Abstract. The field of concentrated photovoltaics (CPV) has met some remarkable advances in recent years. The continuous increase in conversion efficiency of multijunction solar cells and new advancements in optics have led to new demands and opportunities for optical design in CPV. This paper is a mini-review on current requirements for CPV optical design, and it presents some of the main trends in recent years on CPV systems architecture. © The Authors.

“…In this way, the concentration is reduced, the acceptance angle is maintained, and relative electrical efficiency is boosted. The proof-of-concept concentrator CFK was developed, 48 and a relative efficiency increase of about 6.0% was measured at 18.45 W∕cm 2 with C3MJ+ solar cells 43 (see Fig. 7).…”

“…Up to date, highest concentrator module efficiency is claimed by Amonix, the Californian concentrated photovoltaics (CPV) specialist, after the NREL measured its 35.9% module efficiency [64]. A single-cell FK module, a Kohler-type concentrator, demonstrated recently measured efficiency values in the same range of 35.3-35.9% (36.00% maximum peak efficiency) [65].…”

We demonstrate high efficiency triple junction solar cells with submillimeter dimensions in an all-back-contact architecture. 550 × 550 μm2 cells flash at 41.3% efficiency under the air mass 1.5 direct normal spectrum at 50 W/cm2 at 25 °C. Compared to standard size production cells, the micro cells have reduced performance at 1-sun due to perimeter recombination, but the performance gap closes at higher concentrations. Micro cells integrated with lens arrays were tested on-sun with an efficiency of 34.7%. All-back-contact architecture and submillimeter dimensions are advantageous for module integration and heat dissipation, allowing for high-performance, compact, lightweight, and cost-effective concentrated photovoltaic modules.
