The Solar Cell
Inside Our Cell
To the left is an enlarged view of SunCore’s cell top layer with SunCore’s proprietary silicon-etch process. The shapes are uniformly rectangular and of similar size as prescribed for better spectral absorption. The SEM micrograph of a competitor’s (typical) polysilicon crystal structure (on the right), illustrates that the shapes are flat, random and of varying size with voids.
Further, SunCore has a proprietary Anti-Reflective Coating (ARC) that exhibits a complex non-planar structure on the top surface of the solar cell (see left). This textured layer is comprised of small variable height and width triangular structures which trap off-axis light (high incident angle light), thereby increasing power harvesting during low angles of the sun. In effect, SunCore’s ARC ensures more PV surface area remains normal to incoming energy than a flat wafer alone. The result is a flatter, higher performance PV panel even in lower and high incident angle lighting conditions.

SunCore constructs its cell with different process elements from other cell manufacturers which results in excellent efficiency of 24% as well as lower production costs than others.
Charge Management System
The Charge Management System manages the high transfer rate of light energy from the photovoltaic array to the device lithium battery, controlling two key functions.
First, the CMS monitors the lithium battery chemistry, predetermined voltage levels and charge current transfer, improving the charge rate over traditional systems. Second, working in parallel, the CMS evaluates varying lighting conditions, making certain the greatest power level to maximize current generation is achieved.
Microcontroller, Programmable Precision
Our programmable microcontroller manages the charge process from the photovoltaic array and precisely matches it to the device’s requirements, including the lithium battery charge profiles and rates. The microcontroller also utilizes proprietary algorithms that allow battery charging in temperatures up to 65 deg. C, well beyond the standard 45 degree limit, preventing premature shut-down of charging during peak sun hours.
SunCore’s intelligent charging system maximizes current output and significantly reduces a device’s charging time. The highest device performance is a certainty assisted by our patented circuitry.
Increased Light Capture
On-Axis and Off-Axis Light | Distinctive solar cell design increases the energy gathered from reflected light, optimizes the collection of off-axis incident lighting and cuts down the effects of shadowing.
