“…It can be noted that the series resistance also significantly influence the charge transport [50]. Since it is independent of bias voltage, we have selected impedance spectra of 1 V for the calculation of the resistance.…”

For the first time, an effort has been made to evaluate the charge transport properties of semiconducting natural rubber. Four different ratios of iodine-rubber composites are synthesised and tested for charge transport by current density-voltage characteristics (J-V) and impedance spectroscopy. The optimal doping ratio for best mobility value is identified, and the effect of injection barrier height on mobility is discussed. An attempt has also been made to correlate the density of states (DOS) with mobility and doping ratio. The transport properties of semiconducting natural rubber are compared with one of the most popular p-type material, Poly(3-hexylthiophene-2,5-diyl) (P3HT) under the same ambience and experimental conditions to demonstrate its potential as a cost-effective and green alternative organic semiconductor.

“…Alstrup et al [49] doped ZnO with Al in order to improve the conductivity and quality of the ZnO film deposited by the slot-die coating method. Lithium fluoride (LiF) has been used for a long time as an ultra-thin layer underlying the top Al electrode in standard configuration bulk heterojunction solar cells, since it improves device performances [56] and device stability [57]. Chang et al [58], on the contrary, used it for doping a sol-gel-derived ZnO ETL to be used in ISCs based on a P3HT:PCBM active blend, demonstrating an improvement of the overall PCE of the device from 2.9% to 3.3%.…”

Bulk heterojunction polymer solar cells (BHJ PSCs) are very promising organic-based devices for low-cost solar energy conversion, compatible with roll-to-roll or general printing methods for mass production. Nevertheless, to date, many issues should still be addressed, one of these being the poor stability in ambient conditions. One elegant way to overcome such an issue is the so-called "inverted" BHJ PSC, a device geometry in which the charge collection is reverted in comparison with the standard geometry device, i.e., the electrons are collected by the bottom electrode and the holes by the top electrode (in contact with air). This reverted geometry allows one to use a high work function top metal electrode, like silver or gold (thus avoiding its fast oxidation and degradation), and eliminates the need of a polymeric hole transport layer, typically of an acidic nature, on top of the transparent metal oxide bottom electrode. Moreover, this geometry is fully compatible with standard roll-to-roll manufacturing in air and is less demanding for a good post-production encapsulation process. To date, the external power conversion efficiencies of the inverted devices are generally comparable to their standard analogues, once both the electron transport layer and the hole transport layer are fully optimized for the particular device. Here, the most recent results on this particular optimization process will be reviewed, and a general outlook regarding the inverted BHJ PSC will be depicted.

“…The circuit used to model I-V curves includes two diodes in forward and reverse bias together with two parallel resistances. The parallel of the reverse bias diode and its corresponding resistance models the electrical behaviour of the interlayer and photoconductivity are presented [31,32,33]. There are numerous studies that develop the mathematical modeling of photovoltaic cells and verified by software: Matlab ; 1D Amps, PC1D, matrix transfert scaps-1D and General Purpose Photovoltaic Device Model (GPVDM).…”

Polymer solar cells have attracted much attention during the last years due to their lowerfabrication cost and possibility of using flexible substrates. Various parameters contribute to the stability of theperformances of organic solar cells: the configuration or the structure of the cells, the materials used in theirelaboration such as the active layer, the hole transport layer, the electron transport layer and the electrodecontact. This work represents the modelling and simulation of organic solar cells using two software: QuiteUniversal Circuit Simulator, QUCS and General-Purpose Photovoltaic Device Model, GPVDM. First, anequivalent circuit model constituted from one diode, a series and shunt resistance, and a photocurrent generatorhave been used, this circuit is simulated under QUCS. The simulated results as function of different parameterssuch as series resistance, temperature of the cell, the ideality factor and current saturation are given. Thecurrent density as function of voltage J-V characteristics of the organic cell obtained from the experimentalresults are compared to the simulated one, results show that the curve with Rs=10Ω correspond to theexperimental one, the ideality factor obtained by simulation of the organic cell is 1.2, which corresponds torecombination assisted by the traps levels. Second, we discuss the different structures of organic solar cells andthe role of the interface layer used as hole transport layer or electron transport layer. The effect of the thicknessand the type of the interfacial layers is simulated under GPVDM. The best efficiency is obtained in the case ofcell using aluminum-doped zinc oxide (AZO) as electron transport layer and copper oxide (Cu2O) as holetransport layer. The optimized cell is of the type: ITO/AZO (40 nm)/P3HT:PCBM (200 nm)/Cu2O (20 nm)/Ag,with a best power conversion efficiency of 5%.
