A stationary solar photovoltaic array module design, which constitutes four steps of optical concentrations of photovoltaic electric power generation systems. A compound parabolic concentrator (CPC) is mounted under a first and second optical concentrating fresnel lenses that concentrates the intensity of sunlight. Then the focused sunlight is further concentrated twenty times by the third optical concentrator CPC. The high mirror quality of CPC allows 98% of the reflected rays to be focused at the bottom of the CPC. At this point, the intensified sunlight is homogenized as it passes through a fourth optical concentrator glass lens, which with anti-reflection coating on the top of the glass lens' surface, incident on the multi-junction solar cell accomplish the fourth optical concentration for the photovoltaic electric energy conversion. |
