A green, efficient and stable solar cell based only on water and safe and cheap elements of the periodic table is proposed in this work, finally consolidating (also from a sustainability viewpoint) the concept of "artificial photosynthesis" studied for dec ...
Solar energy is the most abundant energy source, harnessing solar energy holds the solution to the challenge of increasing global energy demand and reducing our dependence on fossil fuels. Photovoltaics which directly convert solar energy into electricity ...
Renewable energy deployment and implementation of a circular economy will play a crucial role in decreasing CO2 emissions to meet the target from the Paris agreement.
Dye-sensitized solar cells (DSSCs) can be designed in various colors and transparency for ...

Two types of nanosized niobium oxides and their composites, pseudohexagonal Nb2O5 (TT-Nb2O5), monoclinic NbO2 (M-NbO2), and the coexistence of TT-Nb2O5 and M-NbO2 (TT-Nb2O5/M-NbO2), are successfully synthesized through the urea-metal chloride route, and th ...
Auxiliary donors are common design motifs for phenothiazine sensitizers for dye-sensitized solar cells. Despite this, there are only a few reports on their overall contribution to the photon-to-electron conversion efficiency. Twelve sensitizers have been p ...
O'Regan and Gratzel conceived a dye-sensitized solar cell (DSSC), which operates as an artificial photosynthetic system converting solar light into electricity. Nevertheless, it is only recently that the scientific community is focusing on truly aqueous DS ...
Developing high-performance, low-cost electrocatalysts for the reduction reaction at the cathode of dye-sensitized solar cells (DSCs) is important for their commercialization. Here, we introduce the concept of redox catalysis for improving counter-electrod ...
The present invention relates to a method for producing a solid state solar cell, comprising the steps of providing a conductive support layer or current collector, applying a metal oxide layer on the conducting support layer, applying at least one sensiti ...
