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.
Fuel cells have the potential to reduce the nation’s energy use through increased energy conversion efficiency and dependence on imported petroleum by the use of hydrogen from renewable resources.
