Abstract Organic photovoltaics (PV) is an energy-harvesting technology that offers many advantages, such as flexibility, low weight and cost, well environmentally benign materials manufacturing techniques. Despite growth of power conversion efficiencies to around 19 % in the last years, organic PVs still lag behind inorganic PV technologies, mainly due high losses open-circuit voltage. Understa...

The power conversion efficiency of solar cells strongly depends on the open-circuit voltage which, in turn, recombination activity within device. A possible source detrimental charge carrier is band tails. An empirical linear relationship between loss and Urbach energy tails has been shown past. Here we discuss how influence radiative nonradiative bulk absorber. First, show through photolumines...

The trade-off between the short-circuit current density (JSC) and open-circuit voltage (VOC) has been one of largest challenges in improving power conversion efficiencies (PCEs) organic solar cells...

In recent years, lithium-ion batteries (LiBs) have gained a lot of importance due to the increasing use renewable energy sources and electric vehicles. To ensure that work properly limit their degradation, battery management system needs accurate models capable precisely predicting parameters. Among them, state charge (SOC) estimation is one most important, as it enables prediction battery’s av...
