1. Performance advantages
A. High efficiency: The single-junction laboratory efficiency can reach 26.1%, and the tandem (such as perovskite/silicon) efficiency exceeds 33.9%.
B. Low cost: Less material is used (the film thickness is only at the micrometer level), and the low-temperature process reduces energy consumption.
C. Lightweight and flexible: It weighs only 1/10 of crystalline silicon modules and is bable (with a radius of curvature < 5mm), suitable for building integration (BIPV) and wearable devices.
D. Low light response: Maintains a high output even under scattered light or indoor light.
2. Core Challenges
A. Stability issue:
a. Moisture, oxygen, light and thermal stress cause perovskite decomposition (such as the formation of PbI₂).
b. Ion migration causes phase separation or electrode corrosion.
c. Lead toxicity: Lead-free materials (such as Sn²⁺, Bi³⁺ -based perovskites) or encapsulation and recycling technologies need to be developed.
B. Large-area uniformity: Efficiency loss when components are scaled up (such as the "efficiency scissors difference" from a 1 cm² battery to a module).
3. Application Prospects
A. Photovoltaic field:
a. Stacked cells: Combined with silicon cells, they break through the Shockley-Queisser limit.
b. Semi-transparent modules: used in smart Windows or agricultural photovoltaics.
B. Emerging Scenarios:
a. Flexible electronics (such as power supply for unmanned aerial vehicles, curved car roofs).
b. Indoor light energy collection (to power IoT devices).
Perovskite thin-film modules, with their outstanding photoelectric performance and process flexibility, are expected to revolutionize the traditional photovoltaic industry. Although stability and toxicity issues still need to be overcome, with the advancement of materials science and packaging technology, its commercialization process is accelerating and it may become an important part of clean energy in the future.
