AI Customer ServiceThis light-scattering effect is a key characteristic of high-efficiency thin-film silicon solar cells. Additionally, surface scattering is of great significance for thin-film silicon solar cells.
Compared with conventional silicon nanowires, which were only covered with SiN x, the open circuit voltage Voc and short circuit current Isc of double-passivation silicon nanowire-texture solar cells increased by 2% and 10%, respectively. The effective carrier lifetime increased by 28% . Table 2.
At the same time, the volume of silicon wafer is reduced, and the thickness of thin-film silicon solar cell is reduced, which is more conducive to the transport of photogenerated carriers; therefore, it not only reduces the cost of raw materials but also improves the carrier collection efficiency.
As a result of the indirect optical transition in crystalline silicon, light absorption in the film is very low. To absorb most of the solar spectrum in the film with a thickness of only several microns, light absorption must be increased. Therefore, a complex optical capture scheme is proposed.
Poruba et al. analyzed the surface- and bulk-scattering effects of microcrystalline silicon thin-film solar cells, which were deposited by very high-frequency glow discharge (VHF-GD). This was done using the constant photocurrent method (CPM).
Then, it is reflected into the silicon layer via an aluminum back reflector, thus increasing the optical path of the incident light in the silicon layer . For commercial solar cells, the most common surface texture is the pyramid structure. The light-trapping mechanism for pyramid textures larger than several microns is shown in Figure 1 (b).
