6 FAQs about [Grating Solar Cells]
What are grating solar cells?
One category of these alternative devices may be generally classified as "grating" solar cells. While the conventional diffused p-n junction device itself requires a grating structure as an electrode to the heavily doped surface region, this grating is on a considerably coarser scale than those employed in the cells described here.
Are tapered gratings a good design concept for ultra-thin solar cells?
Tapered gratings have higher light absorption and lower structure sensitivity. In this paper, the cylindrical, conical and parabolic nanostructures inherited from self-organized anodic aluminum oxide (AAO) are applied to silicon-based ultra-thin solar cells aiming for a new design concept for low-cost, high-efficiency double-grating solar cells.
Are nanostructured gratings a good choice for ultra-thin solar cells?
Further results show that the conical and parabolic nanostructured gratings have higher light absorption efficiency and lower structure morphology-dependent sensitivity than the cylindrical nanostructured one, which is more conducive to the application of high efficiency ultra-thin solar cells.
How do I create a solar cell based on a grating?
Open the solar_grating.ldev file. Under the CHARGE solver in the objects tree, right click on Gen_s, open the edit window, and then using the browse button, import the Gen_s.mat file. Click LOAD and OK. Repeat the same procedure for the Gen_p object and import the Gen_p.mat file. The solar cell has been fully modeled in the CHARGE simulation.
Do grating solar cells have dark currents?
We may further subdivide grating solar cells into two groups, depending on whether the dark currents in these devices are predominantly due to ma- jority or minority carriers in the silicon; we refer to these as majority and 0379-6787/83/$3.00 Elsevier Sequoia/Printed in The Netherlands 338 minority carrier grating solar cells.
Which grating is best for ultra-thin solar cell?
Numerical results reveal that the optimal bottom metal grating can enhance the absorption capacity of ultra-thin solar cell at 0.5 µm–1.1 µm waveband with a very small parasitic absorption. Meanwhile the surface grating with a period of 0.1 µm can strongly enhance the absorption of solar cell in 0.3 µm–0.5 µm waveband.
