Organic Electronic Devices Based on Polymeric Material and Tunable Photonic Crystal

Abstract

The historical background and recent progress in the development of organic electronics and photonic crystals, particularly tunable photonic crystals realized by combining photonic crystal structure with functional organic molecules, are discussed. The novel characteristics of organic electronic devices with mainly conducting polymers, which are related to the optical effects, and the tunable photonic crystals composed of periodic structures of optical wavelength order combined with functional organic materials are demonstrated.

A Review of Organic Photovoltaic Energy Source and Its Technological Designs

“…As shown in Figure 2, literature [23][24][25] has continually shown increases in organic PV solar cell PCEs, with laboratory solar cell efficiency reaching 10% in 2012 [10] and recently increased to~11.2% [26] in OSCs with inverted device structures [27] and~12% in well-optimized OPV systems with nonfullerene acceptor materials [14,28], while more efforts are being explored to improve semiconducting polymeric materials [29][30][31][32][33][34], OPV devices [35], and inorganic-organic hybrid structures [36]. This has led to OSCs and other organic device systems that are integrated with portable devices already being tested [37,38]. The commonly investigated types of OSC structures include those based on the following:…”

Tunable photonic crystals based on MnFe2O4 magnetic fluids by magnetic fields

“…The other is to fabricate the PCs with external-field-sensitive materials so that the refractive index contrast and/or the structures of the PCs can be changed by the external field. Depending on the types of the tunable PCs, different fields, such as magnetic, electric, thermal, and optical fields, can be utilized to tune their forbidden bands [7][8][9][10][11][12][13]. Apparently, the latter fashion of tunability excels the former one because the latter tunability can be realized in real-time mode.…”
