This industrial research sheds light on the manufacturing of monocrystalline silicon solar cells, the optimization of the weight of the cell during manufacturing, and the effect of each stage of manufacturing on the color and weight of the solar cell. During manufacturing, the solar cell goes through six stages: texturing, diffusion, plasma etching, remove phosphorous silicate glass (RPSG), anti-reflection coating (ARC), and screen printing. The success of each stage determines the cell weight and cell color. This weight of the cell depends on the weight of the silicon wafer (p-type) and each stage from the manufacturing stages affects this weight. After many experiments were carried out, we found that some stages lead to weight gain and some stages that lead to weight loss. The texturing stage leads to weight loss ranging from 0.7 to 1.1 grams, it is the most stage leads to weight loss. The diffusion stage leads to a slight weight gain ranging from 0.008 to 0.0148 grams. The plasma etching stage leads to a slight weight loss ranging from 0.0005 to 0.005 gram. RPSG stage leads to a small loss of weight ranging from 0.0151 to 0.0176 gram. ARC stage leads to a slight weight gain ranging from 0.004 to 0.0123 grams. Screen printing leads to weight gain, screen printing 1 leads to weight gain from 0.0039 to 0.0084 grams, screen printing 2 leads to weight gain from 1.122 to1.3grams, , screen printing 3 leads to weight gain from 0.0782 to 0.0865 grams.
