Charge density dependent mobility of organic hole-transporters and mesoporous TiO鈧 determined by transient mobility spectroscopy: implications to dye-sensitized and organic solar cells.

Adv Mater 25:23 (2013) 3227-3233

Authors:

Tomas Leijtens, Jongchul Lim, Jo毛l Teuscher, Taiho Park, Henry J Snaith

Abstract:

Transient mobility spectroscopy (TMS) is presented as a new tool to probe the charge carrier mobility of commonly employed organic and inorganic semiconductors over the relevant range of charge densities. The charge density dependence of the mobility of semiconductors used in hybrid and organic photovoltaics gives new insights into charge transport phenomena in solid state dye sensitized solar cells.

Low-temperature processed meso-superstructured to thin-film perovskite solar cells

Energy and Environmental Science 6:6 (2013) 1739-1743

Authors:

JM Ball, MM Lee, A Hey, HJ Snaith

Abstract:

We have reduced the processing temperature of the bulk absorber layer in CH3NH3PbI3-xClx perovskite solar cells from 500 to <150 掳C and achieved power conversion efficiencies up to 12.3%. Remarkably, we find that devices with planar thin-film architecture, where the ambipolar perovskite transports both holes and electrons, convert the absorbed photons into collected charge with close to 100% efficiency. 漏 2013 The Royal Society of Chemistry.
