Storable sunshine , reusable rays : A solar rechargeable redox flow battery is proposed based on the photoregeneration of I3 ( - ) / I ( - ) and [ Fe ( C10 H15 ) 2 ] ( + ) / Fe ( C10 H15 ) 2 soluble redox couples , which can be regenerated by flowing from a discharged redox flow battery ( RFB ) into a dye - sensitized solar cell ( DSSC ) and then stored in tanks for subsequent RFB applications This technology enables effective solar - to - chemical energy conversion .
 Chemical: I3 ( - ); Chemical: I ( - ); Chemical: [ Fe ( C10 H15 ) 2 ] ( + ); Chemical: Fe ( C10 H15 ) 2
