Calculated optical absorption of different perovskite phases

We present calculations of the optical properties of a set of around 80 oxides, oxynitrides, and organometal halide cubic and layered perovskites (Ruddlesden-Popper and Dion-Jacobson phases) with a bandgap in the visible part of the solar spectrum. The cal ...

Bistriphenylamine-based organic sensitizers with high molar extinction coefficients for dye-sensitized solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Filippo de Angelis, Hoi Nok Tsao

A series of novel bistriphenylamine-based organic sensitizers (coded as RC-dyes) with high molar extinction coefficients (>5.0 x 10(4) M-1 cm(-1)) have been synthesized for dye-sensitized solar cells (DSSCs). By changing the length of the pi-conjugation br ...

Phenoxazine Dyes for Dye-Sensitized Solar Cells and Relationship Between Molecular Structure and Electron Lifetime

Xiaoqing Jiang, Ulf Anders Hagfeldt

Metal-free org. dyes with a core phenoxazine chromophore have been synthesized and tested as sensitizers in dye-sensitized solar cells. Overall conversion efficiencies of 6.03-7.40% were reached under std. AM 1.5 G illumination at a light intensity of 100 ...

High Molar Extinction Coefficient Organic Sensitizers for Efficient Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Jun Ho Yum, Ines Raabe, Francesca Teocoli

We have designed and synthesized highly efficient organic sensitizers with a planar thienothiophene-vinylene-thienothiophene linker. Under standard global AM 1.5 solar conditions, the JK-113-sensitized cell gave a short circuit photocurrent density (J(sc)) ...
