About the technology
Heterojunction (HJT) solar technology combines crystalline silicon with thin amorphous silicon layers, enhancing performance and efficiency. This innovative approach enables HJT cells to achieve higher energy conversion rates and perform better under high temperatures.
HJT solar cells utilize n-type wafers, which eliminate light-induced degradation (LID), and their indium tin oxide layer is conductive, preventing potential-induced degradation (PID). Additionally, HJT technology is less susceptible to temperature fluctuations, making it particularly suitable for high-temperature environments that typically degrade the performance of standard crystalline silicon (c-Si) modules.
Advantages of HJT
? Higher Efficiency: HJT cells capture more light and convert it to electricity more effectively than traditional cells. ASTORIOS HJT PV modules boast a remarkable 23.9 % maximum module efficiency.

? Lower Temperature Coefficient: They perform better at higher temperatures, maintaining efficiency where other cells lose power.
? Bifacial Capability: Thanks to its natural bifacial symmetrical structure, HJT solar modules can achieve bifaciality of up to 97%, with energy yield gains exceeding 30% due to rear-side power generation. This makes HJT technology increasingly popular for utility-scale applications that capitalize on albedo resources.
? Technological advancements have made HJT cell production more cost-effective and sustainable.
? Passivation: The amorphous silicon layers passivate the silicon wafer's surface, reducing recombination losses and improving overall efficiency.
HJT technology represents a significant advancement in solar cell design, combining the benefits of crystalline and thin-film technologies to deliver high efficiency, improved temperature performance, and increased energy output.
