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）
- 年：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。

2. Tuning the photo-characteristics of ZnO by coupling CdS/g-C3N4 for photodegradation and DSSC applications
- 掲載誌：Materials Research Bulletin（JIF 5.7）
- 年：2026
- DOI：10.1016/j.materresbull.2026.114095
ポイント（わかりやすい箇条書き） - 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。
- 結果：メチレンブルー分解99.1%（75分）など高い光触媒性能、DSSC光アノードとしてPCE 2.23%（Jsc 9.34 mA/cm², Voc 535 mV）を報告。
- 意味：合成が比較的シンプルで、環境浄化と発電を同じ材料設計思想で前進できる。

3. Synergistic co-sensitization of fluorene-and triphenylamine-derived thiazole dyes with N719: A quantum chemical and experimental investigation for enhanced DSSC performance
- 掲載誌：Arabian Journal of Chemistry（JIF 5.2）
- 年：2026
- 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.
