«Benefitting from the ethyl acetate - based electrolyte and
organic polymers electrodes, the rechargeable battery can work well at the ultra-low temperature of -70 degrees Celsius,» Xia says.
In a semi-transparent solar cell module as shown in the photograph,
electrodes with two variants of the
polymer PEDOT: PSS (commonly used in
organic electronics) are used, where one acts as the anode and the other is modified to become the cathode.
