“…An example of promising OSCs, is a blend of the fullerene derivative [6,6]-phenyl-C61 butyric acid methyl ester (PCBM) and regioregular poly (3-hexylthiophene) (P3HT) heterojunction, which has been experimentally studied earlier [24]. A phase-separated bulk heterojunction (BHJ) nanostructure of large interfacial area is formed from this blend [25]. A thin poly (3, 4-ethylenedionythiophene): poly (styrenesulfonate) (PEDOT:PSS) layer is used as an anode contact because the work function of PEDOT:PSS matches with the HOMO of P3HT and this allows for effective extraction of holes from the active layer [26].…”

In this work, a newly fabricated organic solar cell based on a composite of fullerene derivative [6,6]-phenyl-C61 butyric acid methyl ester (PCBM) and regioregular poly (3-hexylthiophene) (P3HT) with an added interfacial layer of AgOx in between the PEDOT:PSS layer and the ITO layer is investigated and an equivalent circuit model is proposed for the device. Incorporation of the AgOx interfacial layer shows an increase in fill factor (by 33%) and power conversion efficiency (by 28%). Moreover, proper correlation has been achieved between the experimental and simulated I-V plots. The simulation shows that device characteristics can be explained with accuracy by the proposed model.

“…Carbon-based semiconductors exhibit desirable light absorption and charge creation properties with the capability of manufacturing by low-temperature processes [1][2][3]. According to the type of materials used in their structure, excitonic solar cells are classified into two main categories: dye-sensitized solar cells (DSC) [4] and organic solar cells (OSC) [5] developed in single layers [6] and bi-layers [7] including planar [8] and bulk heterojunction configurations [9]. A schematic view of different excitonic solar cells is shown in Figure 1.…”

While improving the performance of excitonic solar cells (XSCs) has been a central effort of the scientific community for many years, theoretical approaches facilitating the understanding of electron-hole interaction, recombination and electron-phonon coupling effects on the cell performance are still needed. We present a novel simple model which is based on the quantum scattering theory, in particular on the Lippmann-Schwinger equation; this minimizes the complexity of the problem while providing useful and nontrivial insight into the mechanism governing photocell operation. In this formalism, both exciton pair creation and dissociation are treated in the energy domain, and therefore there is access to detailed spectral information, which can be used as a framework to interpret the charge separation yield. Our analysis helps to optimize the charge separation process and the energy transfer in excitonic solar cells.
