Single-Crystal CdTe Homojunction Structures for Solar Cell …
Amorphous CdS/single-crystal CdTe solar cells were also produced.6 Nevertheless, solar cell performance was still limited by the high density of dislocations and non-optimized junctions. In this work, to fabricate homojunction CdTe cells, we have grown both n-type and p-type CdTe films on GaAs single-crystal substrates by use of different ...

Designing Large-Area Single-Crystal Perovskite Solar Cells
Organic–inorganic halide single-crystal perovskite solar cells (PSCs) are promising for higher efficiency and better stability, but their development lags far behind that of their polycrystalline counterparts. In particular, the low efficiency (<5%) of large-area devices makes the development of an alternative perovskite photovoltaic technology …

OverviewProduction methodsApplicationsIn researchSee alsoFurther reading
In materials science, a single crystal (or single-crystal solid or monocrystalline solid) is a material in which the crystal lattice of the entire sample is continuous and unbroken to the edges of the sample, with no grain boundaries. The absence of the defects associated with grain boundaries can give monocrystals unique properties, particularly mechanical, optical and electrical, which can als…
