The science is correct. I'm not aware of much application of it commercially as of yet, up until relatively recently the higher efficiency of the silicon PN junction process has made better use of the surface area. However, a major area of advancement on the horizon is multi-junction panels. These stack different semiconductors which each harness different wavelengths of light to harness more of the sun's relatively wide band of light. I'm not sure exactly what junction chemistries we'll see in these going forward, but I'm sure the industry will be trying out just about every configuration we can manufacture.
