Solar cell efficiency in various types

      From the perspective of the evolution of photovoltaic cells, the industry usually divides photovoltaic cells into three generations. The first-generation battery is currently popular silicon-based solar cells, mainly composed of monocrystalline silicon solar cells and polycrystalline silicon solar cells, and the second-generation cells are mainly thin-film inorganic compound solar cells.

      Compared with conventional crystalline silicon cells and the current popular p-type PERC cells, HIT cells have many advantages, such as high efficiency, no light attenuation, low temperature coefficient and high light reactivity. Low light. The most obvious feature brought about by these advantages is that the HIT battery has a higher power generation capacity.                                                  

      Under the same power source, the power generation capacity of the HIT battery is also stronger. Due to its low temperature coefficient, no degradation and strong response to weak light, HIT batteries can generate more power than other types of modules with the same capacity, 10% higher than single crystal PERC modules, and higher than single crystal PERC modules 5% higher. PERC-10%. At the same time, the double ratio of HIT modules is higher. If double-sided power generation is considered, the HIT module has higher power generation efficiency.
