Optimized ST-OSC Architecture via DQL
The DQL algorithm successfully identified an optimal ST-OSC architecture with a MgF₂/Ag/ZnO bottom contact and MoO₃/Ag/WO₃ top contact, combined with a PBDB-T:ITIC active layer. Key material thicknesses were optimized for maximum Jph (31.5763 mA cm⁻²) and minimum AVT (25.2025%). This balance was achieved by precisely tuning layers like the MgF₂ anti-reflective layer (70 nm) and the active layer (93 nm), demonstrating DQL's capability to learn complex optical and electrical dynamics.
Key Takeaways:
- ✓ DQL effectively balances transparency and photon harvesting for ST-OSCs.
- ✓ Precise tuning of layer thicknesses is crucial for enhanced performance.
- ✓ Asymmetric DMD contact systems are highly functional for inverted ST-OSCs.
- ✓ AI-driven design reduces development time and computational cost significantly.
