Dye-sensitized solar cells under ambient light powering machine learning: towards autonomous smart sensors for the internet of things

“…S8 †). 25,[50][51][52] We measured Raman spectroscopy directly inside the 'sandwich' solar cell to investigate the Cu II/I (tmby) 2 hole transport material (Fig. 4).…”

In Depth Analysis of Photovoltaic Performance of Chlorophyll Derivative-Based “All Solid-State” Dye-Sensitized Solar Cells

“…− /I − redox shuttle [15,16]. DSSCs incorporating solid-state hole transport materials (HTMs) have been actively investigated [17][18][19], and decent efficiencies close to 12% have been already achieved by molecular and inorganic HTMs combined with state-of-the-art organic dyes [20,21]. Additionally, solid-state DSSCs (ssDSSCs) led to a major breakthrough by using hybrid lead halide perovskite sensitizers such as CH 3 NH 3 PbI x Cl 3-x , enabling the advent of perovskite solar cells with efficiencies now above 25% [22].…”

Nanoscale Perovskite‐Sensitized Solar Cell Revisited: Dye‐Cell or Perovskite‐Cell?

“…The most successful example of a sensitized solar cell came from a seminal report in 1991, in which molecular dyes anchored onto the surface of mesoscopic TiO 2 film as a photosensitizer produced significant current by injecting charges into each electron‐ and hole‐transporting material after absorbing incident light . This dye‐sensitized solar cell (DSSC) also evolved first as a liquid type and then a solid type using solid‐state hole‐transporting material, among which the most successful one was Spiro‐OMeTAD {2,2′,7,7′‐tetrakis[ N , N ‐di(4‐methoxyphenyl)amino]‐9,9′‐spirobifluorene} . Later, semiconducting quantum dots (QDs) also attracted much attention as a replacement for typical molecular dyes toward a new class of inorganic photosensitizer in the same DSSC structure and have shown promising results recently in a liquid‐type cell after many trials .…”

“…Meanwhile, molecular dye‐ or inorganic QD‐sensitized solid‐state (ss) solar cells based on mesoporous metal‐oxide films have experienced a very slow rise in overall power conversion efficiencies (PCEs) although their importance was clearly recognized in terms of using stable solid hole‐conductors relative to volatile liquid electrolytes . PCEs of typical ss‐DSSCs with Spiro‐OMeTAD as the best hole‐transporting material (HTM) have steady risen up to approximately 7.5 % over 1.0–2.0 μm thick TiO 2 film during the last two decades since the first report of 1.8 % .…”
