Hybrid lead halide perovskite solar cells (PSCs) in tandem application with copper indium gallium diselenide (CIGS) solar cells represent one of the most promising all-thin-film technologies for next-generation photovoltaic devices.

In a solar cell structure, all the supporting layers and scattering elements additional to the photovoltaic material are sources of parasitic absorption, meaning that part of the incident sunlight absorbed by the device does not contribute to the obtainable photocurrent.
Conclusions In this work we extended the analytical light-trapping model by Basore to account for parasitic absorption in the skins via the lumped parasitic absorption parameter Appp, specifically for the near-infrared (NIR)/red response of a solar cell. As the original model, the model of this work is applicable to wafer-based Si solar cells.
Parasitic absorption refers to an optical absorption mechanism that does not lead to the creation of an electron hole pair in the silicon bulk. Fig. 4 below illustrates the sources of optical losses in a solar cell, encompassing incident light that fails to generate an electron-hole pair.
In addition, particularly for plasmonic-based light trapping, the trade-off between the beneficial effects of scattering and the deteriorating effects of parasitic absorption can severely limit the overall photocurrent enhancement that can be produced in solar cells 20, 21, 22.
The impact of unwanted parasitic losses in the metal must be weighed against potential cell performance enhancements these structures can provide 23. Some studies tended to consider absorption in the solar cell, while neglecting absorption in the metal.
Via idealized solar cell simulations assuming a full-area back side skin with parasitic absorption, we determine a rule-of-thumb threshold for Appp of approx. 1%, below which parasitic absorption has no significant impact on generated current density and thus efficiency.

Nevertheless, parasitic absorption should always be carefully determined computationally and/or in experiments when reporting on absorption enhancement. An elegant way to avoid parasitic absorption through field enhancement in scattering structures is the texturing of the absorbing silicon itself. In this case, the light absorption occurs ...
Abstract: The current losses due to parasitic absorption in the indium tin oxide (ITO) and amorphous silicon (a-Si:H) layers at the front of silicon heterojunction solar cells are isolated and quantified.

Effective surface passivation is crucial for improving the performance of crystalline silicon solar cells. Wang et al. develop a sulfurization strategy that reduces the interfacial states and induces a surface electrical field at the same time. The approach significantly enhances the hole selectivity and, thus, the performance of solar cells.

Parasitic absorption refers to the absorption of light in non-active layers or materials within a solar cell that is not intended for efficient charge generation. Transparent conductive layers, contact layers, antireflection coatings, and passivation layers can all contribute to parasitic absorption losses (Fell et al., 2022). While ...
In the past years, CSCs based on transition metal oxides (TMOs) have been extensively investigated in c-Si solar cells, because they have a wide band gap (typically above 3 eV) to reduce parasitic absorption and are easy to deposit using a variety of cost-effective methods, such as thermal evaporation, spin coating, and atomic layer deposition. 6–10 In the …

In high-efficiency CdTe solar cells, the parasitic absorption in the CdS layer is also reduced by adopting a thin layer [77, 78], as mentioned earlier. For CIGSe solar cells, to suppress the J sc loss induced by the CdS layer, a Zn(O,S) layer has also been applied . In the CIGSe and CZTSSe-based solar cells, a strong optical loss also occurs by the parasitic …
