DSSC(色素増感太陽電池)研究

0) DSSCとは? / What is a DSSC?

日本語(やさしく)

  • DSSC(色素増感太陽電池)は、「色素が光を吸収 → 電子を半導体へ渡す → 電解質が色素を再生する」という流れで発電します。
  • 強い日差しだけでなく、条件次第では室内光でも働きやすく、材料や製造法の工夫で低コスト化が期待されます。

English (plain)

  • A dye-sensitized solar cell (DSSC) converts light to electricity by: dye absorption → electron injection into a semiconductor → dye regeneration by the electrolyte.
  • DSSCs can be attractive for low-cost fabrication and can operate under indoor/light scenarios depending on design.

1. Synthesis, photophysical, electrochemical, and quantum chemical investigations of a novel phenothiazine-derived organic dye for high efficiency dye-sensitized solar cells

  • 掲載誌:Journal of Physics: Energy(JIF 6.3)
  • :2026
  • DOI:10.1088/2515-7655/ae512a
    ポイント(わかりやすい箇条書き)
  • 狙い:有機色素の“形”と“電子の流れ”を設計して、DSSCの発電性能を高める。
  • 方法:フェノチアジン骨格を基盤に新規色素を合成し、分光・電気化学測定と量子化学計算(DFT等)で性質を評価。
  • ポイント:分子が平面に寄りすぎない構造は、色素の凝集を抑えやすく、電子注入・再結合のバランス最適化につながる。
  • 意味:高価な金属錯体色素に頼らない“金属フリー色素”の選択肢を広げる。

  • 狙い:水質浄化(光触媒)と太陽電池(DSSC)の両方で役立つ“多機能材料”をつくる。
  • 方法:ZnOにCdSとg-C3N4を組み合わせた三元複合体を合成し、光吸収・電荷分離・界面輸送を強化。

  • DOI:10.25259/AJC_311_2025
    ポイント(わかりやすい箇条書き)
  • 課題:単一色素では吸収できる光の範囲が限られ、界面での電荷再結合も起こりやすい。
  • 方法:新しいチアゾール系有機色素(トリフェニルアミン系/フルオレン系)をN719と「共増感」し、さらにCDCA(共吸着剤)で色素凝集を抑制。
  • 結果:共増感でPCEが約7.9%まで向上し、CDCA併用で最大9.93%に到達(ファイル記載値)。
  • 意味:分子設計+界面制御の組合せが、低コストDSSCの効率・安定性を押し上げる有効策になる。

1. Synthesis, photophysical, electrochemical, and quantum chemical investigations of a novel phenothiazine-derived organic dye for high efficiency dye-sensitized solar cells

  • Journal: Journal of Physics: Energy (JIF 6.3)
  • Year: 2026
  • DOI: 10.1088/2515-7655/ae512a
    Key points (rephrased; no abstract text copied)
  • Aim: improve DSSC performance by engineering dye molecular structure and electron-transfer characteristics.
  • Approach: synthesize a new phenothiazine-derived dye and evaluate it via spectroscopy/electrochemistry plus quantum-chemical calculations (e.g., DFT).
  • Key idea: non-planar dye geometries can help reduce aggregation and tune injection vs. recombination at the interface.
  • Why it matters: expands the design space for efficient metal-free sensitizers beyond conventional benchmark dyes.

2. Tuning the photo-characteristics of ZnO by coupling CdS/g-C3N4 for photodegradation and DSSC applications

  • Journal: Materials Research Bulletin (JIF 5.7)
  • Year: 2026
  • DOI: 10.1016/j.materresbull.2026.114095
    Key points (rephrased; no abstract text copied)
  • Aim: develop a multifunctional material useful for both photocatalytic water remediation and DSSC photoanodes.
  • Design: build a ternary ZnO/CdS/g-C3N4 composite to enhance visible-light harvesting and charge separation/transport.
  • Results: ~99.1% methylene-blue degradation (75 min) and DSSC performance of 2.23% PCE (Jsc 9.34 mA/cm², Voc 535 mV).
  • Impact: a relatively straightforward synthesis with a clear pathway to scalable, dual-use environmental and energy applications.

3. Synergistic co-sensitization of fluorene-and triphenylamine-derived thiazole dyes with N719: A quantum chemical and experimental investigation for enhanced DSSC performance

  • Journal: Arabian Journal of Chemistry (JIF 5.2)
  • Year: 2026
  • DOI: 10.25259/AJC_311_2025
    Key points (rephrased; no abstract text copied)
  • Problem: single dyes often have limited spectral coverage and can suffer from interfacial recombination.
  • Approach: co-sensitize newly designed thiazole-based organic dyes with N719 and use CDCA as a co-adsorbent to suppress dye aggregation.
  • Outcome: co-sensitization lifts PCE to ~7.9%, and adding CDCA raises it up to 9.93% (as reported in the files).
  • Why it matters: combining molecular design with interface engineering is a practical route to more efficient, stable, and lower-cost DSSCs.
