Review on Dye-sensitized Solar Cells Performance Contain Transparent Polymers

Polymeric photovoltaic devices are considered as a green source for energy production because of their low weight, environmental friendly and ease of process. Particularly, transparent polymer photovoltaic devices have attracted more attention because of their unique potential for increasing sunlight absorption. P-type copolymers with D-A structure have been developed as new light-sensitive materials to successfully transmit the absorption spectrum to the IR region, thereby creating transparency. Much of the research focus in transparent organic photovoltaics (TOPV) is on the electrode. PEDOT:PSS copolymer, thin silver, 1D photonic crystal, and other carbon-based transporting layers have proved to be good candidates for transparent electrodes. Among these materials, the composite mirror layers, such as photonic crystal structures, are more favorable in transparent organic photovoltaics because of their tunable reflection spectra that can control both the transmittance and color rendering. The purpose of this paper is to introduce and illustrate transparent photovoltaic polymer devices and the factors affecting their performance. Finally, some brief performance and outlook of the transparent organic photovoltaics are presented.
