Exploring the optoelectronic and photovoltaic potential of Spiro-OMeTAD derivatives through quantum chemical investigations
Bibliographic record
Abstract
This study provides an extensive evaluation of nine hole transport materials (HTMs) for solid-state dye-sensitized solar cells (ssDSCs), utilizing time-dependent density functional theory (TD-DFT) with the B3LYP level and the 6-31G(d,p) basis set. We investigated their electronic, optical and charge transport properties. The performance parameters of a photovoltaic cell, such as light harvesting efficiency (LHE), short-circuit current density (JSC), and open-circuit voltage (VOC), were analyzed. All the studied molecules exhibit energy band gaps ranging from 2.994 eV to 3.541 eV, confirming their ability to absorb light in the visible range. In addition to optical properties, the study explores charge transfer integrals, transport rates and mobility of charge, emphasizing the importance of efficient hole and electrons mobility and reduced charge recombination. These findings highlight the potential of these molecules as leading candidates for enhancing the efficiency of ssDSCs.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
