Multicrystalline silicon is produced by subjecting the thin silicon film to temperatures between 400 and 600 ºC. This annealing process enhances the device power conversion efficiency by 8% and increases the production yields to more than 90%. Crystalline silicon on glass (CSG), where multi-crystalline silicon grows to 1–2 µm is known for its

The next generation of lithium ion batteries (LIBs) with increased energy density for large-scale applications, such as electric mobility, and also for small electronic devices, such as microbatteries and on-chip batteries, requires advanced electrode active materials with enhanced specific and volumetric capacities.

However, Tammaro et al. (Tammaro et al., 2016) observed that some silicon amorphous (a-Si) thin film panels showed high levels of Al, Pb, and Cr in their leachates and induced partial ecotoxicity to algae (P. subcapitata), water fleas (D. magna), and bacteria (V. fisheri).
The manufacture of amorphous silicon photovoltaic cells is based on plasma-enhanced chemical vapor deposition (PECVD), which can be used to produce silicon thin film. Substrate can be made of the flexible and inexpensive material in larger sizes, for example stainless steel or plastic materials. The process is the roll-to-roll method.
The efficiency of amorphous silicon solar cells has a theoretical limit of about 15% and realized efficiencies are now up around 6 or 7%. If efficiencies of 10% can be reached on large area thin film amorphous silicon cells on inexpensive substrates, then this would be the best approach to produce low cost electricity.

The main disadvantage of amorphous silicon solar cells is the degradation of the output power over a time (15% to 35%) to a minimum level, after that, they become stable with light . Therefore, to reduce light-induced degradation, multijunction a-Si solar cells are developed with improved conversion efficiency.
