⏳ RUNNING - Simulation with tuned recombination parameters

Started: 2026-01-07 19:09:58
Elapsed: ~13 minutes
Expected: 15-20 minutes total (slower due to increased recombination)

# database.py - Silicon
'TAUN0': 0.1E-6,  # 100 ns
'TAUP0': 0.1E-6,  # 100 ns

Result: Simulated current ~143x too high

# database.py - Silicon  
'TAUN0': 1.0E-9,  # 1 ns (100x reduction)
'TAUP0': 1.0E-9,  # 1 ns (100x reduction)

Expected: Simulated current should match experimental within ~2-10x

Physics:

• Shorter carrier lifetime → more recombination
• Shorter diffusion length (L ∝ √τ)
• Lower saturation current density Js
• Current reduces by factor of √(τ_old/τ_new) ≈ √100 ≈ 10x

Expected Results:

The voltage-dependent error suggests we still need series resistance modeling (Rs ≈ 5Ω from experimental data).

1. ✅ Wait for simulation to complete
2. Check validation metrics (R², MAPE)
3. If needed: Add series resistance correction
4. Generate final comparison plots
