Upscaling Perovskite Photovoltaics: from 156 cm² Modules to 0.73 M² Panels

Area of Science:

• Materials Science
• Renewable Energy Engineering
• Photovoltaics

Background:

• Perovskite solar modules (PSMs) face challenges in upscaling for industrial applications.
• Achieving high power conversion efficiencies (PCEs) in large-area devices is crucial for commercial viability.

Purpose of the Study:

• To address the upscaling challenges of PSMs and achieve high PCEs.
• To optimize cell interconnection design for improved geometric fill factor (GFF).
• To demonstrate the feasibility of large-area perovskite solar panels (PSPs).

Main Methods:

• Systematic experimentation for PSM fabrication.
• Refinement of cell interconnection design.
• Fabrication and testing of large-area PSPs integrating optimized PSMs.

Main Results:

• A PCE of 17.68% was achieved for PSMs on a 15.6 cm × 15.6 cm substrate.
• An optimized cell interconnection design yielded a GFF of 96.4%.
• Successfully fabricated and tested large-area PSPs (0.73 m²) with integrated optimized PSMs.

Conclusions:

• The study demonstrates a significant advancement in the scalability of perovskite solar technology.
• The achieved PCE and GFF set new benchmarks for large-area perovskite photovoltaics.
• This work paves the way for practical application of perovskite solar technology in renewable energy generation.
