Conversion of efficiencies is given in gray. The charging state of the solar battery can be described by the amount of charges C [C g –1] stored on the device, the energy E [Ws g –1] of the accumulated charges, and a cell voltage U [V] that develops from the energy difference between the potential of the anode and cathode.
By performing both light absorption and charge storage, bifunctional materials enable the most recent and highest level of material integration in solar batteries. To conclude, bifunctional materials are the most recent development in solar battery research.
Since in a GCD experiment the applied current is constant, the required voltage is proportional to the required charging power. Not only the electrochemical signature but also the operation modes of a solar battery depend on whether it is derived from IEC or VEC architectures.
(75) During operation of the solar battery, the charging state descriptors C, E, and U are modified by different inbound or outbound energy fluxes (Figure 5 a, middle): (i) Photocharging occurs upon light absorption and separation of the electron hole pair. Both charge carriers then are available for charging the battery.
Solar batteries present an emerging class of devices which enable simultaneous energy conversion and energy storage in one single device. This high level of integration enables new energy storage concepts ranging from short-term solar energy buffers to light-enhanced batteries, thus opening up exciting vistas for decentralized energy storage.
Since no external wires are required for photocharging and a BAM is employed, this solar battery design represents a very high level of integration. By performing both light absorption and charge storage, bifunctional materials enable the most recent and highest level of material integration in solar batteries.
