Topic:Miniaturization, Hybridization and Tracking Integration: New Directions for CPV

Since its boom years in the middle of the last decade, CPV has fallen out of favor in the face of stiff competition from cheap silicon PV. Recently, CPV manufacturers and researchers have moved away from trying to compete directly with Si on cost, and instead have turned towards adapting or modifying CPV concepts to provide additional functionalities that are not offered by conventional PV. The broad range of proposed applications, including HPV systems for rooftops, building integration, agricultural settings and thermal-electric “co-generation,” typically rely on a combination of three concepts: miniaturization or “micro-CPV,” which allows smaller, lighter modules to be designed, relying on manufacturing techniques from the microelectronics industry; spectrum splitting or hybridization whereby the solar resource is divided between two or more different applications; and tracking integration, which aims to transform both the practical and the economic considerations around CPV by including sun-tracking mechanisms inside the CPV module itself, rather than relying on external trackers. This presentation will discuss the principles behind these three concepts that together form the foundation of the “new CPV,” and offer a survey of experimental CPV systems that utilize them. It aims to provide an understanding of the current advanced concepts and research directions, being pursued primarily in the academic context, that seek to keep CP relevant in the cheap PV age.
