Exploring the potential of semiconducting BaSi2for thin-film solar cell applications

Pentacene-carbon nanotubes: Semiconducting assemblies for thin-film transistor applications

We demonstrate an alternative path for achieving high-transconductance organic transistors by assembling bilayers of pentacene onto random arrays of single-walled carbon nanotubes. We show here that, by varying the connectivity of the underlying nanotube network, the channel length of a thin-film transistor can be reduced by nearly two orders of magnitude—thus, enabling the increase of the devi...

Effect of Annealing on Physical Properties of Cu2ZnSnS4 (CZTS) Thin Films for Solar Cell Applications

Cu2ZnSnS4 (CZTS) thin films were prepared by directly sputteringCu (In,Ga)Se2 quaternary target consisting of (Cu: 25%, Zn: 12.5%, Sn; 12.5%and S: 50%). The composition and structure of CZTS layers have beeninvestigated after annealing at 200 0C, 350 0C and 500 0C under vacuum. Theresults show that recrystallization of the CZTS thin film occurs and increasingthe grain size with a preferred orie...

POLYCRYSTALLINE THIN FILM SOLAR CELLS: Present Status and Future Potential

Polycrystalline thin film solar cells based on copper indium diselenide (CuInSe2) and its alloys and cadmium telluride (CdTe) appear to be the most promising candidates for largescale application of photovoltaic energy conversion because they have shown laboratoryefficiencies in excess of 15%. Heterejunction devices with n-type cadmium sulfide (CdS) films show very low minority carrier recombin...

Thin-film Silicon Solar Cells for Space Applications: Radiation Hardness and Applications for an Integrated Solant (solar Cell - Antenna) Module

A new device called “Solant” (for SOLar cell – ANTenna) is presented in this paper. It is a combination of thin-film amorphous silicon solar cells and flat printed antennas. A proton irradiation campaign has also been carried out on a series of n-i-p amorphous and p-i-n micromorph [microcrystalline (μc-Si:H) and amorphous (a-Si:H)] silicon tandem solar cells. The effect of thermal annealing on ...
