Ultra-thin transparent silver films for solar cells

Ultra-thin transparent silver films for solar cells

A new fabrication process for transparent ultra-thin silver films has been developed. The material may help build highly efficient solar cells and light-emitting diodes. However, traditional chemical methods have not been able to produce ultra-thin and pure silver films.

Thin films for more efficient solar cells

Thin films for more efficient solar cells

The efficiency of solar cells can be increased by thin-film contacts. Improving the performance of solar cells requires scrutinizing every aspect of their design. First, this means improving the crystalline quality of the absorbing material to maximize the conversion of photons to negatively charged electrons and positively charged holes. Next, the device's architecture must be optimized to ensure these charge carriers can move efficiently…

Patented nanostructure for solar cells: Rough optics, smooth surface

Patented nanostructure for solar cells: Rough optics, smooth surface

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team has now patented a sophisticated new solution to this problem.

Solar cells need to slim down

Solar cells need to slim down

Thin-film solar cells could be 1/100th the thickness of a piece of paper and flexible enough to festoon surfaces ranging from an aerodynamically sleek car to clothing. To make thin-film solar cells, scientists are moving beyond the "classic" semiconductor compounds, such as gallium arsenide or silicon, and working instead with other light-harvesting compounds that have the potential to be cheaper and easier to mass produce. The compounds could be…
