Crystalline silicon (c-Si) solar cells are among the most promising solar technologies on the market. These solar cells have numerous advantageous properties, including a nearly optimum bandgap, high efficiency and stability. Notably, they can also be fabricated using raw materials that are widely available and easy to attain. In recent years, many companies and engineers specifically focused their research efforts on Si heterojunction (SHJ) solar cells. These solar cells, which consist of amorphous silicon layers deposited on crystalline silicon surfaces, have been found to achieve remarkable power conversion efficiencies (PCE).
