All-inorganic spin-cast nanoparticle solar cells with nonselective electrodes

Spin-cast all-inorganic nanoparticle solutions have been used to make a CdTe/CdSe solar cell with an efficiency of up to 2.6% using air stable electrodes and without an additional alumina layer. The type of junction as well as the nonselective nature of the electrodes of these devices are explored.
