Is it a solar cell, a battery? No, it’s a solar battery!

Is it a solar cell or a rechargeable lithium-air battery? No…Actually it’s both! Though it seems quite shocking, but it’s true. It’s the worlds all in one solar battery.

Well, this exciting device is formed by Ohio State University. It is basically an air-breathing battery, which has built in solar cell for recharging. No doubt, this is actually a momentous discovery so far, because one of the major problems with the solar systems is that they need big batteries in order to stock up electricity. Also, these batteries are quite expensive and the other thing is, lots of electricity is lost during the traveling from one solar panels to external storage. On the other hand, 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.

Moreover, this novel solar battery comes with a nifty design. This solar battery has 3 electrodes. One is standard lithium metal anode, second is an oxygen/air electrode in the middle, and the third one is a photo-electrode (photovoltaic solar cell) fitted on the top. Furthermore, the electrolyte sandwich guarantees that electrons can move slickly between each electrode. At the time of charging, the solar cell is connected to the lithium electrode, and on discharging, the lithium electrode is connected to the oxygen.

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.

This solar battery is developed by Yiying Wu along with his friends at Ohio State University. The design of the battery is original. Moreover, Wu stated that, the design will be certified to industrial partners, which would help in order to overthrow the cost of solar power.

Scientists Create World’s First Automatic Rechargeable Solar Battery

Ohio State University scientists invented the world’s first rechargeable battery with its own solar cell solar battery, which is the newest improvement in the world of transferable power supplies, the scientists have succeeded in combining a battery and a solar cell into one hybrid apparatus, which could be massive in terms of renewable energy capture and storage.

This latest solar battery could create it more reasonable for homeowners and businesses to use solar energy fairly than less sustainable sources of power. Yiying Wu, a professor at Ohio State and one of the inventors of the solar battery, said that the gadget could cut down costs by 25 percent and if solar power becomes less costly to execute, this could make a lot of inroads for more extensive use of renewable energy.

The major factor of the latest device is a mesh solar panel, which permits air to come into the battery and there’s also a unique method for transferring electrons between the solar panel and the battery electrode; within the device, light and oxygen allow different parts of the chemical reactions that charge the battery.

The brilliant inventor said that fundamentally, it’s a breathing battery, it breathes in the air when it discharges, and breathes out when it charges.

The inventor further said that the mesh solar panel forms the initial electrode and under the mesh is a slim sheet of porous carbon, which works as the second electrode, and a lithium plate, which works as the third electrode. Between the electrodes are sheets of electrolyte to hold electrons back and forth and during charging, light strikes the mesh solar panel and generates electrons.

Then, within the battery, electrons are engaged in the chemical breakdown of lithium peroxide into lithium ions and oxygen and finally the oxygen is released into the air, and the lithium ions are accumulated in the battery as lithium metal after capturing the electrons.

The discoveries could be massive in terms of creating long-lasting energy for powering a mixture of devices that’s why the researchers are continuing to move forward in improving the effectiveness of the battery and the amount of power the panel can absorb and transferred.
