Ion-Coordinating Sensitizer in Solid-State Hybrid Solar Cells

Ion-coordinating sensitizer in solid-state hybrid solar cells.

The solid state dye sensitized solar cell is one of the most promising organic based device concepts which demonstrates solar power conversion efficiencies in excess of 4%. The basic strategy of this hybrid system is that light is absorbed in a dye to form an excited electronic state, termed an exciton. Electron transfer takes place from the excited dye molecule to an inorganic semiconductor, w...

All-solid-state hybrid solar cells based on a new organometal halide perovskite sensitizer and one-dimensional TiO2 nanowire arrays.

A novel organometal halide perovskite (CH3NH3PbI2Br) is synthesized and used as a visible light absorber to sensitize one-dimensional (1D) TiO2 nanowire arrays (NWAs) for all-solid-state hybrid solar cells. It achieved a power conversion efficiency (PCE) of 4.87% and an open circuit voltage (Voc) of 0.82 V, both higher than those of its analogue CH3NH3PbI3.

Emerging Solar Cell Technology: Advances in Solid-state Polymer Hybrid Dye-sensitized Solar Cells

and Abstract My project this summer took place in the lab of Dr. in the Oxford Physics Department. I worked for ten weeks on solid-state dye-sensitized solar cells that incorporated the polymer hole-transporter poly(3-hexylthiopene) (P3HT) and a number of different dyes. The larger goal of the project is to extend solid-state solar cells' photoresponse by taking advantage of a favorable energy-...

Application of hybrid blocking layers in solid-state dye-sensitized solar cells

A hybrid blocking layer consisting of a conducting TiO2 network embedded in a ceramic matrix is implemented in a solid-state dye-sensitized solar cell. This novel type of blocking layer is thinner than the classical blocking layer films as shown with SEM and XRR measurements, and thereby the conductivity of the hybrid film is increased by 110%. A percolating TiO2 network, proven by TEM/ESI and ...
