Kingyoup Optoelectronics launched the world’s first generation of 6-line perovskite vacuum coating machine, which is the world’s largest perovskite-specific production equipment (substrate size 1,850*1,500mm), with a unique reaction chamber and ultra-low substrate temperature control design. Lai-Juh Chen, vice chairman and chief of the strategy office of Kingyoup Optoelectronics, said that this sixth-generation line equipment has been evaluated by world's leading manufacturers and the trial production has been successful.
Lai-Juh Chen, who is also the chairman of Taiwan Perovskite Technology, which was established this year, stated that Kingyoup Optoelectronics and Taiwan Perovskite Technology (TPSC) have launched integrated innovative equipment and material technology in response to the third generation of solar energy. Recently at Energy Taiwan exhibition, Lai-Juh Chen announced that "Perovskite solar cells, combined with domestically-made independent equipment, materials, and process one-stop solutions (total solutions), are extremely breakthrough."
Lai-Juh Chen pointed out that the biggest challenge for the global perovskite solar cell industry today is how to stably coat the perovskite layer on large-scale substrates. TPSC has successfully developed a new technology that can remove imperfect or defective thin films through special equipment. Through these special equipment processing, the film characteristics are uniform, and the engineering design with convergent photoelectric characteristics can meet the needs of large-area perovskite solar mass production.
TPSC cooperated with equipment manufacturer Kingyoup Optoelectronics to develop an exclusive large-area film modification treatment technology, and further developed a unique low-toxic water-based formula. Compared with traditional high-toxic solvent, low-toxic water-based one can greatly reduce the barriers of mass production operability, being a safer and more convenient material to operate, thus allowing more flexibility in the development of large-area mass production equipment in the future.
According to Lai-Juh Chen, the low-toxicity aqueous solution formula and the large-area thin-film modification technology have enabled the mass production technology of large-area perovskite solar cells to take a big step forward, which has received enthusiastic responses from industry experts.
A few days ago, at the Energy Week exhibition, Lai-Juh Chen and the TPSC chief technical adviser Dr. Tzu-Chien Wei stated that the photoelectric conversion efficiency of the new structure of perovskite solar cells has rapidly increased from 3.8% to nearly 25% within 10 years. It can even keep pace with the long-developed silicon crystal type and third and fifth generation of solar cells. During the fast-growing third-generation solar cell production process, there are some challenges in materials, equipment, and manufacturing processes, which are opportunities for Taiwanese companies to invest…
Lai-Juh Chen pointed out that TPSC will establish a large-area pilot line in the future and continue to develop and study the integration of next-generation materials, equipment and manufacturing processes on the pilot line. At the same time, it will also combine with Taiwan’s silicon solar industry to challenge for higher-efficiency next-generation solar cells.
