The process of making solar panels is very precise and delicate, This is the reason why solar technology was so expensive when photovoltaic devices were first commercialized. The mass production of solar technology did not occur until the very last quarter of the last century, when breakthrough advancements in semiconductors and solar designs made way for progressively efficient and affordable photovoltaic cells to be developed.

Photovolatic cells are thin disks of silicon that transfer sunlight into electricity. Pure silicon is transmitted from silicon dioxides like crushed quartz and quartize gravel, which is the purest form of silica. The pure silicon is when treated with boron and phosphorous to create and overabundance of electrons and an inadequacy of electrons as well in order to generate a semiconductor that is capable of administering electricity. The silicon disks are so shiny that they need an anti-reflective coating, which usually comes in the form of titanium dioxide. A metal frame surrounds and protects the silicon semiconductor. The frame itselg is made of either butyryl plastic or silicon rubber, which is then planted in ethylene vinyl acetate. Then, polyester film, like tedlar of mylar, is used for the backing. The electrical components are pretty basic and mostly consist of copper. Silicon is basically the cement that holds all of the pieces together.
