The three main advantages of BC battery technology
The advantages of BC battery technology are mainly reflected in three aspects. Let's take a look:
The structural feature of the BC battery is the absence of gridlines on the front. This front unobstructed structure completely eliminates shading losses caused by gridline electrodes, maximizing the utilization of incident photons. This can improve the short-circuit current (Jsc) by about 7% compared to conventional solar cells.
The module packaging is more convenient and flexible. The traditional "Z" shaped welding is replaced by a full-back "I" shaped welding, avoiding the conventional complex packaging process. Additionally, it effectively enhances the module's resistance to microcracks. For example, the edge stress of Longi's HPBC battery is reduced by 48% compared to traditional non-BC battery cells.
The appearance is aesthetically pleasing, with a more uniform and attractive front tone.
These are the three main advantages of BC battery technology introduced by Hengyuantai.
