Born in Paris, Becquerel was the pupil-turned-successor of his father at the Muséum national d'histoire naturelle. He was also appointed professor at the short-lived Agronomic Institute in Versailles in 1849, and in 1853, received the Chair of Physics at the Conservatoire des arts et métiers. He was associated with his father in much of his work.

In 1839, at age 19, while experimenting in his father's laboratory, Becquerel created the world's first photovoltaic cell. In this experiment, he placed silver chloride in an acidic solution and illuminated it while it was connected to platinum electrodes, thus generating voltage and current. Because of this work, the photovoltaic effect has also been known as the "Becquerel effect".

Becquerel paid special attention to the study of light, investigating the photochemical effects and spectroscopic characters of solar radiation and the electric arc light, and the phenomena of phosphorescence, particularly as displayed by the sulfides and by compounds of uranium. It was in connection with these latter inquiries that he devised his phosphoroscope, an apparatus which enabled the interval between exposure to the source of light and observation of the resulting effects to be varied at will and accurately measured. He investigated the diamagnetic and paramagnetic properties of substances and was keenly interested in the phenomena of electrochemical decomposition, accumulating much evidence in favor of Faraday's law of electrolysis and proposing a modified statement of it which was intended to cover certain apparent exceptions. In 1853, Becquerel discovered thermionic emission.

Edmond Becquerel was recorded at birth as Alexandre-Edmond Becquerel. The authorities additionally record the headings Alexandre Edmont Becquerel, Alexandre-Edmond Becquerel and E. His recorded language was French. He was the child of Antoine César Becquerel. One child is recorded: Antoine Henri Becquerel.

Edmond Becquerel worked in physics. He was employed by Muséum national d'histoire naturelle. Recorded positions include president and president of the French Academy of Sciences. He belonged to Royal Society, Société Philomathique de Paris, Royal Swedish Academy of Sciences, French Academy of Sciences and Société héliographique.
