Harm of photovoltaic panel silicon wafers
The International Renewable Energy Agency (IRENA) estimated that at the end of 2016, there were around 250,000 metric tonnes of solar panel waste globally [12]. The solar panels contain lead (Pb), cadmium (Cd) and many other harmful chemicals that could not be removed if the entire panel is cracked [[17], [18], [19]].

Mass installation of silicon-based photovoltaic (PV) panels exhibited a socioenvironmental threat to the biosphere, i.e., the electronic waste (e-waste) from PV panels that is projected to reach 78 million tonnes by the year 2050.
Recycling of PV panel is currently not economically viable because waste volumes generated are too small; significant volumes of end-of-life photovoltaic panels will begin to appear in 2025 or 2030. An overview of social and environmental impacts of PV technologies is presented in this paper along with potential benefits and pitfalls.
Millions of tonnes of outdated and broken solar panels will need to be recycled in the near future. Italian technology startup 9-Tech has a method to recover valuable materials such as silicon .
Incorrect information about toxic materials in PV modules is leading to unsubstantiated claims about the harms that PV modules pose to human health and the environment, fuelling public concern.
