This paper presents the application of nanoparticles in photovoltaic (PV) cells. The nanoparticles used in this work were dispersed in the active layer of the cell. This modification raised power conversion efficiency and open circuit voltage of PV cells. Organic single layered PV device has been developed using ITO/PEDOT:PSS (poly(3,4-ethylene dioxythiophene)-poly-(styrene sulphonate)/active layer with nano-sized particles/Al architecture. Streszczenie. W artykule przedstawione zostały organiczne ogniwa fotowoltaiczne z dodatkiem nanocząstek. Zastosowane nanocząstki zostały wprowadzone do całej objętości warstwy aktywnej ogniwa, dzięki czemu zaobserwowano wzrost wydajności konwersji mocy oraz napięcia obwodu otwartego ogniwa. Struktura ogniwa była wykonana w sposób warstwowy ITO/PEDOT:PSS/warstwa aktywna z nanocząstkami/Al.

Single layer systems with PV activity based on semiconducting polymers are easy to built using deposition techniques such as spin coating or vacuum evaporating. In comparison with inorganic PV devices the contemporary organic ones have an advantage of the lower weight, flexible shape, versatile technological process and the low cost in large-scale industrial [...]

Azaheterocyclic materials for organic photovoltaic cells


  Recently we can observe growing interest in organic photovoltaic cells. Nowadays, when the development of renewable sources of energy is necessary, photovoltaic energy becomes an opportunity to reduce consumption of fossil fuels. Organic photovoltaic cells are easy built by deposition techniques like spin coating, moreover PV devices have lower weight, flexible shape and low production cost in comparison with inorganic equivalents [1]. These features have fuelled the interest of both science and industry. The conversion of solar light into electric power requires the generation of both negative and positive charges. The operation of a photovoltaic cell can be generally divided into three basic steps: light absorption, charge separation and charge collection of the appropriate carriers to anode and metallic cathode.When photons are absorbed, only small part of incident light is absorbed because of size of ba[...]
