How to recycle Si wafer from solar PV module?

Processes to recycle Si wafer from solar PV module The junction box, aluminium frame and cables have been separated mechanically which are attached with the help of adhesive glue (Silica gel). Mechanical separation is the only method to remove them without damage.

What is the recycling process for silicon-based PV panels?

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.).

Can silicon PV wafers be separated from glass before pyrolysis?

Some researchers have introduced a delamination method before the pyrolysis treatment, wherein silicon PV wafers are physically separated from glass (Doni and Dughiero, 2012). There is difficulty in separating glass from PV wafers due to the adhesive material between silicon solar cells and glass.

What is the module efficiency of a c-Si PV wafer?

Module efficiency values were taken from the Fraunhofer ISE Photovoltaics Report . The typical thickness of multi- and mono-Si PV wafer is 180 and 170 μm, respectively; 60 individual cells of 243 cm2 (156 mm x156 mm) are assumed to comprise a module of 1.6 m2 for all c-Si PV types.

What changes have been made to silicon PV components?

In this Review, we survey the key changes related to materials and industrial processing of silicon PV components. At the wafer level, a strong reduction in polysilicon cost and the general implementation of diamond wire sawing has reduced the cost of monocrystalline wafers.

How much electricity does a silicon wafer generate?

When the four kinds of silicon wafers were used to generate the same amount of electricity for photovoltaic modules, the ECER-135 of S-P-Si wafer, S-S-Si wafer and M-S-Si wafer were 3.3, 4.5 and 2.8 times of that of M-P-Si wafer respectively.
