Description Besides cost, the most fundamental issue in assessing photovoltaic solar cells is efficiency. The benefits of single-junction solar cells are easier to manufacture, simpler and less expensive to make. However, they are less efficient than multi-junction solar cells. But when different semiconductors are stacked in layers to create multiple junctions, the atoms in the lower layers must not be blocked by the atoms in the upper layers or the sunlight passes by them instead of striking them. That means higher efficiency multi-junction solar cells are difficult to make. From the periodic table, group III-V and group II-VI produce the alloys of direct band-gap semiconductor. If group V anions are partially replaced with nitrogen atom or group VI element is partially replaced with oxygen atom then new semiconductor material is produced that respond to a wider spectrum of frequencies within sunlight. It will make single-junction multiple band-gap solar cell which is more efficient and less expensive to manufacture.
