“…Figure 4(a) also displays the J-V curve of the rear subcell. As expected, the photovoltage was increased to 0.83 V, which was larger than that of a typical P3HT:PC 60 BM-based device (i.e., 0.59V) [11], due to the higher LUMO energy of ICBA [23]. Further, The values of J sc and FF were 10.21 mA cm −2 , and 0.62, respectively; the calculated PCE was 5.24%.…”

“…Organic photovoltaic devices (OPVs) hold great promise for next-generation solar cells because of their advantageous properties including inexpensive fabrication, mechanical flexibility, light weight and short energy pay-back times [6][7][8][9]. The unique material properties of OPVs enable a wide range of potential applications, including energy resources for outer space and biomedical treatments [10,11]. However, further efforts will be still required to improve their efficiencies for practical applications.…”

This paper describes a promising approach toward preparing effective electrical and optical interconnections for tandem organic photovoltaic devices (OPVs). The first subcell featured a semi-transparent electrode, which allowed a portion of the solar irradiation to pass through and to enter the second subcell exhibiting complementary absorption behavior. The resulting multi-junction OPV had multiple contacts such that the subcells could be easily connected either in series or in parallel. More importantly, we used UV-curable epoxy to "mechanically" stack the two subcells and to eliminate the air gap between them, thereby reducing the optical loss induced by mismatches of refractive indices. Therefore, an improved power conversion efficiency of approximately 6.5% has been achieved.

“…After the electron acceptor was replaced by ICBA, the values of V oc increased; for example, to 0.77 V at 500 lux – a lighting level typical of heavily used offices . We attribute the higher value of V oc and larger PCE to the higher energy level of the lowest unoccupied molecular orbital (LUMO) of ICBA (Figure ), thereby minimizing energy loss upon exciton separation at the donor–acceptor interfaces. Therefore, although the photocurrent decreased slightly compared with that of the P3HT:PC 60 BM‐based device, the overall PCE still increased to 13.76%.…”

Toward High‐Performance Polymer Photovoltaic Devices for Low‐Power Indoor Applications

This article describes the performance of organic photovoltaic (OPV) devices, incorporating three different polymer/fullerene derivative blends, under low‐level lighting conditions. The devices exhibit much higher power conversion efficiencies (PCEs) under indoor lighting conditions than they do under sunlight. The best‐performing device is capable of delivering a power output of 22.57 μW cm−2, corresponding to a PCE of 13.76%, under illumination with indoor lighting conditions at 500 lux. Increasing the open‐circuit voltage (Voc) of the OPV devices is the most critical factor for achieving high device performance for low‐power indoor applications. Therefore, the device power output will be maximized if we could obtain a larger energy difference between the highest occupied molecular orbital of the polymer donor and the lowest unoccupied molecular orbital of the electron acceptor, thereby ensuring a high value of Voc.

Metal nanoparticle-decorated graphene oxides are promising materials for use in various optoelectronic applications because of their unique plasmonic properties. In this paper, a simple, environmentally friendly method for the synthesis of gold nanoparticle-decorated graphene oxide that can be used to improve the efficiency of organic photovoltaic devices (OPVs) is reported. Here, the amino acid glycine is employed as an environmentally friendly reducing reagent for the reduction of gold ions in the graphene oxide solutions. Transmission electron microscopy, atomic force microscopy, X-ray photoelectron spectroscopy, UV-Vis spectroscopy, and Raman spectroscopy are used to characterize the material properties of the resulting nanomaterials. Furthermore, these nanocomposites are employed as the anode buffer layer in OPVs to trigger surface plasmonic resonance, which improved the efficiency of the OPVs. The results indicate that such nanomaterials appear to have great potential for application in OPVs.
