3D Coaxial Solar cell

solarex14.in : 3D Coaxial Solar cell

Requires: Device 3D/Luminous
Minimum Versions: Atlas 5.24.1.R

The solar cell is a coaxial silicon nanowire, approximately 380 nanometers thick. The nanowire consists of three layers of silicon: a positively charged core; a thin intrinsic, or neutrally charged, inner shell; and a negatively charged outer shell. When a photon hits the nanowire, it generates a pair of charges: an electron and a hole. The charges then radially move electrons outward from the center to a contact in the shell, holes move inward to a contact in the core. The advantage of the circular cross section is that the electrons and holes must move across a much shorter distance than they would in a flat cell to reach the contacts that collect them and send electricity flowing out of the device.

In Atlas3D, the CYLINDRICAL parameter enables you to create a general cylindrical structure. The MESH statement must appear as: MESH THREE.D CYLINDRICAL where the THREE.D parameter informs the simulator to create a fully 3D mesh. When specifying the CYLINDRICAL parameter, you must now specify the structure in terms of radius, angle, and cartesian Z coordinates.
