Aerogels are 3-D nanostructures of non-fluid colloidal interconnected porous networks consisting of loosely packed bonded particles that are expanded throughout its volume by gas and exhibit ultra-low density and high specific surface area. Aerogels are normally synthesized through a sol–gel method followed by a special drying technique such as

In any case, the new class of single-component devices circumvents the required electronics to connect a solar cell to a battery (such as DC–DC converters that make up a significant part of the costs of a solar power plant), although it still requires electronics to feed the energy into the grid.
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.
