研究目的
Exploring the insights into the device physics of perovskite solar cells gained from modeling and simulation, focusing on factors like ions, dielectric constant, density of states, and recombination losses.
研究成果
The simulations reveal that perovskite solar cells can form a self-induced dipole at interfaces, significantly enhancing the built-in potential and open-circuit voltage, especially in cases of non-ideal energetic alignment. The study concludes that device modeling is a powerful tool for understanding and optimizing perovskite solar cells, but also points out the need for further research to address open questions in the field.
研究不足
The study acknowledges the complexity of including ions in simulations and the challenges in accurately modeling transient phenomena and hysteresis effects. It also highlights the need for further investigation into the role of grain boundaries and the impact of interfacial engineering on device performance.
