Among the large family of metallic oxides, there is a considerable group possessing excellent semiconducting properties. What follows, they are promising materials for applications in field optoelectronics and photonics. Thanks to development nanotechnology last few decades, it now possible manufacture great variety different nanostructures. By controlling their size, shape, composition crystallinity, one can influence such properties as band gap, absorption properties, surface volume ratio,...
In the frame of this article different approaches for enhancement UV response silicon photodetectors are being reviewed and analysed. The approach nanoparticles possessing wavelength-shifting properties is specifically explored. A model numerical simulations elaborated basing on initial calculations anticipated responsivity change a detector can be predicted. practical realization proposed concept performed using zinc oxide nanoparticles.
Abstract The paper presents research focused on the efficiency improvement of inorganic flexible thin-film solar cells, using energy converting layers. light capture enhancement was achieved through introduction layers based rare-earth elements, as top coatings amorphous silicon photovoltaic structures. Such luminescent are high-energy photons into low-energy ones, which more efficient in conversion investigated cells. Towards this goal, powders consisting elements were applied active...
The mismatch between solar cell response and spectrum is one of the biggest challenges to achieve high efficiency in photovoltaic cells. There are a few different approaches minimise this concern. One them radiation conversion which may be due three processes, namely up-conversion, down- down-shifting. In paper down-conversion process zinc oxide nanoparticles (ZnO NPs) layers with ZnO NPs polymer (poly (methyl methacrylate)) (PMMA) matrix will analysed. prone act as down-converting or...

The article p resents operation principle, measurement results and perspectives connected with the implementation of textured structure, acting as a selectively transparent layer on top surface flexible, thin-film solar cell optical converter. analyzed structure is designed for application in down-shifting polymer conversion setup, insulation spectrum adjustment.
One of the approaches to augment solar cell efficiency is taking advantage photon converting processes such as up-conversion (UC), down-conversion (DC) and down-shifting (DS). Herein, numerical simulations DS layers based on two different kinds zinc oxide nanoparticles (ZnO NPs) are presented. The models have been elaborated basing measured photoluminescent optical properties these layers.
