Printing solar cells and batteries on paper :

.

Over the past ten years, paper has emerged as a focus area for researchers developing innovative techniques for printed basic electronics components. The goal of this research is to replace plastic substrates with low-cost, versatile and sustainable materials.

The main advantages of investing in paper for electronics and energy storage devices are as follows: 1) the low cost of the technology; 2) the potentiality to recover device components and recycle the substrate as well as the active materials; and the production of 3) environmentally harmless and 4) biocompatible devices.

Already, as we have reported in numerous previous Nanowerk Spotlights, electronic paper displays are a commercial reality and prototypes of things like paper batteries, solar cells, nanopaper transistors, thermoelectric nanogenerators, graphene-enabled optoelectronics, biosensors, and even microfluidic lab-on-chip devices are under development.

In these applications, paper can be used simply as the flexible substrate onto which researchers transfer thin-films, nanoparticles or other nanostructures via various processes such as printing. Alternatively, by exploiting its porous fiber-like nature, paper can be used as an active film by infiltration or copreparation with electronic materials to give additional functionalities to the cellulosic paper.
