Advanced technologies used in glass-glass solar panels

Several advanced technologies contribute to the superior performance of glass-glass solar panels, including Belinus' offerings. By incorporating Interdigitated Back Contact (IBC) technology, Heterojunction Technology (HJT), and ultra black solar cells, these panels achieve higher efficiency and better energy yield.

1. Interdigitated Back Contact (IBC) technology

IBC technology involves placing all the electrical contacts on the rear side of the solar cell. This eliminates shading caused by the front-side metal contacts, allowing the cell to capture more sunlight and produce more energy. Furthermore, IBC technology reduces the internal resistance of the cell, resulting in higher conversion efficiency.

2. Heterojunction Technology (HJT)

HJT combines the advantages of crystalline silicon (c-Si) and amorphous silicon (a-Si) in a single solar cell. This technology uses thin layers of a-Si on either side of the c-Si wafer to form a highly efficient junction for converting sunlight into electricity. HJT solar cells exhibit excellent temperature coefficients, leading to better performance in hot environments, and higher energy yield throughout the day.

3. Ultra black solar cells for increased light absorption

Ultra black solar cells are designed to absorb up to 99.7% of available sunlight. These cells feature an anti-reflective coating that minimises reflection losses and maximises light absorption, resulting in greater energy production. The improved light absorption of ultra-black solar cells contributes to the enhanced efficiency of glass-glass solar panels.

4. Role of these technologies in Belinus' glass-glass solar panels
