How to improve the stability of perovskite solar cells under water and moisture exposure?
Herein, a method to improve the stability of perovskite solar cells under water and moisture exposure consisting of the encapsulation of the cell with an ultrathin plasma polymer is reported. The deposition of the polymer is carried out at room temperature by the remote plasma vacuum deposition of adamantane powder.
Do perovskite solar cells have water molecules?
Perovskite solar cells (PSCs) have attracted wide publicity via their excellent photoelectric properties. Nevertheless, the relative low formation energy and soft lattice of perovskite make it vulnerable to external environmental factors, especially the moisture. Inevitably, water molecules would remain in PSCs modules during practical production.
Do halide perovskite films and solar cells have moisture stability?
The moisture stability of halide perovskite films and solar cells is reviewed. The water effects on perovskite solar cells are systematically discussed. Recent measures taken to improve the moisture stability are summarized. The challenges and outlooks towards more stable PSCs are proposed.
Does perovskite degrade solar cell performance?
Not only perovskite but the presence of moisture can also degrade the HTMs which also leads to further drop in the solar cell performance. The 2,2′,7,7′-tetrakis (N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (Spiro-OMeTAD) is the most commonly used HTM in the regular n–i–p structured PSCs.
Are perovskite solar cells commercially scalable?
First published on 12th February 2024 Efficiency and stability are the two most important factors in commercially scalable solar cells. In spite the high-power conversion efficiencies (PCE), the commercialization of perovskite solar cells (PSC) has been limited due to their low stability under ambient conditions.
How do perovskites react with water?
Perovskites readily react with water/moisture, that causes degradation into their precursor materials or formation of hydrated phases and results in lower power output and short circuit in the solar cells.2–4 Perovskites are susceptible to chemical decomposition from moisture due to the presence of hygroscopic ammonium and Pb (II) salts.
