Non‐Fullerene Organic Electron Transport Materials toward Stable and Efficient Inverted Perovskite Photovoltaics

Small, Год журнала: 2024, Номер 20(43)

Опубликована: Июнь 26, 2024

Inverted perovskite solar cells (PSCs) attract continuing interest due to their low processing temperature, suppressed hysteresis, and compatibility with tandem cells. Considerable progress has been made reported power conversion efficiency (PCE) surpassing 26%. Electron transport Materials (ETMs) play a critical role in achieving high-performance PSCs because they not only govern electron extraction from the layer cathode, but also protect contact ambient environment. On other hand, non-radiative recombination losses at perovskite/ETM interface limits future development of PSCs. Compared fullerene derivatives, non-fullerene n-type organic semiconductors feature advantages like molecular structure diversity, adjustable energy level, easy modification. Herein, ETM is systematically summarized based on functionalization strategy. Various types design approaches for producing are presented, insight relationship chemical device performance discussed. Meantime, trend analyzed. It hoped that this review provides insightful perspective innovation new ETMs toward more efficient stable

Hybrid organic–inorganic perovskite solar cells (PSCs) have shown significant potential in photovoltaic applications due to their superior optoelectronic properties. However, the conventional electron transport layer (ETL) of C60 PSCs poses challenges such as incomplete coverage and metal diffusion, leading reduced performance stability. This work explores efficacy atomic deposition (ALD) SnO2 an interlayer between electrode enhance stability devices. Devices with varying thicknesses were fabricated, revealing that a 15 nm ALD-SnO2 optimally improved power conversion efficiency (PCE) 23.85%, compared 22.86% achieved BCP layer. Moreover, SnO2-based devices exhibited open-circuit voltage (VOC), short-circuit current density (JSC), fill factor (FF). Modules (30 × 30 cm) demonstrated notable enhancements uniformity, suggesting for scalable commercial applications. Photoluminescence (PL) electrochemical impedance spectroscopy (EIS) analyses confirmed charge extraction recombination buffer research indicates is promising candidate PSCs, providing pathway toward higher technology.
