This special issue aims to be a worthy prosecution of the TFPV series, published in the years 2010, 2012, and 2013. Following the structure of the previous special issues, TFPV 2014 is seeking contributions from scientists and specialists in photovoltaics (PV) involved in the development of both scientific and technological features in the field.

The purpose of TFPV 2014 will be bringing additional knowledge and update, addressing the immense challenges remaining in understanding, and overcoming the key scientific issues in the conversion of solar energy into electricity, a fundamental step to fulfill the potential for applications. Technological aspects in the development of large area devices, urgently needed in response to the economic crisis of recent years, will also be covered in the special issue.

Potential topics include, but are not limited to:

• Dye sensitized solar cells (DSSCs)
• Hybrid solid-state solar cells (perovskites, quantum dots, metal chalcogenides, etc.)
• Organic solar cells
• Inorganic solar cells (CIS, CIGS, amorphous silicon, etc.)
• Technologies for photovoltaic applications

Manuscripts regarding scientific breakthrough, technical matters, and industrialization are well accepted. This special issue, particularly, will welcome all those contributions related to new frontiers achieved by the DSSC’s in terms of basic research and technological applications.
