In a study published in ACS Applied Materials & Interfaces, a research group led by GUO Xiaoyang from the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) of the Chinese Academy of Sciences (CAS) proposed a new idea to achieve high-efficiency perovskite light-emitting diodes by tuning the low-dimensional phase composition.
In a study published in Optics and lasers in Engineering, a research group led by Prof. ZHANG Xuejun from the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) of the Chinese Academy of Sciences (CAS) proposed the concept of wavefront optical spacing (WOS), and a cat-eye computer-generated hologram (CGH) test method.
Multi-junction and tandem photovoltaic (PV) cells are developed to overcome the single-junction Shockley–Queisser (SQ) limit. Spectral splitting is the key to achieve high conversion efficiencies in these cells. In a typical tandem solar cell, the incident light is spectrally splitted between the upper and lower cells. Through an intelligent selection of materials, the number of layers, and the design of an efficient optical cavity, photons from the entire solar spectrum can be efficiently harvested.
