Temperature dependent current–voltage and photovoltaic properties of chemically prepared (p)Si/(n)Bi2S3 heterojunction

Improved Photovoltaic Properties of Heterojunction Carbon Based Solar Cell

Amorphous carbon (a-C) thin films have been synthesized by microwave (MW) surface wave plasma (SWP) chemical vapor deposition (CVD) on n-type silicon and quartz substrates, aiming at the application of the films for photovoltaic solar cells. Argon, acetylene and trimethylboron were used as a carrier, source and dopant gases. Analytical methods such as X-ray photoelectron spectroscopy (XPS), Hal...

Photovoltaic properties of ZnO nanorods/p-type Si heterojunction structures

Selected properties of photovoltaic (PV) structures based on n-type zinc oxide nanorods grown by a low temperature hydrothermal method on p-type silicon substrates (100) are investigated. PV structures were covered with thin films of Al doped ZnO grown by atomic layer deposition acting as transparent electrodes. The investigated PV structures differ in terms of the shapes and densities of their...

Enhanced photovoltaic properties in graphene/polycrystalline BiFeO3/Pt heterojunction structure

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

Investigation of Temperature-Dependent Electrical Properties of Tc-CuPc: PCBM Bulk Heterojunction (BHJ) under Dark Conditions

An organic bulk heterojunction (BHJ) was fabricated using a blended film containing Copper (II) tetrakis(4cumylphenoxy)phthalocyanine (Tc-CuPc) along with [6,6]-Phenyl C61 butyric acid methyl ester (PCBM). Weight ratio between TcCuPc and PCBM was 1:1. The electrical properties of TcCuPc:PCBM BHJ were examined. Rectifying nature of the BHJ was displayed by current-voltage (I-V) curves, recorded ...
