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
Perovskite solar cells (PSCs) are developed rapidly in efficiency and stability in recent years, which can compete with silicon solar cells. However, an important obstacle to the commercialization of PSCs is the toxicity of lead ions (Pb 2+) from water-soluble perovskites.
Today, the use of lead is severely restricted, and banned for certain applications where it can not practically be prevented from leaking into the environment, in jurisdictions including the United States, European Union and Japan. In spite of this, a typical 60-cell crystalline silicon solar module produced today contains up to 12 grams of lead.
Lead halide perovskite solar cells (PSCs) have drawn worldwide attention due to their high absorption coefficients, long charge carrier diffusion lengths, and high defect tolerance. The certified power conversion efficiency (PCE) of PSCs has jumped to 25.7% in the last decade.
