| 摘要 |
The present disclosure presents a three-dimensional thin film solar cell (3-D TFSC) substrate having enhanced mechanical strength, light trapping, and metal modulation coverage properties. The substrate includes a plurality of unit cells, which may or may not be different. Unit cells are defined as a small self-contained geometrical pattern which may be repeated. Each unit cell structure includes a wall enclosing a trench. Further, the unit cell includes an aperture having an aperture diameter. For the purposes of the present disclosure, the dimensions of interest include wall thickness, wall height, and aperture diameter. A pre-determined variation in these dimensions among unit cells across the substrate produces specific advantages.
