Perovskite solar cells (PSCs) have achieved unprecedented power conversion efficiencies (PCEs) in a remarkably short time, with certified PCEs now exceeding 26.1% for single-junction devices and 33.7% for perovskite-silicon tandem cells, as reported in 2023. This rapid progress is attributed to the unique optoelectronic properties of perovskites, such as high absorption coefficients (>10^4 cm^-1), tunable bandgaps (1.2–2.3 eV), and long carrier diffusion lengths (>1 µm). Recent advances in compositional engineering, such as the incorporation of formamidinium (FA) and cesium (Cs) cations with reduced bromine content, have significantly improved stability under operational conditions, achieving >1,000 hours of continuous illumination at 85°C without significant degradation.
The development of low-dimensional perovskites has emerged as a promising strategy to enhance both efficiency and stability. By introducing bulky organic cations like phenylethylammonium (PEA) or butylammonium (BA), researchers have created quasi-2D perovskite structures that exhibit improved moisture resistance while maintaining high PCEs (>22%). These materials also demonstrate reduced ion migration, a critical factor in long-term stability. Recent studies have shown that optimized 2D/3D heterostructures can achieve PCEs of 24.5% with <5% efficiency loss after 1,000 hours of maximum power point tracking under full sunlight.
Scalability and manufacturing compatibility are critical for the commercialization of perovskite photovoltaics. Slot-die coating and blade-coating techniques have enabled the fabrication of large-area modules (>800 cm²) with PCEs exceeding 18%. In 2023, a team demonstrated a roll-to-roll printed perovskite module with a PCE of 17.3% on a flexible substrate, showcasing the potential for lightweight and portable applications. Additionally, advancements in ink formulations and crystallization control have reduced processing temperatures to <100°C, enabling integration with low-cost substrates like PET and PEN.
The environmental impact of perovskite materials has been addressed through the development of lead-free alternatives. Tin-based perovskites, such as CsSnI3 and MASnI3, have achieved PCEs up to 14.6%, while double perovskites like Cs2AgBiBr6 show promise with PCEs of 8.5%. However, challenges remain in improving their stability and reducing defect densities. Recent breakthroughs in passivation strategies using organic molecules like ethylenediammonium diiodide (EDAI2) have extended the operational lifetime of tin-based devices to >500 hours under ambient conditions.
Integration of perovskites into tandem architectures has unlocked new frontiers in photovoltaic performance. Perovskite-silicon tandems have reached record PCEs of 33.7%, surpassing the theoretical limit of single-junction silicon cells (29.4%). Similarly, all-perovskite tandems combining wide-bandgap (~1.8 eV) and narrow-bandgap (~1.2 eV) subcells have achieved PCEs up to 28%. These advancements are driven by precise bandgap tuning via halide alloying and interfacial engineering using materials like SnO2 and PTAA to minimize optical losses (<0.5 mA/cm²). The potential for these technologies to achieve PCEs >35% is now within reach.
