To calculate a percentage of a percentage, convert both percentages to fractions of 100, or to decimals, and multiply them.

A full area metal contact is made on the back surface, and a grid-like metal contact made up of fine "fingers" and larger "bus bars" are screen-printed onto the front surface using a silver paste. This is an evolution of the so-called "wet" process for applying electrodes, first described in a US patent filed in 1981 by Bayer AG . [ 159 ]
