The Prospects of BC Photovoltaic Cells
BC cells have attracted great interest in the photovoltaic field with their unique design. Compared with traditional photovoltaic cells, the front of BC cells uses a double-layer SiNx/SiOx anti-reflection passivation film without metal grid lines, while the emitters and back fields of P+ and N+ as well as the positive and negative electrodes of the corresponding areas are arranged on the back of the cell. This design avoids the light blocking by the metal grid electrode on the front, maximizes the use of incident light, reduces optical losses, and thus improves the photoelectric conversion efficiency. The theoretical conversion efficiency limit of BC cells is higher than other technologies, showing great potential in the future photovoltaic market.
Companies such as Longi Green Energy have stated that BC batteries are expected to become the mainstream technology route in the next 5-6 years, replacing TOPCON batteries and becoming the absolute mainstream of crystalline silicon batteries. However, due to the relatively complex manufacturing process of BC batteries, the relatively high equipment cost, and the relatively slow industrialization process, it is still in its infancy. However, the gradual popularization of BC batteries will inject new impetus into the development of clean energy.
