Here we present an ultraviolet responsive inorganic-organic hybrid solar cell based on titania/poly(3-hexylthiophene) (TiO(2)/P3HT) heterojuction. In this solar cell, TiO(2) is an ultraviolet light absorber and electronic conductor, P3HT is a hole conductor, the light-to-electrical conversion is realized by the cooperation for these two components. Doping ionic salt in P3HT polymer can improve ...

Progress in use of carbon materials, particularly those prepared from bio-sourced precursors, as electrodes for energy conversion & storage, separately, and combining supercapacitors solar cells one single system.

To address the problems of climate change and energy security, Chinese government strived to develop renewable power as an important alternative of conventional electricity. In this paper, the learning curve model is employed to describe the decreasing unit investment cost due to accumulated installed capacity; the technology diffusion model is used to analyze the potential of renewable power. ...

Appropriate technology for the conversion of solar radiation to thermal energy is vital for food dehydration. Commercial producers of dried foods need reliable drying technologies for continuity technologies for continuity of production. However, solar radiation is not available whenever it is needed to drying. This limitation discourages many of these producers from investing in solar technolo...

In this work, the operation mechanism of hybrid solar cells is studied explicitly. The excitation, diffusion and dissociation of singlet and triplet excitons and charge transport of free charge carriers are studied and their corresponding rates are calculated for a flexible P3HT:SiNW hybrid solar cell. The rates are found to be faster for singlet than triplet excitons. Possible loss mechanisms ...

Performance of a tractor mounted solar-biomass hybrid dryer which utilise combined energy solar and biomass was investigated. Drying behaviour maize grains in the also investigated using 10 thin-layer mathematical models. The models were compared based on coefficient determination (R2) root mean square error (RMSE) values between experimental predicted moisture ratios. Moisture content (MC) red...

In this paper, we have continued doing a research project which had done previously. Three types of power plants include an Organic Rankine Cycle (ORC), a Dual-Fluid-Hybrid (DFH) and a single-fluid hybrid-fueled (HYB); were re-modeled. After model validation, thermodynamic studies and exergy analysis were extended for the defined cases using the first and second laws of thermodynamics. Then the...
