AI Customer ServiceAmorphous silicon (a-Si:H) solar cells, when deposited on polyimide (PI) foils, are very light (in weight). This basically opens up specific applications in aerospace technology—wherever the weight of the power supply and not its surface area counts.
Amorphous silicon (a-Si:H) solar cells have to be kept extremely thin (thickness below 0.2 μm), so as to maximize the internal electric field Eint, and, thus, allow for satisfactory collection of the photo-generated electrons and holes. Therefore, light-trapping is absolutely essential for a-Si:H cells.
Amorphous silicon (a-Si:H) thin films are currently widely used as passivation layers for crystalline silicon solar cells, leading, thus, to heterojunction cells (HJT cells), as described in Chap. 7, next-up. HJT cells work with passivated contacts on both sides.
Amorphous silicon solar cells were first introduced commercially by Sanyo in 1980 for use in solar-powered calculators, and shipments increased rapidly to 3.5 MWp by 1985 (representing about 19% of the total PV market that year). Shipments of a-Si PV modules reached ~40 MWp in 2001, but this represented only about 11% of the total PV market.
While the early deposition work was performed using primarily DC and RF PECVD , Iic-1 -Amorphous Silicon Solar Cells 283 subsequent studies showed that good quality a-Si alloys could be deposited using VHF (~30-110 MHz) and microwave (~2.45 GHz) PECVD [10, 11].
Hydrogenated amorphous silicon (a-Si:H) based thin film solar cells are designed successfully by using finite-difference time-domain method. Three optical models are developed for comparative studies to optimize the performance of the solar cell.
