研究目的
To quantify the efficiency-determining processes in all-polymer solar cells and understand the impact of field-dependent charge separation on performance.
研究成果
Field-dependent charge separation limits the fill factor and thus the performance of all-polymer solar cells. The study successfully quantifies the efficiency-determining processes and demonstrates the utility of combining transient optical and electro-optical experiments with simulations to understand solar cell performance.
研究不足
The study focuses on a specific test system, and the findings may not be universally applicable to all all-polymer solar cells. The impact of field-dependent charge separation on performance is highlighted, but other factors may also play significant roles.
The study combines transient optical and electro-optical experiments to analyze the efficiency-determining processes in all-polymer solar cells. It involves the use of transient absorption spectroscopy, time-resolved photoluminescence, and time-delayed collection field experiments to quantify the yields of various photophysical processes. The experimental data is used to simulate current-voltage characteristics via drift-diffusion simulations to compare with experimentally measured values.
