Solar Cells: Conversion of Solar Energy into Electrical Energy Storage: Supercapacitor as an Ultrafast Energy‐Storage Device Made from Biodegradable Agar‐Agar as a Novel and Low‐Cost Carbon Precursor (Global Challenges 10/2018)

To reduce environmental pollution and the cost of electricity production, renewable energy conversion and storage is an alternative solution to overcome the energy shortage and minimize the problem of dispatching electricity on demand. Solar supercapacitors can be considered as ultrafast next‐generation energy storage devices that can mitigate the energy demand and reduce electricity costs. Further details can be found in article number 1800037 by Mani Karthik and co‐workers. [Image: see text]
