After completion of the solar cell manufacturing process the current–density versus voltage curves ( J ( U) curves) are measured to determine the solar cell's efficiency and the mechanisms limiting the efficiency. An accurate and robust analysis of the measured curves is essential.
Photovoltaic cells (PV) are tools used for the effective and sustainable conversion of the abundant and radiant light energy from the sun into electrical energy [4, 5, 6, 7, 8]. In its basic form, a PV is an interconnection of multiple solar cells aimed at achieving maximum energy output (see Figure 1).
Solar photovoltaic (PV) have nonlinear voltage-current characteristics, with a distinct maximum power point (MPP) depending on factors such as solar irradiance and operating temperature. To extract maximu...
However, an extensive analysis of the accuracy of the reconstructed curves for different PV models at the maximum power point (MPP) has not been conducted at the time of writing this paper. The IEC EN 50530 standard stipulates that the absolute errors within the vicinity of MPP should always be less than or equal to 1%.
It therefore serves as an optimal starting point to analyse performance losses of solar cells. Current density–voltage characteristics (J–V s) are widely acknowledged as the cornerstone measurement in solar cell (SC) research since they allow for the quantification of a SC's power conversion efficiency (PCE).
The PV characteristic curve, which is widely known as the I–V curve, is the representation of the electrical behavior describing a solar cell, PV module, PV panel, or an array under different ambient conditions, which are usually provided in a typical manufacturer’s datasheet.
Potential-induced degradation in perovskite/silicon tandem photovoltaic …
Applying a −1,000 V voltage bias to perovskite/silicon tandem PV modules for 1 day causes potential induced degradation with a ∼50% PCE loss, which raises concerns for tandem commercialization. During such testing, Xu et al. observe no obvious shunt in silicon subcells but degradation in perovskite subcells caused by the diffusion of the elements.

Strain-gradient-induced modulation of photovoltaic efficiency
This paper shows that the flexophotovoltaic effect can modify the photovoltaic efficiency of perovskite solar cells. We find that not only do strain gradients have a quantitatively large impact on the total efficiency, but the effect can be either positive (efficiency enhancement) or negative (efficiency decrease) depending on the relative signs of the strain gradient and the …
