Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
The solution process may enable anion doping by mixing anion solution with CuI-alkanolamine precursor solution, providing a route to valence-band-tunable CuI thin films.
Caveat: Stated as a forward-looking implication; this paper does not report doped-film synthesis or measurements.
7 · 3.5 Physical properties of CuI thin films
Void-and-crack-free CuI(1A2P) films on FTO are proposed as p-type semiconductor hole-transfer layers for reverse-layer or p-i-n perovskite solar cells.
Caveat: No solar-cell device performance is reported in the main article.
8 · Conclusion · Linked to 3 structured results
2AE and 2AM1P alkanolamine precursors are less desirable than 1A2P: 2AE crystallises temporarily and deteriorates film quality, while 2AM1P does not decompose to CuI at 150 deg C.
Caveat: The main text contains an apparent typo '2AE1P' in one paragraph; the conclusion clarifies 2AM1P.
7 · Conclusion · Linked to 3 structured results
CuI-1A2P is suitable for void-and-crack-free CuI thin films because the precursor has moderate crystallisation and thermal stabilisation, continuously melts, and decomposes between 100 and 130 deg C without a highly crystalline precursor state.
Caveat: Supporting thermal and XRD traces are in the SI; main text directly states the mechanism.
7 · Conclusion · Linked to 5 structured results
The CuI(1A2P) film has high carrier density for a solution-processed CuI film but modest mobility because low crystallinity and small grains inhibit carrier transfer at grain interiors and boundaries.
Caveat: Comparison depends on literature data in Fig. 7 and not all raw values are first-hand measurements in this paper.
