The main goal of BI-DSC project is to contribute to an enhancement in the performance and reliability of DSCs and solve the critical constrains that prevent their commercialization. Other assumed objective of this project is to make DSCs the most desirable photovoltaic technology for buildings.

In the last decades, solar and photovoltaic (PV) technologies have emerged as a potentially major technology for power generation in the world. So far the PV field has been dominated by silicon devices, even though this technology is still expensive.

Dye-sensitized solar cells (DSC) are an important type of thin-film photovoltaics due to their potential for low-cost fabrication and versatile applications, and because their aesthetic appearance, as semi-transparency and different color possibilities. These advantageous characteristics make DSC the first choice for building integrated photovoltaics. Despite their great potential, DSCs for building applications are still not available at commercial level. However, to bring DSCs to a marketable product several developments are still needed and the present project targets to give relevant answers to three key limitations: encapsulation, glass substrate enhanced electrical conductivity and more efficient and low-cost raw-materials.

BI-DSC proposal envisages the development of DSC modules, containing four individual cells, and their incorporation in a 1 m2 double glass sheet arrangement for BIPV with an energy efficiency of at least 9 % and a lifetime of 20 years. Effective sealing of DSC will be done by laser assisted glass sealing.  Aiming at enhanced efficiency of the final device and decreased total costs of DSCs manufacturing, new materials will be also pursued. The following inner-components were identified as critical: carbon-based counter-electrode; carbon quantum-dots and hierarchically TiO2 photoelectrode.

The project is divided into two research parallel directions: a fundamental research line, contributing to the development of the new generation DSC technology; while a more applied research line targets the development of a DSC functional module that can be used to pave the way for its industrialization.
