The results show that the shunt resistance (R sh) can affect the FF, and the PSC with higher R sh exhibit better performances under weak light. Because of the effects of weak diode leakage mechanism in the cell, the performances of PSC with low R sh would deteriorate dramatically with the decrease of light intensity.

Weak light behavior of solar cells: rel. low light efficiency vs. dark forward current I dark at +0,5V. The graph show a good correlation and the theoretical 1- diode-model approach. ...
The weak light performance of multi- and mono-crystalline PV modules are known to be dependent on the used cell type, but also vary from cell supplier to cell supplier using even the same cell type . It is shown, that this is a result from the characteristic distribution of the parasitic resistances. This paper shows that these differences can lead to 10% difference …

We investigated the variation of current density–voltage (J–V) characteristics of an organic solar cell (OSC) in the dark and at 9 different light intensities ranging from 0.01 to 1 sun of the ...
However, most of the solar cells are not perfect energy harvesters under low light conditions due to the weakness of being a minority carrier device. Dye-sensitized Solar Cell (DSC), one of the emerging photovoltaic (PV) techniques, has several advantages such as being colorful, flexible, and having a relatively low fabrication cost.
Due to their excellent photo-to-electric power conversion efficiency (PCE) (up to 25.2%) under AM 1.5G (≈100,000 Lux), the perovskite solar cells (PSCs) have …
To get access to PV characteristics at indoor light levels as well as the specific spectral response (SR) characteristics, a cell survey has been carried out. In this paper the …
The OPV cells show increased exciton dissociation probability under weak light. • The OPV cells show longer carrier lifetime under weak light. • The increased extrinsic/intrinsic series resistance affects the PV parameters …
Pectin, a component of the plant cell wall, is involved in cell adhesion and environmental adaptations. We generated OsPG-FOX rice lines with little pectin due to overexpression of the gene encoding a pectin-degrading enzyme [polygalacturonase (PG)]. Overexpression of OsPG2 in rice under weak light …
