Heterojunction (HJT) solar cells are advanced photovoltaic devices that combine the benefits of crystalline silicon (c-Si) and thin-film technologies. HJT cells feature a unique structure where a thin layer of amorphous silicon (a-Si) is deposited on both sides of a c-Si wafer. This configuration allows for efficient charge carrier separation, reduced recombination losses, and enhanced light absorption. HJT solar cells offer high conversion efficiencies, excellent performance in low-light conditions, and potential for cost reduction, making them a promising solution for solar energy generation.

Temperature Co-efficient

The low-temperature coefficient is a desirable characteristic in solar modules that refers to the minimal decrease in power output with decreasing temperature. Solar modules with a low-temperature coefficient offer several advantages. Firstly, they exhibit improved performance in colder climates, where temperatures can negatively impact the efficiency of solar cells. Secondly, they maintain higher power output during hot summer days, preventing significant drops in energy production. This characteristic ensures more consistent and reliable performance, maximizing the energy yield and overall efficiency of the solar system regardless of temperature fluctuations.
