Fiber-Shaped Perovskite Solar Cells with High Power Conversion Efficiency

Abstract

A perovskite solar cell fiber is created with a high power conversion efficiency of 7.1% through a controllable deposition method. A combination of aligned TiO2 nanotubes, a uniform perovskite layer, and transparent aligned carbon nanotube sheet contributes to the high photovoltaic performance. It is flexible and stable, and can be woven into smart clothes for wearable applications.

Fiber‐Type Solar Cells, Nanogenerators, Batteries, and Supercapacitors for Wearable Applications

“…Another interesting approach to make efficient FPESC is a cathodic deposition technique 70. The advantage of this approach is that a uniform layer of perovskite can be obtained on curved surfaces.…”

Flexible organic-inorganic hybrid perovskite solar cells

“…Later on in 2016, they used TiO 2 nanotubes as ETL and deposited the perovskite layer by electrochemical deposition process. The greater density perovskite grains induced a higher PCE of fiber solar cell to 7.1% with a V oc of 0.85 V [28]. …”

“…Other types of miniature energy harvesting devices,such as one-dimensional solar cells [16,[19][20][21][22] and electrostatic and triboelectric nanogenerators, [23][24][25][26] have been previously investigated. For solar cells,o nly one side can be illuminated to harvest sunlight during use.A dditionally,t he availability of sunlight is only during daytime.…”

Fort he OMC-incorporated FFNG, owing to the large surface area, the OMC provides ah igher capacity for ion adsorption, which allows for the generation of alarger potential difference.T overify this hypothesis,w ei nvestigated the cyclic voltammograms of the FFNG with increasing OMC contents in at hree-electrode electrochemical cell.…”
