The Future of Tesla

Tesla Motors isn’t your typical car company. They don’t act or produce the same way other car brands do. For starters, their initial method of selling Teslas was to open up in malls in areas such as Orange County. This unconventional approach departs from the typical car dealership experience you’d expect at other high profile car companies. This is exactly what they want: a different car buying experience

Next, Tesla doesn’t just want to sell cars. To remain competitive with other luxury brands, Tesla must stay innovative. That means expanding their market from just cars to more exotic products.

An example of this is their batteries. This unprecedented move by Elon Musk shows the direction he plans to take Tesla- to produce goods which relate to technology pertinent to cars and energy efficiency.

I’d like to make a bet. I bet the next step for Tesla is to sell organic photovoltaic paint. Of course they would use their own technology on their cars, but they will also just sell the energy efficient paint solo.

More On Organic PVs:

“A “small molecule” solar cell consists of a series of very thin vapor deposited organic layers sandwiched between two electrodes, a transparent anode (Indium Tin Oxide) and a metallic cathode on top. Two types of electrodes are used — an extremely layer of indium tin oxide (because it has to be optically transparent), is used as an anode. Low work-function metals such as magnesium, lithium, and their alloys with silver and aluminum are now used as cathodes. While there is no restriction on the size and shape of OPV devices, and every conceivable shape and form can be envisioned, only human synthetic capability is the limiting factor. The devices can be in the form of fibers, woven to fabrics, bent or rolled as films on curved surface. The near two dimensional nature of OPVs will represent a new paradigm shift and it may take some time before it is accepted by the mass market.”

And How Does This Work?

“An organic solar cell consists of a series of very thin vapor or solution deposited organic layers sandwiched between two electrodes. The basic mechanism of photocurrent generation in OPVs can be illustrated with two organic materials, one a net electron donor (D) and the other an acceptor (A).


Call out  Light Absorption

The first step of the process is light absorption, leading to exciton formation. The exciton can be formed in either the donor or acceptor layer. In order to cover a large fraction of the solar spectrum, the donor and acceptor materials chosen for OPVs have broad absorbance lines and high extinction coefficients, giving a high optical density for thin films.


Call out  Exciton Diffusion

Once formed, the exciton then migrates to the D/A interface,
or alternatively decays to the ground state. Materials and film
thicknesses are carefully selected to maximize the yield of excitons
that reach the D/A interface.


Call out  Charge Separation

At the D/A interface the exciton undergoes a charge transfer reaction, forming a hole and electron in the D and A layers, respectively. In this process an electron is transferred from the donor to the acceptor, in an exothermic process. The optimal choice of a pair of D/A materials is one which gives efficient exciton charge separation, but maintains a large energy difference between the donor hole and acceptor electron to keep a high open cell voltage.


Call out  Charge Transport & Collection

After the hole and electron are generated, they are conducted through the D and A materials and extracted by the electrodes (charge collection). Once charges reach the electrode and are extracted and transferred to the outer circuit, the electron is transferred to the cathode and the hole to the anode.”


PV paint will be a big party of the future of renewable energy. Watch as Tesla takes advantage of it.
