How can photovoltaic solar cells be recycled?

Wei-Sheng Chen et al., reported the recycling of photovoltaic solar cells by leaching and extraction process. The silicon cell consisted of 90% of Si, 0.7% of Ag, and 9.3% of Al. 4 M nitric acid was used for the recovery of Si and 1 M hydrochloride acid was used for the recovery of Ag, Al.

How long do photovoltaic panels last?

ROSI has developed a technology to recover and recondition this silicon so that it re-enters the manufacturing process upstream. The second waste stream is at the end of the life of photovoltaic modules. Their lifespan is generally between 20 to25 years, meaning that a glut of used panels will swamp the market in the coming years.

How to deal with solar PV waste material?

Therefore, the methods of dealing with solar PV waste material, principally by recycling need to be established by 2040. By recycling solar PV panels EOL and reusing them to make new solar panels, the actual number of waste (i.e., not recycled panels) could be considerably reduced.

Should solar PV panels be recycled?

We recommend that recycling should be made commercially necessary by making manufacturers responsible for recovering materials from solar PV panels EOL. In summary, the management of panels EOL and other hazardous waste is obligatory.

Should EOL solar panels be recycled?

A comprehensive review about the importance of recycling and recovery of EoL PV panels in today’s context is presented. It is the need of the hour as several countries in the past two decades have taken up installation of solar modules as a source of clean energy and to reduce their carbon foot print.

Should PV panels be managed after the end of life?

Therefore, the management of PV panels after their end of life was not a significant concern at the early stage of development . However, as a large number of panels have reached the end of their lifespan, proper management practices are becoming a critical issue for the economy and the environment .
