A research team from Tianjin University of Technology, Shandong Univeristy and Shantou University has developed a novel method to enhance the performance and durability of inverted perovskite solar cell (PSC). By introducing guanidinium salt into the fabrication process, the team successfully controlled crystal growth and orientation, leading to solar cells with higher efficiency (25.85%), improved charge transport and exceptional stability under humid and thermal conditions. Moreover, extensive testing demonstrated that the devices retain over 95% of their original efficiency after thousands of hours of operation and exposure to challenging environments.

This work offers a reliable approach to fabricating highly oriented, low-defect perovskite films, accelerating the development and commercialization of efficient and stable PSCs.

Micro display is one of the important components of AR glasses. Micro-QLED is emerging as promising AR display technology due to its wide luminance range, facile fabrication of high-resolution and full-color patterns. Scientist from Beijing Institute of Technology reported the fabrication of color-converted Micro-QLED which provides a simple and low-cost route to achieve full-color micro display.
