Herein, a-Si:H solar cells with different thickness of AZO spacer layer on nanodent plasmonic substrate are systematically investigated. Finite difference time domain (FDTD) simulation results demonstrate that the light absorption loss on the Ag surface is reduced as the AZO thickness increases, while the thicker AZO absorbs more light. In addition, solar …
In this report, we demonstrate that parasitic leakage currents dominate the current voltage characteristics of organic solar cells measured under illumination intensities less than one sun when the device shunt resistance is too low (<10 6 Ω cm 2).The implications of such effects on common interpretations of the light intensity dependence of the solar cell open …

A solar cell functions similarly to a junction diode, but its construction differs slightly from typical p-n junction diodes.A very thin layer of p-type semiconductor is grown on a relatively thicker n-type semiconductor.We then apply a few finer electrodes on the top of the p-type semiconductor layer.. These electrodes do not obstruct light to reach the thin p-type layer.
Non-geminate recombination is of relevance for any solar cell technology because it is the main factor that determines the open-circuit voltage1–6. In many thin-film solar cells, non-geminate recombination might also substantially affect charge collection and therefore the solar cell fill factor and short circuit current7–11. Thus ...

From Fig. 14, we can see that the current density of the solar cell improves as the thickness of the TiO 2 thin film increases. This may be attributed to the increase in the number and regularity of electrons and therefore the increase in crystal size [51] Now, we must realize that in the case of forward and reverse bias, the current of the TiO 2 /P-Si solar cell as …

In general, it is challenging to fabricate highly efficient semi-transparent solar cells which require a trade-off between efficiency and visible transparency of the whole devices [2].Actually, both of the characteristics depend on the perovskite thickness, for instance, thick active layer benefits to light absorption, film quality and thus photovoltaic performance, but …
