Although larger size solar cells allow for more W/m 2 of solar irradiance absorption, working with such cells has many disadvantages from operational point of view (larger size allows more recombination events and longer distance to reach contacts which will decrease efficiency).

Creating a silicon solar cell is an intricate process that requires precision and care. Silicon, which is commonly found in sand, must be purified until it’s almost completely clean. This highly purified silicon is then used to grow a silicon crystal, which is subsequently cut into thin wafers.
Wafer preparation Once the monocrystalline or multicrystalline ingots are fabricated, they must be shaped and sawed into wafers for subsequent solar cell fabrication. This process implies a material loss. First, the head and tail of the ingot are discarded, and the ingot is given a square shape by cutting off the edges.
A solar cell has a large area of a p-n junction. Solar cell formation starts with p-type Silicon that is obtained from the previously mentioned process, in which a p-doped ingot is formed and then cut into wafers. The non-uniformed and uneven surface of the wafers is cleaned up for the next process, which is called surface texturing.
A solar cell fabrication process uses several high-temperature steps including a phosphorus diffusion process and a metal contact firing. The silicon wafer is p-type doped to 1 · 10 15 cm −3. The required surface doping and depth for the diffused part of the pn junction are 1 · 10 19 cm −3 and 200 nm, respectively.
