چکیده
• Thermal annealing of Cu 2 ZnSnS 4 solar cell in air improved the characteristics. The band gap decreased with thermal air. Cd diffusion was observed from CdS to . Increase external quantum efficiency hot-plate annealing. In this work, a detailed study effect treatment (hot plate) on Mo/CZTS/CdS/i-ZnO/ITO carried out, which promotes contained window layer towards absorber CZTS. out at temperatures ranging 100 °C 400 and times varying 3 15 min atmosphere. CZTS grown deposits metallic precursors (Cu/Sn/Cu/Zn) by sputtering two ramps: 200° C for 45 an argon flow 1 mbar 550 5 bar atmosphere S + Sn. For complete cells hotplate 280 6 increase 2.7% 5.2% conversion compared without treatment. 1.56 1.43 eV Jsc increased 12.0 mA/cm 15.4

متن کاملThe Effect of Rapid Thermal Annealing on InAs/GaAs Quantum Dot Solar Cells
The effect of post-growth annealing on InAs/GaAs quantum dot solar cells (QDSCs) has been studied. A significant improvement in photoemission, photocurrent density, and spectral response has been observed with post-growth annealing. The optimal anneal temperature was found to be 700 ° C, which lead to an 18% improvement in current density from 4.9 mA cm -2 for as-grown sample to 5.8 mA cm -2 . ...
