Light intensity, temperature, and thickness dependence of the open-circuit voltage in solid-state dye-sensitized solar cells
We present an analytical and experimental investigation into the origin of the open-circuit voltage in the solid-state dye-sensitized solar cell. Through Kelvin probe microscopy, we demonstrate that a macroscopically uniform electric field exists throughout the nanocomposite between the electrodes. Considering a balance between drift and diffusion currents, and between charge generation and rec...
متن کاملDevice modeling of dye-sensitized solar cells.
We review the concepts and methods of modeling of the dye-sensitized solar cell, starting from fundamental electron transfer theory, and using phenomenological transport-conservation equations. The models revised here are aimed at describing the components of the current-voltage curve of the solar cell, based on small perturbation experimental methods, and to such an end, a range of phenomena o...
متن کاملInfluence of TiO2 layer thickness as photoanode in Dye Sensitized Solar Cells
Dye-sensitized solar cells (DSSCs) are categorized as some of inexpensive thin-film solar cells. The basis and foundation of these cells is a semiconductor that consists of an electrolyte and a light-sensitive anode. Titanium dioxide (TiO2) is a semiconductor that plays the role of anode and is the main constituent of these cells. In this paper, we have addressed the functionality and performan...
متن کاملContribution from a hole-conducting dye to the photocurrent in solid-state dye-sensitized solar cells.
The hole transporting medium in solid-state dye-sensitized solar cells can be utilized to harvest sunlight. Herein we demonstrate that a triphenylamine-based dye, used as hole-transporting medium, contributes to the photocurrent in a squaraine-sensitized solid-state dye-sensitized solar cell. Steady-state photoluminescence measurements have been used to distinguish between electron transfer and...
