Amorphous silicon (a-Si) is a non-crystalline form of silicon that is used in solar cells and thin-film transistors in liquid crystal displays. It is deposited in thin films onto a variety of flexible substrates, such as glass, metal, and plastic, as a semiconductor material for a-Si solar cells, or thin-film silicon solar cells. Amorphous silicon cells are notoriously inefficient.
As a second-generation thin-film solar cell technology, amorphous silicon was once expected to be a major contributor to the rapidly growing global photovoltaic market, but it has since faded due to strong competition from conventional crystalline silicon cells and other thin-film technologies such as CdTe and CIGS. Amorphous silicon is a preferred material for liquid crystal display (LCD) thin film transistor (TFT) elements and x-ray tubes.
The most advanced thin-film solar cells are amorphous silicon solar cells. The structure is typically p-i-n (or n-i-p), with p-layer and n-layer primarily used for establishing an internal electric field (i-layer) composed of amorphous silicon.
The majority of pocket calculators are powered by amorphous silicon thin film solar cells. Amorphous silicon solar cells’ low power output limited their use to small applications for a long time.
The Global Amorphous Silicon Solar Cells market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
At least seven companies, including ARCO Solar, Chronar, Energy Conversion Devices, Glasstech Solar, Solarex, Utility Power Group, and Iowa Thin Technologies, are actively involved in bringing a-Si technology from the lab to the market.
The “Staebler-Wronski” effect, which causes a reduction in a-Si device efficiency when exposed to light, is one of the key issues in this technology. Two approaches are being pursued to reduce the effects of light.
Solarex has achieved the highest single-junction module efficiency for a-Si to date, with a power output of 9.18 W and an aperture area of 933 cm2.
