Why Monocrystalline solar wafers are increasing in dimensions & size recently?

Why are monocrystalline wafers increasing in size?
Traditionally, monocrystalline silicon wafers before 2010 were classified as small-size with 125mm x 125mm width (164mm silicon ingot diameter) and only a small number at 156mm x 156mm (200mm silicon ingot diameter), which had been the dominant ingot size in the semiconductor industry until leading companies adopted 300mm diameter ingots

Monsoon Wang, Director of Product Marketing at LONGi Solar told that the wafer size change is occurring faster than many people realize.
According to PV-Tech, the solar industry was undergoing major technology changes, notably the shift to PERC (Passivated Emitter Rear Cell) and more recently the migration away from multicrystalline wafers to monocrystalline.
These developments have led to the mass production of high-efficiency p-Type mono-PERC, bifacial cells, half-cut and shingled technologies for modules, which are available in double-glass, multi-busbar, and half-cell module configurations. All pushing high-efficiency products into the mainstream high-volume markets.
