In 1823 for the first time Jacob Berzelius discovered silicon tetrachloride (SiCl 4). [27] In 1846 Von Ebelman's synthesized tetraethyl orthosilicate (Si(OC 2 H 5) 4). [28] [27] Single crystal of silicon grown by the Czochralski process used to make integrated circuits. Silicon in its more common crystalline form was not prepared until 31 years ...
The MOSFET was invented at Bell Labs between 1955 and 1960, after Frosch and Derick discovered surface passivation by silicon dioxide and used their finding to create the first planar transistors, the first in which drain and source were adjacent at the same surface.
Silicon cycle and balance in the modern world ocean [1] Input, output, and biological silicon fluxes, with possible balance. Total silicon inputs = total silicon outputs = 15.6 Tmol Si yr −1 in reasonable agreement with the individual range of each flux.

1981 - Isofoton is the first company to mass-produce bifacial solar cells based on developments by Antonio Luque et al. at the Institute of Solar Energy in Madrid. [20] 1982 - The first >10% amorphous silicon thin film solar cell is reported. [21] 1983 - Worldwide photovoltaic production exceeds 21.3 megawatts, and sales exceed $250 million.
