The manufacturing typically starts with float glass coated with a transparent conductive layer, onto which the photovoltaic absorber material is deposited in a process called close-spaced sublimation.
Solar panels or PV modules are made by assembling solar cells into a frame that protects them from the environment. A typical PV module consists of a layer of protective glass, a layer of cells and a backsheet for insulation. In silicon PV module manufacturing, individual silicon solar cells are soldered together, typically in a 6×10 configuration.
Module Assembly – At a module assembly facility, copper ribbons plated with solder connect the silver busbars on the front surface of one cell to the rear surface of an adjacent cell in a process known as tabbing and stringing.
