Abstract: An analytical expression relating the short-circuit current of an n-p silicon solar cell under AM0 illumination to the minority carrier diffusion length of the base region has been derived and compared with previous and new experimental data.
The short-circuit current is the current through the solar cell when the voltage across the solar cell is zero (i.e., when the solar cell is short circuited). Usually written as I SC, the short-circuit current is shown on the IV curve below. IV curve of a solar cell showing the short-circuit current.
The enhancement of the short circuit current density is mainly obtained due to the enhanced optical thickness of the solar cell. However, for the combination of a small period and a large height pyramid, poor charge extraction can be expected, which limits the short circuit current and energy conversion efficiency.
A solar cell generates the short-circuit current Isc = I E λ when exposed to radiation with spectral irradiance Eλ. The total irradiance is given by E = ∫0∞Eλdλ. In this study, we focus on the AM1.5 spectrum, so Eλ = EλAM1.5.
Since the solar cell does not utilize light of different wavelengths with the same efficiency, a better way to estimate the total increment on short-circuit current is to weight the result with the photon flux Ф n of the solar spectrum and the external quantum efficiency E Q E ( λ) of the used solar cell.
To determine the short-circuit current I STC of a solar cell, it must be (i) maintained at a temperature of 25 °C, (ii) irradiated with the global AM1.5 reference solar spectral irradiance distribution (AM1.5 spectrum), and (iii) under an irradiance of 1000 W/m 2. Highly accurate methods for determining the short-circuit current and linearity are in high demand.
Comparing the solar cell behavior in intensity-dependent and transient photocurrent measurements to the simulated behavior renders the hypotheses of a trap-induced space charge extremely unlikely and suggests a strong contribution of ionic motion to the observed current loss.

The performance of solar cells is determined by three factors: the open-circuit voltage (VOC), short-circuit current density (JSC), and fill factor (FF). The VOC and FF are determined by the material bandgap and the series/shunt resistance, respectively. However, JSC is determined by the amount of incident light in addition to the bandgap of the material. In this …

In organic solar cells, bimolecular recombination is a key factor limiting the device performance and creating the need for characterization. Light-intensity-dependent short-circuit current density measurements are a frequently used tool to qualitatively analyze bimolecular recombination in a device.
The short-circuit current, I sc, increases slightly with temperature since the bandgap energy, E G, decreases and more photons have enough energy to create e-h pairs. However, this is a small effect, and the temperature dependence of the short-circuit current from a silicon solar cell is typically; or 0.06% per °C for silicon.
