Template growth of perovskites on yarn fibers induced by capillarity for flexible photoelectric applications

Abstract

“Quasi-spring” network structured perovskite materials were fabricated by a capillary effect driven template synthesis method for flexible photoelectric applications.

Highly Efficient White‐Light Emission Triggered by Sb3+ Dopant in Indium‐Based Double Perovskites

“…Metal (M) halide (X) perovskites (AMX 3 , A ¼ MA, FA, Cs), which have metal-centered octahedra as building blocks, have been extensively studied as functional materials in various optoelectronic devices, such as the absorption layer of solar cells, light-sensing layer of photodetectors, and light-emitting layer of white-light-emitting diodes (WLEDs), due to their good electronic properties. [1][2][3][4][5][6][7][8][9] However, in addition to problems regarding electrical and chemical instability, the toxicity of the lead content poses a major environmental problem for device applications. [10][11][12][13] To address these problems, inorganic double perovskites, formed by transmuting the divalent lead cation (Pb 2þ ) sites into a combination of monovalent (M I ) and trivalent (M III ) sites or trivalent (M III ) and vacancy (□) sites to form double (Cs 2 M I M III X 6 ) and triple (Cs 3 □M III 2 X 9 ) perovskites (DPs and TPs), have emerged.…”

A Perspective on the Commercial Viability of Perovskite Solar Cells

“…Continuous development of fPSCs into fibrous PSCs thread/yarn, which can be knit into wearable products, were foreseen for future development of wearable electronics. [234][235][236] Such wearable PSCs technology must withstand substantial bending, twisting, stretching, and folding while retaining its PCE in line with recent recommendation of Tebyetekerwa et al on flexible charge storage devices. [237] Unfortunately, techniques to turn flexible PSCs into yarns/threads would add additional cost to the overall cost of wearable PSCs, which will be further discussed in Section 2.3.…”
