SUNNYVALE, Calif. -- SunPower Corp., a Silicon Valley-based subsidiary of Cypress Semiconductor Corp. (NYSE:CY), today announced the discovery of a new performance effect observed in high efficiency silicon solar cells. This new effect, called "surface polarization," creates the non-destructive and reversible accumulation of static charge on the surface of high-efficiency solar cells such as the company's all-back-contact A-300.
Surface polarization occurs when minute amounts of electrical current leak through the face of the solar cell and accumulate on the surface. Current leakage of this sort is present in all solar systems but will accumulate or dissipate on ...
