Author interpretations and caveats

Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.

Application RelevanceSupport assessment: High

The 4 mg mL-1 In10 loading optimises the balance between improved conductivity/charge extraction and morphology; 6 mg mL-1 causes agglomeration and poorer device performance.

Caveat: Cross-sectional SEM and numerical EIS values are available from rendered SI, but Fig. S5 CV curve body remains unavailable locally.

CaveatSupport assessment: High

Rendered SI pages resolve the previously missing Table S1 crystal data and Table S2 EIS numerical values, but the Figure S5 CV plot body is not visible in the local rendered/text layer.

Caveat: Do not extract HTM/HTM-In10 CV curve values from Figure S5 until a complete source figure or raw data file is available.

Composite RoleSupport assessment: Medium

In10 improves PSC light response through UV absorption, visible photoluminescence and enhanced scattering, contributing to improved IPCE and SPS response.

Caveat: The optical mechanism is supported by spectra and trends but not isolated quantitatively from conductivity effects.

Structure Property LinkSupport assessment: Medium

The In10 and Spiro-OMeTAD frontier levels are well aligned, with no large HOMO barrier, supporting incorporation of In10 into the hole transport material.

Caveat: Energy levels are reported/calculated, but direct charge mobility or absolute conductivity of In10 is not measured.

Transport MechanismSupport assessment: High

In10 oxidises Spiro-OMeTAD to Spiro-OMeTAD+, causing the 520 nm absorption increase and improving hole-transport-layer conductivity.

Caveat: No absolute conductivity value or independent Spiro-OMeTAD+ concentration is reported.
