Huarou PV

Huarou PV is mainly engaged in the research and development of new solar cell technologies. It aims to develop a new generation of lightweight and flexible solar cell technology and realize the integration of various electronic products.

HuaRou PV's main business includes:
(1) Sales of new solar cell related materials;
(2) R&D and sales of new solar cell preparation and testing equipment;
(3) Technical services and technology development related to new solar cell technology.

In March 2026, Huarou PV reported a conversion efficiency of 27.98% for its self-developed single-junction perovskite solar cell, certified by the National PV Industry Measurement and Testing Center (NPVM). The test device has an area of 0.051 m² and was measured under standard illumination conditions.

According to shareholder Ouhai Sci-tech Group, the result represents the first time a perovskite solar cell has exceeded the laboratory efficiency of all single-junction crystalline silicon cells. For comparison, the previous record of 27.9% was achieved by LONGi in 2025 using its HTBC structure and verified by Germany’s Institute for Solar Energy Research Hamelin (ISFH), later included in the Solar Cell Efficiency Tables (Version 67).
