Hybrid Perovskite Flexible Photovoltaic Solar Cell with Tandem / Multi-Junction Design Achieving 50%

Conventional silicon-based solar cells are rigid and heavy, limiting their use on curved surfaces or portable gear. They also suffer from the "single-junction efficiency limit," where high-energy photons lose energy as heat rather than generating electricity. While existing perovskite or organic cells are flexible, they often struggle with low efficiency and long-term stability.

The solution is a hybrid multi-junction cell that stacks perovskite and organic layers to optimize light absorption across the spectrum. It employs an advanced light management system with quantum dots and photonic crystals to trap photons and a thermoelectric layer to harvest thermal energy. This integrated approach, produced via roll-to-roll manufacturing, achieves record-breaking efficiency while maintaining flexibility and durability.

The invention addresses the "Shockley-Queisser limit" of single-junction cells, which prevents them from converting more than ~33% of sunlight. It also solves the common issue of performance degradation due to heat by integrating thermoelectric materials that turn waste heat back into electrical power.

The invention bridges the gap between high-efficiency (traditionally rigid) and flexibility (traditionally low-efficiency). It introduces a self-healing function and thermal energy harvesting into a single flexible platform, enabling high-power output in environments where traditional solar panels cannot be deployed.
