Dye sensitized solar cells (DSCs) are one of the most promising cost effective emerging technologies for clean energy generation using solar radiation. Though many of the highest efficiencies have been associated with Ru...
Significant progress in power conversion efficiencies and stabilities of polymer solar cells has been achieved using semiconducting metal oxides as charge extraction interlayers. Both n- and p-type transition metal oxide...
Electrochemical capacitors - also called supercapacitors - represent a relatively new electricity storage system applied for harvesting energy and delivering high power pulses for short periods. The main developed techno...
The Schottky junction, with merits of material universality, low cost and easy fabrication, is an alternative structure for solar cells. Compared to traditional indium-tin-oxide (ITO) based Schottky junction solar cells,...
Carbon nanodots (C-dots) have generated enormous excitement because of their superiority in water solubility, chemical inertness, low toxicity, ease of functionalization and resistance to photobleaching. In this review, ...
Conjugated polymer-based bulk heterojunction (BHJ) solar cells are widely recognized as a promising alternative to their inorganic counterparts for achieving low-cost, roll-to-roll production of large-area flexible light...
Stability of polymer solar cells (PSCs) is critically important for PSCs to be commercialized. The performance deterioration of PSCs arises mainly from macrophase separation of the finely tuned nanoscale morphology of do...
Precious-metal catalysts, predominantly platinum (Pt), have been used to minimize the overpotentials for both the oxidation and reduction of water. This article focuses on the catalytic activity of non-Pt metal nanoparti...
Solar cells involving organic small molecules and polymers have attracted intense attention from chemists, physicists and materials scientists in the past decade. Efforts in materials synthesis and device processing have...
Open-circuit voltage (V-OC) is the maximum voltage a solar cell can provide to an external circuit, which is derived from the splitting of hole and electron quasi-Fermi levels. In crystalline Si solar cells, the effectiv...
Nest-shaped TiO2 (NS-TiO2) structures were fabricated by an electrospinning technique and used as an effective scattering layer on the top of TiO2 nano-particle electrodes in dye sensitized solar cells (DSSCs). The NS-Ti...
We investigate the temperature and power dependence of the emission quantum yield of NaYF4:Er,Yb upconverters. We show that the quantum yields may vary by almost three orders of magnitude. We demonstrate that formation o...
The microstructures and Seebeck coefficients of thermoelectric alloys in the pseudo-ternary PbTe-Ag2Te-Sb2Te3 system were examined using samples that were compositionally graded by unidirectional solidification by the Br...
The role of graft and diblock ionomer architecture on the morphology and properties of ionomer/fluoropolymer blends is examined. The graft copolymer consists of a partially fluorinated backbone of P(VDF-co-CTFE) and part...
In this work, three new quinacridone-based dyes containing a furan moiety (QA1-3) have been synthesized through simple synthetic routes for the application of dye-sensitized solar cells (DSSCs). Their absorption spectra,...
