Optical description of solid-state dye-sensitized solar cells. I. Measurement of layer optical properties

Michael Graetzel, Henry Snaith

The efficiency of a photovoltaic device is limited by the portion of solar energy that can be captured. We discuss how to measure the optical properties of the various layers in solid-state dye-sensitized solar cells (SDSC). We use spectroscopic ellipsomet ...

Optical description of solid-state dye-sensitized solar cells. II. Device optical modeling with implications for improving efficiency

Michael Graetzel, Henry Snaith

We use the optical transfer-matrix method to quantify the spatial distribution of light in solid-state dye-sensitized solar cells (DSCs), employing material optical properties measured experimentally in the accompanying article (Part I) as input into the o ...

Charge Generation and Photovoltaic Operation of Solid-State Dye-Sensitized Solar Cells Incorporating a High Extinction Coefficient Indolene-Based Sensitizer

Michael Graetzel, Henry Snaith

An investigation of the function of an indolene-based organic dye, termed D149, incorporated in to solid-state dye-sensitized solar cells using 2,2',7,7'- tetrakis(N,N-di-p-methoxypheny-amine)-9,9' - spirobifluorene (spiro-OMeTAD) as the hole transport mat ...

Charge collection and pore filling in solid-state dye-sensitized solar cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Robin Humphry-Baker, Peter Chen, Henry Snaith, Ilkay Cesar

The solar to electrical power conversion efficiency for dye-sensitized solar cells (DSCs) incorporating a solid-state organic hole-transporter can be over 5%. However, this is for devices significantly thinner than the optical depth of the active composite ...

The function of a TiO2 compact layer in dye-sensitized solar cells incorporating "Planar" organic dyes

Michael Graetzel, Henry Snaith, Udo Bach

We present a device based study into the operation of liquid electrolyte dye-sensitized solar cells (DSSC's) using organic dyes. We find that, for these systems, it is entirely necessary to employ a compact TiO2 layer between the transparent fluorine doped ...
