Recovery of Valuable Materials from End-of-Life Photovoltaic Solar Panels.

The disposal of end-of-life (EOL) photovoltaic solar panels has become a relevant environmental issue as they are considered to be a hazardous electronic waste. On the other hand, enormous benefits are achieved from recovering valuable metals and materials from such waste. Eventually, physical and chemical processing will become the most important stages during the recycling process.

Semiconductors as Effective Electrodes for Dye Sensitized Solar Cell Applications.

As proficient photovoltaic devices, dye-sensitized solar cells (DSSCs) have received considerable consideration in recent years. In order to accomplish advanced solar-to-electricity efficiency and increase long-term functioning stability, improvements in the configuration structure of DSSCs are essential, as is an understanding of their elementary principles. This work discusses the application of different semiconductor constituents designed for effective DSSCs.

Solid-state dye-sensitized solar cells based on Zn Sn O nanocomposite photoanodes.

Solid-state dye-sensitized solar cells (ss-DSSCs) comprising Sn-substituted ZnO nanopowder were purposefully tailored a co-precipitation method. The solar cells assembled in this work were sensitized with N719 ruthenium dye and insinuated with spiro-OMeTAD as a solid hole transport layer (HTL). Evidently, significant enhancement in cell efficiency was accomplished with Sn ions-substituted ZnO photoelectrodes by maintaining the weight ratio of SnO at 5%.
