High Efficiency Quantum Dot Solar Cells

Scientists Make Significant Progress Toward High Efficiency Quantum Dot Solar Cells

The researchers successfully embedded 20nm-diameter germanium quantum dots (Ge QDs) inside smooth, round shells of silica (silicon dioxide); dispersed the coated quantum dots on a surface with a simple spraying technique; and coated the layer with a film of silicon dioxide using Natcore’s liquid phase deposition (LPD) process.

New Solar Energy Research Laboratory for Lawrence Berkeley National Lab

These will include methods for synthesizing new light absorbing materials, catalysts for fuel generation, separation membranes, and assembly methods to build a complete integrated system. The goal is to develop prototype artificial photosystems capable of robustly producing a fuel from sunlight ten times more efficient than current crops, only using non-arable land.
