A Heterojunction Based on Macro-porous Silicon and Zinc Oxide for Solar Cell Application
Bibliographic record
Abstract
Transparent and conductive Al doped zinc oxide (AZO) films were reactively sputtered from metallic targets onto macro-porous silicon (MPS) substrate to fabricate a heterojunction interface structure. A tungsten oxide (WO3) thin film was placed between metallic aluminum back contact and bulk silicon to extract photogenerated holes from the absorber. Due to the susceptibility of PS to naturally oxidize over the period of time, a thin film of SiO2 was thermally grown to stabilize the electrical response of the junction. Such thin layer acts as passive film to prevent recombination and is placed between the p-n junction. Photovoltaic properties of this heterojunction were studied by using the current density-voltage (J-V) measurement under AM 1.5 illumination. The experimental results show an increase in photovoltaic performance of AZO/MPS solar cell with a buffer layers of WO3. Such heterostructures are promising for the development of the low-cost, clean, and durable devices with appreciable light-to-electricity conversion efficiency.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
