Altho binary materials are normally preferred due to synthesizability, ternary and tetra-nary bulk crystals offer an opportunity to improve on deficiencies.  An important aspects duue to geometry are:  * Depth of the p/n junction below the cell's surface  * Amount and distribution of dopant atoms on either side of the p/n junction  * Crystallinity and purity of crystals. Defect cause electrons and holes to recombine.
