What causes shunt resistance in a solar cell?
Shunt resistance (R s h) is created due to leakage currents produced at the edge of the f-PSCs and the imperfection of the cell structure . This affects the parallel conductivity of a solar cell depending on the cell junction [, , , ]. As leakage currents increase, the efficiency of any solar cell decreases.
Why are third-generation solar cells more demanding than silicon solar cells?
Developing a physical understanding of mechanisms governing the operation of third-generation solar cells is much more demanding than for silicon solar cells. Crystalline silicon solar cells are doped and thicker than 100 μm. Both factors combined lead to the screening of the electric field such that the largest part of the device is field-free.
What are perovskite-based solar cells?
Perovskite-based solar cells (PSCs) represent a remarkable advancement in the field of solar energy because of their low cost and high absorption coefficient.

Can 1/c 2/3 be used to analyze organic solar cells?
Tripathi and Mohapatra proposed to use the relation 1/C 2/3 for the analysis of organic devices [ 93 ]. Their analysis is however based on the assumption of a unipolar device and is therefore also not suited for the analysis of solar cells. We propose to use dark-CELIV to estimate the lower limit of the doping density of organic solar cells.
Why is photocurrent J Ph a problem in organic solar cells?
In organic solar cells, the photocurrent j ph can depend on the voltage due to Onsager-Braun dissociation of excitons into free carriers [ 38 ]. In devices with field-dependent charge generation, the analysis of the light ideality factor might be prone to errors [ 39 ].
