We report for the first time the use of a perovskite (CH3NH3PbI3) absorber in combination with ZnO nanorod arrays (NRAs) for solar cell applications. The perovskite material has a higher absorption coefficient than molecular dye sensitizers, gives better solar cell stability, and is therefore more suited as a sensitizer for ZnO NRAs. A solar cell efficiency of 5.0% was achieved under 1000 W m(-...

A new strategy for enhancing the efficiency of TiO2 dye-sensitized solar cells (DSSCs) by doping foreign ion into TiO2 lattice via sol-gel process is reported. DSSCs are based on a semiconductor (i.e., TiO2), formed between a photo-sensitized anode and an electrolyte. In order to reach high conversion efficiency, it is important to increase the electron injection and optical absorption. One pro...

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
