CPV Solar Concentrator Project

Building on the experience of semiconductor test equipment that ensures product reliability, Electron Test has plans of developing a CPV multi-junction solar cell module technology and a state-of-the-art parabolic solar concentrator.

Concentrating photovoltaic (CPV) technology uses optics such as lenses or curved mirrors to concentrate a large amount of sunlight onto a small area of solar photovoltaic (PV) cells to generate electricity.

CPV Performance for Electricity Production

Conventional solar power tower steam engine efficiency is only 14% and the average PV panel efficiency has 15%. Electron Test Equipment intention is to utilize CPV multi-junction solar cells (up to 46% efficiency) and build a receiver and solar concentrator dish that will generate 20 KW of electricity from light focused on the CPV cells.

The Challenge of Light Uniformity

In order to ensure uniformity of the light pattern reflected from the parabolic mirror, we need to have optics in place to guarantee an even light distribution. A solution to the problem would be utilizing a “Light Lens” to correct any imperfection of reflected light and concentrate the light on the CPV multi-junction cell receiver.

Unlike convention Fresnel lens CPV systems that require a Fresnel lens for each CPV solar cell, only one Light Lens is needed for the entire CPV receiver module. The expectation is to generate 20kW of electricity from one 20X20cm CPV receiver.
