Herein, a strong short-circuit current density (J SC) loss is observed when using phenetylammonium iodide (PEAI) as n-side passivation in p–i–n perovskite solar cells paring experiments with drift–diffusion simulations, different hypotheses for the origin of the J SC loss are presented and evaluated. ...

The voltage drop ΔU caused by lateral currents increases with illumination and leads to an artificially increased pFF. ... and the light-generated current, IL, of a solar cell are determined ...
Perovskite solar cells in p–i–n architecture passivated with a PEAI-based 2D perovskite show a strong short-circuit current loss with a simultaneous increase in V …
Design and Demonstration of High-Efficiency Quantum ...
Increasing the open-circuit voltage (Voc) is one of the key strategies for further improvement of the efficiency of perovskite solar cells. It requires fundamental understanding of the complex optoelectronic processes related to charge carrier generation, transport, extraction, and their loss mechanisms inside a device upon illumination. Herein, …

Photovoltaic Solar Cells: A Review
For most solar cell measurement, the spectrum is standardised to the AM1.5 spectrum; the optical properties (absorption and reflection) of the solar cell …
A 15.7% power conversion efficiency of CsPbI3 solar cells is achieved, which is the highest efficiency reported for inorganic perovskite solar cells up to now. And more importantly, the devices can tolerate continuous light soaking for more than 500 h without efficiency drop.
Series Resistance
The use of a mixed solvent of γ-butyrolactone and dimethylsulfoxide (DMSO) followed by toluene drop-casting leads to extremely uniform and dense perovskite layers via a CH3NH3I-PbI2 …
If your global solar cell was not very uniform (rather likely for many solar cell types), your local solar cells may show wildly different behaviour. The IV characteristics of the, let''s say, 8 local cells that contain serious shunts (=short circuits) will be far more affected by this than your global cell (where you have another 9 992 shunt-free cells switched in parallel).
Series resistance losses are known to affect the cell efficiency through a drop in the Fill-Factor (FF), which amplitude is a function of the cell architecture used, …

An equivalent circuit model of an ideal solar cell''s p–n junction uses an ideal current source (whose photogenerated current increases with light intensity) in parallel with a diode (whose current represents recombination losses). To account for resistive losses, a shunt resistance and a series resistance are added as lumped elements. The resulting output current equals the photogenerated curr…
The dramatic drop in the cost of solar photovoltaic (PV) modules, which has fallen by 99 percent over the last four decades, is often touted as a major success story for renewable energy technology. ...
