Energy consumption is increasing yearly all over the world due to increase in population and demand of energy. The largely depends on a hydroelectric energy supply, thermal electric supply which non-renewable resources. Nevertheless, resources are rapidly decreasing per year rate consumption. quest for discovery another abundant resource has attracted many scientists into development renewable ...
Background Grätzel solar cell, also known as dye-sensitized solar cell (DSSC), is a dye-sensitized nanocrystalline photovoltaic cell of TiO2 (titanium dioxide). It has a surface of nanoporous TiO2, a semiconductor of a wide bandgap. The basic principle is to transform light energy into electrical energy. When a dye molecule absorbs light, an electron is replaced by an excited state, and this dy...
The past few years have been great for semiconductor quantum dot-sensitized solar cells (QDSSCs). For the first time, efficiency exceeding 15% has reported. This narrowed gap with other emerging cell technologies such as dye-sensitized and thin film cells. In this miniperspective, reason improvement is briefly reviewed. Few advancements identified that are responsible performance breakthrough i...
Dye sensitized solar cell was assembled using TiO2 nanoparticle with argon-nitrogen plasma treatment and CuBi2O4 sputtering electrode prepared by plasma irradiation. The electric property of the solar cell fabricated by plasma treated TiO2 nanoparticle was improved because the physical and chemical property of TiO2 particles affected from the nitrogen plasma treatment
Novel highly asymmetric zinc tetraazaporphyrin (TAP) derivatives (Zn-tri-TAPNc and Zn-tri-PcNc) with one carboxyl and three tert-butyl peripheral substituent groups were synthesized. A highly asymmetric zinc phthalocyanine (ZnPc) derivative (Zn-tri-PcNc) has a benzo-annelated ring which contains tribenzonaphtho-condensed tetraazaporphyrin with the same peripheral substituents as Zn-tri-TAPNc. A...
In the present study, protoporphyrin IX (PPIX) and squarine (SQ2) have been used in a co-sensitized dye-sensitized solar cell (DSSC) to apply their high absorption coefficients in the visible and NIR region of the solar spectrum and to probe the possibility of Förster resonance energy transfer (FRET) between the two dyes. FRET from the donor PPIX to acceptor SQ2 was observed from detailed inves...
The efficiency of solar cells depends on absorption intensity of the photon collectors. Herein, mobile quantum dots (QDs) functionalized with thiol ligands in electrolyte are utilized into dye-sensitized solar cells. The QDs serve as mediators to receive and re-transmit energy to sensitized dyes, thus amplifying photon collection of sensitizing dyes in the visible range and enabling up-conversi...
