For single-junction (n-i-p) a-Si:H thin-film solar cells, the thickness of the i-layer is a key factor in achieving a balance between photo generation and collection efficiency, consequently controlling the short-circuit current [26, 27, 30, 31, 32]. Furthermore, it’s understood that doping significantly affects device performance.
Nevertheless, several advantages of a-Si:H thin-film solar cells include relatively low fabrication cost due to processing at low temperatures and large area deposition on different substrates, including the flexible substrates, which are relatively cheaper than the silicon wafer [6, 7, 8, 9].
The most popular process used for fabricating a-Si:H thin-film solar cells on a significant scale in the industry is Plasma-Enhanced Chemical Vapor Deposition (PECVD).
After the first experimental demonstration of a-Si:H solar cell by Carlson and Wronski , hydrogenated amorphous silicon (a-Si:H) thin-film solar cells are studied extensively in the last three decades [11, 12, 13, 14] to use in multi-junction solar cells, tandem solar cells [15, 16].
To prevent the diffusion of silver in solar cells, a thin layer of AZO of 40 nm thickness was deposited over the Ag films using rf-sputtering system. After that, the n-i-p layers of a-Si:H were fabricated at 180 °C substrate temperature in different (n), (i), (p) chambers.
Moreover, doped and undoped (intrinsic) a-Si:H layers are also used in high-efficiency c-Si heterojunction (SHJ) or heterojunction with intrinsic layer (HIT) solar cells [23, 24].
