Scientists from Hong Kong University of Science and Technology(HKUST) have developed a solvent-free manufacturing technology for perovskite solar cells. This innovation has been made public in February 2026. The technology is expected to enhance the large-scale manufacturing of perovskite solar cells and make them more environmentally friendly.
Perovskite solar cells are famous for their efficiency and low manufacturing costs. But the traditional manufacturing process is dependent on toxic solvents. These solvents are environmentally hazardous and raise concerns about sustainability. The new technology developed by HKUST eliminates the use of solvents in the manufacturing of these solar cells. The research team at HKUST has designed a dry processing method for the manufacturing of these solar cells. This method enables the team to produce these cells without using any liquid chemicals. This technology is easy to implement and uses less energy.
The initial results revealed encouraging levels of power conversion efficiency. The solar cells performed well while also exhibiting improved resilience against heat and humidity. The challenge of stability has been one of the most significant commercial hurdles for perovskite solar cells. This breakthrough can resolve this problem. According to HKUST, the new method is scalable using appropriate manufacturing equipment. The technology has the potential to be applied to tandem solar cells, where perovskite materials are stacked with silicon solar cells to enhance overall efficiency.
Industry experts believe that this is a major breakthrough towards more environmentally friendly solar cell manufacturing. With the growing demand for high-efficiency clean energy solutions, the HKUST breakthrough further propels the perovskite solar cell industry. The emphasis is now on scaling up and collaborating with manufacturers for commercialization.
