SUMMARY:Light-rechargeable Batteries: A New tool to Fight Climate Change?

DESCRIPTION:This talk will introduce a new type of battery electrode that 
 can be recharged directly by light\, without the need for external solar c
 ells or external power supplies. These devices may change the way we power
  off-grid devices and provide a tool to fight energy poverty in developing
  communities. However\, this is an emerging technology that still suffers 
 from tremendous challenges that need to be solved before we can dream of c
 ommercialising it. In this talk\, I will first discuss the operating princ
 iples of light-rechargeable batteries and in particular how they are able 
 to harvest solar energy and store it. Then I will discuss challenges relat
 ed to the stability of these devices and their light conversion efficiency
 . Finally\, I will give an outlook of the challenges related to the scale-
 up manufacturing and commercialisation of these systems as well as the rol
 e they might play on the long term in fighting energy poverty and climate 
 change.
