The manufacturing process of PV solar cells necessitates specialized equipment, each contributing significantly to the final product’s quality and efficiency: Silicon Ingot and Wafer Manufacturing Tools: These transform raw silicon into crystalline ingots and then slice them into thin wafers, forming the substrate of the solar cells.
Central to this solar revolution are Photovoltaic (PV) solar cells, experiencing a meteoric rise in both demand and importance. For professionals in the field, a deep understanding of the manufacturing process of these cells is more than just theoretical knowledge.
Solar Photovoltaic (SPV) modules occupy an important position in the value chain [1–5] (see Figure 9.1). Crystalline silicon (c-Si) is currently the preferred technology with a market share of about 85%. c-Si modules are made using crystalline silicon (Si) solar cells as the starting material. Several such cells are connected to make modules.
At their core, PV cells are made of semiconductor materials, typically silicon, which is abundant and effective in converting sunlight into electricity. These semiconductors are doped with other elements to create positive (p-type) and negative (n-type) layers, which are essential for generating an electric field.
Most new photovoltaic manufacturing capacity added in the second half of 2021 was N-Type TOPCon based, making TOPCon the cell technology with the second-highest production capacity in 2022, with the latest industry roadmap anticipating N-type TOPCon will become the dominant commercial cell technology by 2023.
Solar Photovoltaic Lamination: In this critical phase, the cells are encapsulated within laminated glass or other protective materials. This solar module lamination not only protects the cells from environmental factors but also enhances their overall performance and longevity.
