To make a silicon solar cell, blocks of crystalline silicon are cut into very thin wafers. The wafer is processed on both sides to separate the electrical charges and form a diode, a device that allows current to flow in only one direction. The diode is sandwiched between metal contacts to let the electrical current easily flow out of the cell.
Chapter 3. In most of today solar cells the absorption of photons, which results in the generation of the charge carriers, and the subsequent separation of the photo-generated charge carriers take place in semiconductor materials. Therefore, the semiconductor layers are the most important parts of a solar cell; they form the hart of the solar cell.
