Explore perovskite solar cell structures with Indigo® crystal lattice molecular models. Learn bandgap tuning, cation substitution, and optoelectronic design.
Hybrid perovskites such as cesium lead bromide (CsPbBr3) have transformed solar cell and LED research, pushing photovoltaic efficiencies beyond 25% and enabling high-performance photodetectors and displays. The Indigo® perovskite crystal lattice molecular model illustrates the ABX3 lattice, helping students and researchers visualize how cation and anion substitution alters symmetry, stability, and bandgap energy. By manipulating the structure, learners can connect crystal chemistry to optoelectronic properties that underpin solar and light-emitting device performance.
This perovskite optoelectronic teaching tool highlights the direct link between structure and function. Demonstrating bandgap tuning in perovskite lattices with halide substitutions such as CsPbBr3, this crystal model kit, supports advanced lessons in solid-state chemistry and materials science. It is equally valuable in courses on energy materials, nanotechnology, and sustainable device engineering.
Indigo Instruments has held inventory of genuine Cochranes of Oxford (Orbit) parts for 30+ years (See Skeletal (Orbit/Minit)) that are compatible with every molecular model we have sold since day 1. This level of quality may appear expensive but no parts support from other vendors costs even more.

There are no printed instructions for assembling this model. However, these specifications & a close look at the images of the model & unit cell should suffice.
While this kit is best suited to illustrating simple inorganic perovskites such as CsPbBr3, it also provides useful structural context for understanding hybrid perovskites like methylammonium lead iodide (MAPbI?), even if the organic A-site cation cannot be directly represented.
