Experimental validation of crystalline silicon solar cells recycling by thermal and chemical methods Sol. Energy Mater. Sol. Cell., 94 ( 2010), pp. 2275 - 2282, 10.1016/j.solmat.2010.07.025 Re-cycling of high value, high energy content components of silicon PV modules

Which materials are used in c-Si solar cells?

The highest efficiencies of c-Si solar cells to date are reported using charge-selective contacts that are made of Si-based materials such as amorphous silicon (a-Si) forming the silicon heterojunction (SHJ) solar cells or silicon oxide (SiO x ) stacked with heavily doped polycrystalline silicon (SiO x /poly-Si) [1, 5].

How can the recovery and concentration of solar cells be improved?

And the recovery and concentration of the solar cells can be further improved by optimizing. Firstly, the narrow-grade classification is an important method in improving the recovery and concentration of solar cells. It can be achieved by customizing special mesh sizes.

How can crystalline silicon (c-Si) solar cells improve conversion efficiency?

To further increase the conversion efficiency of crystalline silicon (c-Si) solar cells, it is vital to reduce the recombination losses associated with the contacts.

What is a passivating contact for a solar cell?

Although the passivation quality pro vided temperatures such as 200 °C , . Especially in the case bond breakage . Therefore, subsequent solar cell manufac- ( >700 °C) typically employed in other solar cell concepts. Another Si-based contact is the SiO x/poly-Si structure. This passivating contact for c-Si solar cells.

How can crystalline silicon (c-Si) photovoltaic (PV) modules be recycled?

Reasonable and efficient recycling of waste crystalline silicon (c-Si) photovoltaic (PV) modules benefits environmental protection and resource conservation. The liberation and separation of solar cells in modules is the key to achieving effective recycling.
