How does electrostatic separation affect waste silicon photovoltaics?

Electrostatic separation has an influence in most of the materials present in waste silicon photovoltaics. This process may assist in the recycling of waste PV.

Can electrostatic separation be used in silicon-based photovoltaic modules?

The objective of this study is to evaluate the use of electrostatic separation technique to segregate some of the main materials present in silicon-based photovoltaic modules: silver, copper, silicon, glass, and polymers from the back sheet and encapsulating material.

What is the decomposition temperature of a PV module?

The decomposition temperatures of the separated plastic materials and polymers was determined as 445.44 °C, and also heating rate and maximum temperature of 479.22 °C at which the PV module was heated in a special furnace (see Fig. 11). The PV module was placed in a vessel and heated to a temperature above 420 °C.

What is the optimal separation of silicon PV modules?

It is shown that the optimal separation is obtained under different operating voltages of 24 and 28 kV and a rotation speed of 30 RPM or higher. Furthermore, it is shown that there is no significant difference among the tested parameters. Results provide a new option in the recycling of waste of silicon PV modules that can and should be optimized.

What is the structure and material characterization of a photovoltaic module?

Structure of the photovoltaic module . 4. PV structure and material characterization The structural formation of the module is as follows (see Fig. 4): On the top of the PV module tempered glass is placed. The glass can withstand large hails and is highly shock resistant. EVA film is applied between glass and PV cells.

Can electrostatic separation assist in the recycling of waste photovoltaics?

Electrostatic separation can assist in the recycling of waste photovoltaics, but the parameters for an optimal separation are still uncertain. Zuser A, Rechberger H (2011) Considerations of resource availability in technology development strategies: the case study of photovoltaics.
