DSSCs go green: The front cover artwork was chosen to show that an innovative biocomposite polymer electrolyte, obtained by incorporation of truly natural, renewable, and recyclable nanoscale, microfibrillated cellulose into a photo-curable methacrylicbased polymeric network, can be obtained and used in quasi-solid state dye sensitized solar cells. By the cumulative effect of the strategic components employed and the fine tuning of the experimental conditions, C. Gerbaldi et al. are able to achieve remarkable efficiencies up to 7.0 % under 1 sun irradiation (8.25 % under 0.4 sun).
