Amorphous silicon (a-Si:H) solar cells have to be kept extremely thin (thickness below 0.2 μm), so as to maximize the internal electric field Eint, and, thus, allow for satisfactory collection of the photo-generated electrons and holes. Therefore, light-trapping is absolutely essential for a-Si:H cells.
In this review article, the complete recycling process is systematically summarized into two main sections: disassembly and delamination treatment for silicon-based PV panels, involving physical, thermal, and chemical treatment, and the retrieval of valuable metals (silicon, silver, copper, tin, etc.).
The pyrolysis thermal treatment process effectively removes adhesive material and all other materials from the PV panel (Dias et al., 2016). Bohland and Anisimov, 1997 proposed a pyrolysis method to recycle solar PV panels in an inert environment, allowing the recovery of glass, silver, and lead without disposing of them in water.
Amorphous silicon (a-Si:H) solar cells, when deposited on polyimide (PI) foils, are very light (in weight). This basically opens up specific applications in aerospace technology—wherever the weight of the power supply and not its surface area counts.
Most of the important differences in the physics of a-Si based solar cells and crystalline silicon solar cells are a direct result of the most fundamental difference in the materials -the large density of localised gap states in a-Si:H.
Shin et al. (2017) recovered silicon from EOL solar panels and fabricated lead-free silicon solar panels in three steps. In the first step, nitric acid (HNO 3) and potassium hydroxide (KOH) were used to dissolve silver and aluminium, respectively.
Amorphous vs Monocrystalline Solar Panels
Cost. While both types of solar panels have seen significant cost reductions in recent years, there is still a noticeable difference in their pricing. Amorphous silicon panels generally have a lower upfront cost compared to monocrystalline panels.. This cost advantage can be attributed to the simpler manufacturing process involved in producing amorphous …
