This has been documented as a 20% increase in voltage, which increases the total amount of watts produced by the solar cell by 20% (Watts = Voltage X Amperage). So if a solar cell is rated at 20% efficiency for flat panels, in the Spin Cell, that same solar cell will increase to 24% efficiency, by design.
The surface of a solar cell looks and feels flat, but it is Mount Everest meets the Mariana Trench at the micro level. " The deep crevasses create myriad surfaces for light, which enters at divergent angles through the optics on the outer cone to excitate more electrons. The bands of light created by the optical lensing of the Spin Cell do not focus the light at a single angle. Instead, the lenses vary the light in multiple angles to take full advantage of the varied surface of the PV cell.
One of the big challenges people have in understanding the Spin Cell breakthrough is trying to apply a flat, static paradigm over a dynamic spinning model. The classic is that there are only 1000 watts of light in a square meter. Yes...if you are looking at a flat surface. But when you calculate in the 3D aspect of PV, you can have four or five times more surface area to capture light -- if the light is coming from myriad angles.
A coastline, for example, might only be one mile as the crow flies, but it might have five miles of beaches. The problem has been that static flat panels only receive the light from one angle, which has limited PV's potential (yes, the sun will hit the panel from multiple angles as it moves across the sky, but this pace does not take advantage of PV's ability to respond in nanoseconds). The Spin Cell is specifically designed to capture the flashing light from myriad angles that flat panels have been missing.
This confusion goes so deep that some PV experts have stated that if dynamic spin had any value, it would have showed up during the standard flash testing of PV. But that light is still coming from a single angle during those tests. The advantages of dynamic spin have never been tested or documented until now.
Because light hits the 3D surface of the Spin Cell PV from multiple angles through the lensing and the spinning of solar cells on a conical axis, the Absorption Coefficient and the Absorption Depth of Silicon are both increased, thus improving the efficiency of the PV and lowering the levelized cost of energy.
The type of lensing used on the outer cone of the Spin Cell increases the photon flux on the inner cone covered with PV. This is significant because the lensing material costs 92% less than the PV material. With the Spin Cell and the lensing, we can produce the same amount of power using 95% less PV material, thus significantly reducing the cost/watt ratio.
The conical design of the Spin Cell creates significantly greater internal volume, which results in a much higher optical path length -- providing the ideal environment to manipulate the light for maximum wattage production.
PV Cells are fundamentally photodiode semiconductors. The band gap of a semiconductor is the minimum energy required to excite an electron that remains in its bound state into a free state where it can participate in conduction. The band structure of a semiconductor gives the energy of the electrons on the y-axis and is called a "band diagram". The lower energy level of a semiconductor is called the "valence band" (EV) and the energy level at which an electron can be considered free is called the "conduction band" (EC).
The band gap (EG) is the gap in energy between the bound state and the free state, between the valence band and conduction band. Therefore, the band gap is the minimum change in energy required to excite the electron so that it can participate in conduction. Flat panels with a one-sun configuration are inefficient in excitating electrons across the band gap. The Spin Cell increases the efficiency of absorption of light energy onto the PV surface, more electrons are excitated for high power generation. The power electronics discreetly manages that conduction to produce maximum wattage.
