Photovoltaic Cell is an electronic device that captures solar energy and transforms it into electrical energy. It is made up of a semiconductor layer that has been carefully processed to transform sun energy into electrical energy. The term "photovoltaic" originates from the combination of two words: "photo," which comes from the Greek word "phos," meaning

Insufficient toxicity and environmental risk information currently exists. However, it is known that lead (PbI 2), tin (SnI 2), cadmium, silicon, and copper, which are major ingredients in solar cells, are harmful to the ecosystem and human health if discharged from broken products in landfills or after environmental disasters.
Solar photovoltaic power is not entirely "clean energy": production produces greenhouse gas emissions, materials used to build the cells are potentially unsustainable and will run out eventually, [clarification needed] [citation needed] the technology uses toxic substances which cause pollution, [citation needed] and there are no viable technologies for recycling solar waste.
However, this ramp-up in deployment has led to growing concerns about PV waste and toxicity. Communities, government agencies, and policymakers worry about the quantity of waste that could arise from decommissioning PV modules, as well as their potential to leach toxic metals.
Toxic chemical compounds are used to clean the semiconductor wafers that make up the photovoltaic (PV) cell. These include hydrofluoric and sulfuric acid. This cleaning step is essential to remove damage and produce the right surface texture. However, hydrofluoric acid is deadly to an unprotected individual, being capable of corroding tissue
A solar cell, also known as a photovoltaic cell (PV cell), is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. [1] It is a form of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is exposed to light. Individual solar cell devices are often the electrical

Central to this solar revolution are Photovoltaic (PV) solar cells, experiencing a meteoric rise in both demand and importance.

It is also an important tool in optimizing their application and maximizing efficiency in a wide range of
The manufacturing of PV solar cells involves different kinds of hazardous materials during either the extraction of solar cells or semiconductors etching and surface cleaning (Marwede et al., 2013; Üçtuğ and Azapagic, 2018).
Examples of these chemicals are hydrogen, hydrochloric acid, nitric acid, isopropanol, ammonia, and selenium hydride. Most of these compounds are flammable, corrosive, toxic, and carcinogenic, hence they require special handling. The emissions of these hazardous gases and chemical solvents vary with the type of PV cell materials.
In line with these innovations, there are concerns about greenhouse gas emissions of the solar cells, materials for the solar technologies and other relevant environmental impacts of the manufacturing processes. This review is conducted on life cycle assessments of solar cells, considering the climate change and natural resource shortage context.
The majority of PV plant equipment is supplied using fossil fuel-based power generation, which is linked to greenhouse gas emission and the production of other environmental pollutants. More pollution occurs during the transportation, installation and maintenance of the equipment.
However, this ramp-up in deployment has led to growing concerns about PV waste and toxicity. Communities, government agencies, and policymakers worry about the quantity of waste that could arise from decommissioning PV modules, as well as their potential to leach toxic metals.
Heather Mirletz, a researcher in circular economy and sustainability of PV at the National Renewable Energy Laboratory (NREL), goes on to tell PV Tech Premium that the most prevalent concerns around PV toxicity may soon become irrelevant.
