Light trapping is a promising approach, e.g., by scattering the incident light to oblique angle to increase the dwell time of the light inside the devices, to improve light absorption in the active layer in organic solar cells (OSCs). In this work, the absorption enhancement in OSCs is realized using a poly(methyl methacrylate) (PMMA)/indium-tin-oxide (ITO) grating electrode. Photovoltaic properties such as external quantum efficiency and power conversion efficiency of a set of structural identical OSCs made with a planar ITO anode (control device) and a PMMA/ITO grating electrode were analyzed. The grating incorporated OSCs resulted in a ~10% increase in …

Compared to current silicon-based solar cells that are rigid, organic-based solar cells that use solution-based processing or low-cost non-vacuum deposition techniques are simpler and less expensive to manufacture. Organic photovoltaic cells can be made flexible, semitransparent and are light weight, offer more opportunities for application in new markets such as mobile electronics, disposable electronics, smart cards, digital applications, power generating windows, smart sensors, automotive, home appliances and outdoor lifestyle etc. Its unique flexibility and semi-transparency feature also adds a decorative and aesthetic dimension to the solar cells so that it can be used on curved and irregular surfaces – something …

The significant enhancement in power efficiency of tandem organic light-emitting diodes (OLEDs) was achieved using bulk heterojunction organic bipolar charge generation layer (CGL), consisted of zinc phthalocyanine (ZcPc): fullerene (C60) blend. In addition to a significant enhancement in luminance and current efficiency this work yielded a maximum power efficiency of 21 lm/W measured for a tandem OLED, which is notably almost two times higher than that of a single-unit device, with a maximum power efficiency of 10.1 lm/W. The enhancement in power efficiency at higher luminance is also over 90%. The remarkable enhancement in power efficiency has been attributed to …

In this work, Ag nanoparticles were modified by an ultra-thin plasma-polymerized fluorocarbon film (CFX) to form a composite CFX -modified Ag nanoparticles/indium tin oxide (ITO) anode for application in organic photovoltaic (OPV) devices. A CFX-modified Ag nanoparticles/ITO anode exhibited a superior surface work function of 5.4 eV suited for application in OPV devices. The device performance of zinc phthalocyanine:fullerene-based OPV devices showed a significant improvement when the structural identical cells are made with the CFX-modified Ag nanoparticles/ITO. This work yielded a promising power conversion efficiency of 3.50.1%, notably higher than that with a bare ITO anode (2.70.1%).
