Effect of trap depth and interfacial energy barrier on charge transport in inverted organic solar cells employing nanostructured ZnO as electron buffer layer
Inverted organic solar cells with device structure ITO/ZnO/poly (3–hexylthiophene) (P3HT):[6,6]–phenyl C61 butyric acid methyl ester (PCBM)/MoO3/Ag were fabricated employing low temperature solution processed ZnO as electron selective layer. Devices with varying film thickness of ZnO interlayer were investigated. The optimum film thickness was determined from photovoltaic parameters obtained from ...

Alternative Energy: Small Molecule Semiconductor Materials to Improve the Luminous Efficiency of OLEDs
Small molecule semiconductor building blocks have special optoelectronic properties that are different from inorganic or polymer semiconductor materials. Compared with inorganic semiconductor materials, there are many types of small-molecule semiconductor materials, and there is a lot of room for the choice of material types. Secondly, molecular synthesis and modification can be used to achieve ...

For cheaper solar photovoltaic systems
It is known for several decades, photovoltaic devices that exploit the sun's energy to convert into electricity used to provide a sustainable alternative - and potentially unlimited - the use of fossil fuels. So why these solar technologies have they not been adopted more widely? Simply “because they are too expensive," said Ji-Seon Kim, professor of Solid Physics at Imperial College of ...

Application of Buffer Layer Materials to Improve the Stability and Photoelectric Conversion Efficiency of OPV Devices
As a new type of green energy technology, organic solar cells (OPVs), the core of which is to use photoelectric conversion organic materials to convert light energy into electrical energy, have the advantages of all-solid-state, low cost, low temperature fabrication and large-area flexible devices. The photocurrent flow of OPV depends not only on photogenerated carriers but also on the interface ...

The future of Solar Power
When you think of renewable energies, what do you think of? Hydro power? Wind energy? In fact, they have proven to be the most popular in recent years. Hydro power in its current form is the cheapest of the renewable energies. Wind power is the fastest growing. However, there is a renewable energy that is far more versatile and has the potential to achieve a higher ROI than the ones mentioned ...

Tungsten trioxide nanostructured electrodes for organic dye sensitised solar cells
Tungsten trioxide (WO 3 ) nanospheres with diameter ranging from 10 nm to 500 nm were synthesised by a facile thermal oxidation process. By resistively heating metallic tungsten in oxygen atmosphere, WO 3 nanoparticles were produced in high yield. Optical, compositional, morphological and structural studies were performed by UV-VIS-NIR spectrophotometry, X-ray photoelectron spectroscopy ...
