Not true and Patently false at this juncture.

The theoretical maximum for single-junction, direct bandgap PV, as determined by the Shockley-Queisser limit, is about 33 percent. For indirect bandgap materials such as silicon, this theoretical maximum is 29 percent, according to Frank Averdung, Oxford PV’s CEO.

In addition, Jošt and colleagues have developed a sophisticated numerical model for complex 3D features and their interaction with light. This enabled the team to calculate how different device designs with textures at various interfaces affect efficiency. "Based on these complex simulations and empirical data, we believe that an efficiency of 32.5 % can realistically be achieved -- if we succeed to incorporate high quality perovskites with a band gap of 1.66 eV," says Jošt.
