Radiation Effects and Annealing Studies on Amorphous Silicon Solar Cells
Results of radiation effects and annealing studies are presented for amorphous silicon solar cells from three manufacturers. Data scale well with ionizing dose in many cases for proton, x-ray, and electron irradiation. Significant long-term annealing occurs at room temperature. Results for small-area diodes are in reasonable agreement …
Ultrathin amorphous silicon thin-film solar cells by magnetic …
Efficient solar harvesting for ultrathin amorphous silicon (α-Si) films with a thickness of less than 100 nm is critical to the performance of solar cells, since the very short carrier-diffusion length of α-Si and the Staebler–Wronski effect restrict their thickness. In this work, we numerically investigate
Amorphous Silicon
3.1 Amorphous Silicon. Amorphous silicon solar cells are commercially available and can be produced on a variety of substrates ranging from glass to flexible thin foils. Cells are built in p-i-n or n-i-p configurations, where p and n represent thin doped (amorphous or nanocrystalline) layers, and the absorber layer is an intrinsic undoped layer.
Amorphous silicon solar cells | IEEE Journals & Magazine
Amorphous silicon solar cells have been fabricated in several different structures: heterojunctions, p-i-n junctions, and Schottky barrier devices. The procedures used in constructing the various solar cells are discussed, and their photovoltaic properties are compared. At present, the highest conversion efficiency (5.5 percent) has been …

Comprehensive Study of Different PECVD-Deposition Methods for ...
This work tackles the question whether a soft PECVD-deposition of intrinsic, hydrogenised, amorphous silicon (a-Si:H(i)) is really supportive for the passivation quality of the heterojunction interface between a crystalline wafer and the a-Si:H(i)-layer itself. Two PECVD-deposition methods are under investigation: i) parallel plate 13.5 MHz …
Amorphous Silicon Solar Cells
Amorphous silicon solar cells are different from other types of solar cells, such as crystalline silicon solar cells or thin-film solar cells, in several ways. One of the main differences is their flexibility and lightweight design, which allows them to be used in a wider range of applications. Additionally, amorphous silicon solar cells are ...
