Summary
A new halide-diffusion-assisted lamination method improves semitransparent perovskite solar cells (PSCs). This technique enhances device performance and thermal stability, paving the way for efficient bifacial and tandem solar applications.
Area of Science:
- Materials Science
- Renewable Energy
- Photovoltaics
Background:
- Semitransparent perovskite solar cells (PSCs) offer potential for bifacial and tandem applications due to efficient light absorption.
- Current lamination methods for PSCs suffer from imperfect contact, leading to voids and perovskite degradation.
- High-performance laminated PSCs are crucial for advancing solar energy technologies.
Purpose of the Study:
- To develop an improved lamination method for semitransparent perovskite solar cells.
- To address challenges of void formation and perovskite degradation in laminated PSCs.
- To enhance the efficiency and stability of semitransparent PSCs.
Main Methods:
- A novel halide-diffusion-assisted lamination (HDL) method was developed.
- The HDL method utilizes a controlled halide concentration gradient for effective lamination of perovskite layers.
- Semitransparent PSCs were fabricated using the proposed HDL method.
Main Results:
- The developed HDL method successfully laminated perovskite layers, minimizing voids and degradation.
- HDL-processed PSCs achieved a power conversion efficiency (PCE) of 18.93%.
- HDL-PSCs demonstrated enhanced thermal stability, retaining initial PCE for over 1200 hours at 85°C.
Conclusions:
- The halide-diffusion-assisted lamination method is effective for fabricating high-performance semitransparent PSCs.
- The HDL method significantly improves the stability and efficiency of PSCs.
- This advancement holds promise for the commercial viability of perovskite solar technology.
