Dye-sensitized solar cells directly convert sunlight to electricity
Over the last decade, dye-sensitized solar cells (DSSCs) have attracted much attention because these unconventional solar cells exhibit high performance and have the potential for low-cost production.
One of the more traditional photovoltaic devices, single crystalline silicon solar cells were invented more than 50 years ago, currently make up 94% of the market. Single crystalline silicon solar cells operate on the principle of p-n junctions formed by joining p-type and n-type semiconductors.
Titanium dioxide (TiO2) is an important n-type semiconducting material that shows interesting characteristics such as photoswitchable surface wettability, high photocatalytic activity, bistable electrical resistance states and high electron drift mobility.
