Increases in wafer size are one recent technological development that demonstrates the accelerating rate of change currently underway in the solar manufacturing industry. In mid 2019, Zhonghuan Semiconductor very publicly pushed for wafer sizes to increase to 210mm. And while doubts linger as to whether a shift to such a large cell format is feasible, …
