are now under investigation to be used as mechanical supports for such applications. Among them{,} cellulose{,} the most abundant organic polymer on the Earth{,} commonly used in the form of paper{,} has attracted much research interest due to the advantages of being recyclable{,} flexible{,} lightweight{,} biocompatible and extremely low-cost{,} when compared to other materials. Cellulose substrates can be found in many forms{,} from the traditional micro-cellulose paper used for writing{,} printing and food/beverage packaging (e.g. liquid packaging cardboard){,} to the nano-cellulose paper which has distinct structural{,} optical{,} thermal and mechanical properties that can be tailored to its end use. The present article reviews the state-of-the-art related to the integration and optimization of photonic structures and light harvesting technologies on paper-based platforms{,} for applications such as Surface Enhanced Raman Scattering (SERS){,} supporting remarkable 107 signal enhancement{,} and photovoltaic solar cells reaching [similar]5\% efficiency{,} for power supply in standalone applications. Such paper-supported technologies are now possible due to innovative coatings that functionalize the paper surfaces{,} together with advanced light management solutions (e.g. wave-optical light trapping structures and NIR-to-visible up-converters). These breakthroughs open the way for an innovative class of disposable opto-electronic products that can find widespread use and bring important added value to existing commercial products. By making these devices ubiquitous{,} flexible and conformable to any object or surface{,} will also allow them to become part of the core of the Internet of Things (IoT) revolution{,} which demands systems{{\textquoteright}} mobility and self-powering functionalities to satisfy the requirements of comfort and healthcare of the users.</p>
