... this integrated solution is not just cheaper but efficient too. It has been observed by the researchers that, these solar batteries are 25% cheaper and 20% more efficient as compared to the traditional batteries.
... In fact, the researchers told that, there are 2 very discrete chemical reactions which happen inside the solar battery. At the time of discharging of the battery, the lithium reacts with the oxygen in order to make lithium peroxide (Li2O2) and electricity, and as a result it breathes in. Alternatively, when the solar battery recharges, the solar cell makes electrons (via the photovoltaic effect) that change the lithium peroxide molecules back into lithium ions (Li+) and oxygen (O2) and eventually the battery breathes call off. There’s an iodide “shuttle” in the electrolyte, which actually helps in carrying electrons between the electrodes. The solar cell itself is quite simple and cheap dye-sensitized titanium dioxide panel, with iron oxide (rust) as the dye. Dye-sensitized solar cells (DSSCs) aren’t quite as efficient as silicon. They crest out at around 15% at the moment, though they make up for it by being cheaper and jagged.
