Shenzhen HIKING PV Technology Co., Ltd.——In the continuous innovation within the photovoltaic technology sector, the company has achieved another remarkable accomplishment in the field of triple-junction tandem solar cells. Authorized third-party certification confirms that the company’s developed triple-junction tandem solar cell has achieved a conversion efficiency of 28.2%, setting a new world record.
This breakthrough marks a new height in photovoltaic technology and lays a solid foundation for the company’s future development.
Compared to two-junction tandem solar cells, triple-junction tandem solar cells present significantly greater technical challenges. Their design requires a high degree of synergy in material matching, spectral utilization, and manufacturing processes. However, triple-junction tandem solar cells hold greater potential in theoretical efficiency, making them a critical area for future competition in the photovoltaic market and a key direction for technological development.
The company points out that future development through continuously stacked two-terminal (2T) tandem solar cells balances both cost and performance:
• Cost Advantage: No need for additional electrodes and other layers, saving manufacturing costs；
• Optical Transmission Advantage: The design without additional blocking layers allows for superior light penetration.
Nevertheless, the challenges lie in the higher technical barriers. However, technological breakthroughs in this field will bring stronger market competitiveness and commercial value to the photovoltaic industry.
