HCPV, or High Concentrated Photovoltaics are third generation solar cells based on Gallium Arsenide that utilize almost the entire solar spectrum, potentially reaching 68% conversion in theory. As of now, HCPV can achieve a 42% conversion rate, much more efficient than Silicon’s 25% conversion rate and Silicon Thin Film, which can only convert at 15% efficiency.
HCPV is a mature technology that has been improved over twenty years. As of now, HCPV uses Fresnel Lenses to focus sunlight into the PV module and is also mounted on a dual-axis sun tracker that will tilt the HCPV towards the sun, prolonging the hours of PV functionality.
In contrast to normal PVs, HCPV is easier to maintain. If a cell is damaged, it can be individually replaced without removing the entire panel. Furthermore, the HCPV does not contain glass or brittle panels and does not require water to operate.
