Journal ArticleDOI

A low-cost, high-efficiency solar cell based on dye-sensitized colloidal TiO2 films

Brian O'Regan, +2 more
- 24 Oct 1991 - 
TL;DR: In this article, the authors describe a photovoltaic cell, created from low-to medium-purity materials through low-cost processes, which exhibits a commercially realistic energy-conversion efficiency.
Journal ArticleDOI

Sequential deposition as a route to high-performance perovskite-sensitized solar cells

Julian Burschka, +7 more
- 18 Jul 2013 - 
TL;DR: A sequential deposition method for the formation of the perovskite pigment within the porous metal oxide film that greatly increases the reproducibility of their performance and allows the fabrication of solid-state mesoscopic solar cells with unprecedented power conversion efficiencies and high stability.
Journal Article

Photoelectrochemical cells : Materials for clean energy

Michael Grätzel
- 01 Jan 2001 - 
TL;DR: In this paper, the authors look into the historical background, and present status and development prospects for photoelectrochemical cells, based on nanocrystalline materials and conducting polymer films.
Journal ArticleDOI

Lead Iodide Perovskite Sensitized All-Solid-State Submicron Thin Film Mesoscopic Solar Cell with Efficiency Exceeding 9%

Hui-Seon Kim, +11 more
- 21 Aug 2012 - 
TL;DR: The use of a solid hole conductor dramatically improved the device stability compared to (CH3NH3)PbI3 -sensitized liquid junction cells.
Journal ArticleDOI

Long-Range Balanced Electron- and Hole-Transport Lengths in Organic-Inorganic CH3NH3PbI3

Guichuan Xing, +8 more
- 18 Oct 2013 - 
TL;DR: Two studies show, using a variety of time-resolved absorption and emission spectroscopic techniques, that perovskite materials manifest relatively long diffusion paths for charge carriers energized by light absorption, highlighting effective carrier diffusion as a fruitful parameter for further optimization.
