DOI: Concepcion and Jared H. Delcamp and Elizabeth A. Gibson and Gerald J. Freitag Published 30 September Medicine Chemical Society Reviews Dye-sensitized solar cells DSCs are celebrating their 30th birthday and they are attracting a wealth of research efforts aimed at unleashing their full potential.

In recent years, DSCs and dye-sensitized photoelectrochemical cells DSPECs have experienced a renaissance as the best technology for several niche applications that take advantage of DSCs' unique combination of properties: at low cost, they are composed of non-toxic materials, are colorful, transparent, and very efficient in low… Expand.

A platinum electrolyte was added to the cell prior to the collection of current density and voltage data.

The research was conducted as part of the Drexel Smart House, which is a student run organization in Drexel University aimed at sustainable and innovative inventions for potential use at Smart House. Two kinds of TiO2 were used, handmade and magnetic stirred while two spreading techniques were incorporated, namely, Doctor Blading and Spin Coating. The best efficiency found in this study was 0. The other efficiency increasing techniques employed were the use of multiple layers of substrate.

Double layered TiO2 cells were produced, the highest efficiency amongst which was 0. These offer the prospective of very low cost fabrication and present attractive features that facilitate market entry. The gap between particles is smaller, so that the dye amount absorbed is limited. The small surface area of the nanowires limited the efficiencies of these cells.

Major constituents like TiO2 nanoparticles and simple process stages such as sintering make DSSC a cheap and less labor intensive alternative to capturing solar energy. Figure 1: NREL Best Research-Cell Efficiencies [5] The Drexel Smart House The Drexel Smart House DSH is a student organization which has established itself as a launch pad for research and technology at Drexel University, focusing on the renovation of a 19th century urban home into an environmentally conscious, high performance, energy efficient building to serve as a platform for innovation, model for the community, classroom and residence.

Figure 2 shows the envisioned design of the house. With immense support from Dr. Kenneth Lau and his PhD. In the duration of about three months, the conventional procedure of making a DSSC has been practiced and other unconventional methods have also been undertaken.

DSSCs have a very special property of functioning in the presence of artificial light. Ergo, the long term goal of the DSH is to exploit that property and incorporate DSSCs into indoor objects such as lampshades and window blinds. Figure 2: DSH envisioned design [6]. The anode is composed of a transparent mesoporous metal-oxide in this case a layer of nanocrystalline Titanium Dioxide, TiO2 matrix, sensitized with a molecular dye Rhuthenium N When light enters the system the excited dye-sensitizer injects an electron into the TiO2.

The electron is then conducted to a transparent electrically conductive substrate Fluorine Doped Tin Oxide, FTO and flows out of the device. The oxidized dye molecule is reduced to its ground state by a redox-couple present in a surrounding electrolyte Pt. Re-entering the system at the cathode, the electron flows through a FTO substrate and rejoins with the electrolyte.
