Improving the optical properties of thin film plasmonic solar cells of InP absorber layer using nanowires

In this paper, a thin-film InP-based solar cell designed and simulated. The proposed InP solar cell has a periodic array of plasmonic back-reflector, which consists of a silver layer and two silver nanowires. The indium tin oxide (ITO) layer also utilized as an anti-reflection coating (ARC) layer on top. The design creates a light-trapping structure by using a plasmonic back-reflector and an an...

Thin-film Silicon Solar Cells

The simplest semiconductor junction that is used in solar cells for separating photogenerated charge carriers is the p-n junction, an interface between the p-type region and ntype region of one semiconductor. Therefore, the basic semiconductor property of a material, the possibility to vary its conductivity by doping, has to be demonstrated first before the material can be considered as a suita...

SnSe2 quantum dot sensitized solar cells prepared employing molecular metal chalcogenide as precursors.

A kind of molecular metal chalcogenide, (N(2)H(4))(3)(N(2)H(5))(4)Sn(2)Se(6) complex, was synthesized in the hydrazine solution and employed as the precursors for SnSe(2) deposition on TiO(2) nanocrystalline porous films. A power conversion efficiency of 0.12% under AM 1.5, 1 sun was obtained for the SnSe(2) sensitized TiO(2) solar cells.

Admittance spectroscopy of thin film solar cells

A short overview on thin film solar cells is given, and the complexity of their electronic structure is illustrated. Several physical mechanisms that give rise to a decay of the capacitance from a low-frequency value CLF to a high-frequency value CHF are discussed. A key of interpreting features in measured admittance spectroscopy (AS) spectra is a careful analysis of CLF and CHF and the temper...
