    • According to our model one can argue that increased GB density (by reduced grain size) is beneficial. However, depleted/inverted GBs, ending at the cells' junction, would limit the photovoltage of the cell due to reduced junction barrier height in the depleted volume adjacent to the inverted GBs. Also, as the grains are isotropic in high efficiency CdTe cells, holes would have to cross some GB barriers to arrive at the back contact. Therefore, grain size should be optimized.

    • We note that, especially in the last one and a half decades, PX CdTe/ CdS solar cells were extensively empirically optimized for improved performance, while the problems encountered in improving single-crystal CdTe/CdS cells led to a decline in research with them. Irrespective of that, the difficulty in growing high PV quality single CdTe crystals will always limit the achievable efficiency of single-crystal cells.

    • The underlying concept here is profoundly different from that of devices whose function relies on the presence of structural defects (e.g., Varistors).
