Solar cell devices physics

For example, metal workfunctions measured by photoelectron spectroscopy might be subject to change when an organic material is deposited on top, due to chemical reactions at the interface [ 8 ]. There are numerous experimental techniques available to study electrical material and device parameters of solar cells. In this review, we aim to give an overview of some of the most prominent experimental techniques.

We use numerical simulation to explain and quantify the effects that are observed in each of these measurements. To obtain quantitative solar cell and material parameters, the combination of several experimental techniques with numerical simulation is required [ 9 ]. The numerical simulation is fitted to the experimental results.

We reproduce nine experimental techniques with one set of parameters. We aim to provide a guide for the interpretation of experimental results. These experiments help to gain qualitative understanding of the underlying physical processes. While in the following we focus on organic solar cells, the characterization techniques discussed here are not restricted to them but can also be applied to other devices as quantum dots or perovskite solar cells.

Case study In order to explain the various effects to be observed in the different experimental techniques we first define 11 cases of solar cells each corresponding to a specific loss mechanism. Figure 1. Full simulation parameters of all cases are listed in the supplemental information SI. Table 1. Definition of 11 cases of solar cells. Case Description Base This is the standard single-layer device without charge traps or doping.

All other devices are derived from this base device. The detailed set of parameters can be found in the supplemental information SI. Extraction barrier This device features an extraction barrier for electrons.

Such a barrier can occur if an oxide layer forms at the electrode. Non-aligned contact This device has an injection barrier for electrons of 0. This is the case if the workfunction of the metal is too high to match the LUMO level of the active material [ 12 ]. High Langevin recombination The active material has a Langevin recombination efficiency that is 10 times larger than for the base device. The Langevin recombination efficiency depends on the material and on the morphology of bulk-heterojunction solar cells [ 5 ].

Phase segregation for example can lead to a lower recombination pre-factor [ 13 ]. In organic solar cells the trap density can depend on material purity [ 14 ]. Shunt resistances can occur due to non-uniformity of the film, particle contaminations, spikes of the ITO leading to short-circuits, pinholes or others [ 16 ].

For simplicity Ohmic shunting is used here. A high series resistance can be caused by the low lateral conductivity of the transparent electrode [ 18 ]. Unintentional doping can occur due to impurities that ionize.

Very deep traps can have the same effect. Photo-oxidation of single molecules during degradation can also lead to doping [ 19 ]. The physical origin can be reduced light absorption or hindered exciton dissociation. Physics of electroluminescence devices.

Another option is flow-battery based on vanadium penta-oxide Battery-integrated PV For a large positive VG we find resistive n—n behavior, whereas for an appropriate choice of VG an atomically thin p—n junction is formed and the device current I as a function of external bias voltage V displays diode-like rectification behavior inset in Fig.
