Effects of Sensitization with Natural Pigments on the Performance of Dye-sensitized Solar Cell (DSSC)

Three natural pigments including wild iris, black pomegranate bark and black grapes were used as sensitizer in dye sensitized solar cells (DSSCs) based on TiO2 nanoparticles. The results showed that the DSSC made of black pomegranate bark was more efficient than the other cells due to its strong bonding with TiO2 nanoparticles. Longer electron lifetime, lower electron recombination, and lower...

Recycling of CIGS solar cell waste materials

The increased interest in solar power over the last few decades has led to a constant development of existing and new types of solar cells. One type of solar cell that is making advances on the global market is copper indium gallium diselenide (CIGS) thin film solar cells. The advantage of thin film solar cells is that they require less semiconductor material than conventional silicon solar cel...

Improving the performance of cadmium telluride solar cell (CdTe) with different buffer layers

In this paper, the performance of the buffer layer of Cadmium Telluride (CdTe) thin film solar cell was optimized using SCAPS software. At first, five different buffer layers including CdS, In2S3, ZnO, ZnSe and ZnS with variable thicknesses from 10 to 100 nm have been replaced in the structure of the solar cell and it has been observed. As the thickness of the buffer layer is increased, the eff...

Reporting solar cell efficiencies in Solar Energy Materials and Solar Cells

In order to improve the accuracy, validity, reliability and reproducibility of reported power conversion efficiencies for solar cells, the journal, Solar Energy Materials and Solar Cells (SOLMAT), wishes to define how power conversion efficiencies should be reported. This expands upon what is specified in our Guide for Authors. This editorial also serves as a guide on how efficiency data should...
