PTQ10/T2EH blend is more accessible to achieve charge separation by direct photoexcitation. The application of a strong external electric field (Fext) facilitates the control of light-induced charge transfer and photovoltaic performance.
Based on Marcus theory, the photoinduced electron transfer properties of D-A type non-fullerene acceptor organic solar cells (OSCs) under the dependence of external electric field (Fext) were investigated. The research results shown that the charge transfer mode under different Fext intensities changes with certain regularity.

In this article, we studied the influence of an external electric field applied in the base of a solar cell on its various electric parameters when it is illuminated by a monochromatic light. We have taken into account the actual values of intrinsic recombination velocities at the junction and the back face. This study revealed that when the
This study deals with external electric field influence on polycrystalline silicon solar cell behavior. We study an n-p-p + solar cell under electric field resulting from a polarization and under constant multispectral illumination. Taking into account this electric field, we establish news expressions of continuity equation, photocurrent density and back surface recombination velocity.
Here, we demonstrate a unique nonchemical approach that employs an external electric field (EEF) to tune the morphology of photoactive layers in the wet coating process (not after the film is already dried). This method is highly effective in improving the BHJ morphology and device performance over a number of SMA-based OSC systems, showing its
Here, we demonstrate a completely different approach by applying an external electric field (EEF) on the active layer during the wet coating. The EEF-coating method is perfectly compatible with an ambient blade coating using environmentally friendly solvents, which are essential requirements for industrial production of OSCs. A

The shielding electric field will enhance the local polarization in quasi-2D perovskite solar cells, leading to the directional movement of ions under the action of the external electric field. Due to the shielding effect of the electric field, the charge carrier diffusion at the interface will weaken or even disappear, and the shielding electric field generated will also

When the solar cell is unconnected (or the external electrical load is very high) the electrons and holes will ultimately restore equilibrium by diffusing back across the junction against the field and recombine with each other giving off heat, but if the load is small enough then it is easier for equilibrium to be restored by the excess electrons going around the external circuit, doing
