The First Photovoltaic Device
In 1839, at age 19, experimenting in his father's laboratory, Bequerel built the world's first photovoltaic. In this experiment, silver-chloride was place in an acidic solution and illuminated while connected to platinum electrodes, thus generating photovoltage and photocurrent. Due to this work, the photovoltaic effect has also been known as the "Becquerel Effect."

Famous quotes containing the word device:
“Syntax is the study of the principles and processes by which sentences are constructed in particular languages. Syntactic investigation of a given language has as its goal the construction of a grammar that can be viewed as a device of some sort for producing the sentences of the language under analysis.”
—Noam Chomsky (b. 1928)
