Liquid solar cells

Gemini AI  gives the responses. 

I really find the responses educational. I would never think to learn about norbornadiene. 

Question:  what counpounds are used in liquid solar cells?

Liquid solar cells are a relatively new technology and there are a few different compounds being researched for use in them. One promising compound is norbornadiene (C7H8).

Norbornadiene is a hydrocarbon molecule that can undergo a chemical reaction when it absorbs sunlight. This reaction causes the molecule to change shape, and in the process, it releases energy that can be converted into electricity.

Researchers are still working on improving the efficiency of liquid solar cells, but they have the potential to be a more versatile and lower-cost alternative to traditional solar panels.

Other compounds being explored for use in liquid solar cells include dyes, semiconductors, and electrolytes. Dyes are molecules that can absorb sunlight and then emit light of a different wavelength. In a liquid solar cell, a dye could be used to capture sunlight and then transfer the energy to a semiconductor material, which would then convert the energy into electricity.

Semiconductors are materials that can conduct electricity under certain conditions. In a liquid solar cell, a semiconductor material could be used to convert the energy from sunlight into electricity. Electrolytes are solutions that contain ions that can flow freely. In a liquid solar cell, an electrolyte could be used to transport ions between the electrodes, which would allow the cell to generate electricity

Question:could say ito glass and some other metalic suface with water and sodium bicaronate electrolite be use with a dye to absorb light?

The concept you describe has some similarities to a type of solar cell called a Dye-Sensitized Solar Cell (DSSC). Here's how it compares:

Similarities:

Dye: You're right, DSSCs use dyes to absorb sunlight and initiate the conversion process to electricity.

Electrolyte: Liquid electrolytes are indeed used in DSSCs, although the composition differs.

Differences:

Electrolyte: Sodium bicarbonate (NaHCO3) isn't typically used in DSSCs. Common electrolytes involve a solvent (often organic) containing dissolved salts like lithium iodide (LiI) or a redox couple like iodine (I2)/iodide (I-). These components play a crucial role in transporting ions within the cell.

Metallic Surface: While DSSCs don't directly use a metallic surface, they do utilize a semiconducting material, most commonly titanium dioxide (TiO2). This material is often deposited on a transparent conductive substrate like Fluorine-doped Tin Oxide (FTO) glass, which ITO glass essentially is.

So, can your concept work?

It's unlikely to be very efficient in its current form. Here's why:

Electrolyte: Sodium bicarbonate wouldn't provide the necessary ionic conductivity for efficient charge transport.

Metallic Surface: Metals generally don't have the desired properties for light absorption and charge separation needed in a solar cell.

What about using ITO glass with a different dye and electrolyte?

This approach is closer to a DSSC. However, DSSCs require careful optimization of all components (dye, electrolyte, semiconductor) for efficient light absorption, charge transfer, and regeneration.  Building a functional DSSC can be quite complex.
