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. This apparent

At its core, the amorphous silicon solar cell structure comprises of a thin layer of non-crystalline silicon. This thin film is typically deposited onto a substrate, creating a flexible and lightweight structure. The absence of a crystal lattice in amorphous silicon allows for a more straightforward manufacturing process and reduces material waste.
One of the advantages of amorphous silicon–based solar cells is that they absorb sunlight very efficiently: the total thickness of the absorbing layers in amorphous silicon solar cells is less than 1 μm. Consequently, these layers need to be supported on a much thicker substrate.
In crystalline solar cells, the orderly arrangement of atoms in the crystal lattice can result in some photons having insufficient energy to dislodge electrons. In contrast, the disordered, non-crystalline structure of amorphous silicon allows for a broader range of photon energies to be absorbed.
The absence of a crystal lattice in amorphous silicon allows for a more straightforward manufacturing process and reduces material waste. The working principle of amorphous silicon solar cells is rooted in the photovoltaic effect. Here is a complete structure of the mechanism of the cells.
In amorphous silicon solar cells, the top, the heavily doped layer is thin and practically transparent, allowing incident light to flow through and generate free photogenerated electrons and holes in the undoped layer.
