Microcell concentrating photovoltaics (µCPV) have the potential to improve performance and reduce the cost of solar power in space. Here, we introduce an ultracompact V-cone tailored edge ray (V-TERC) concentrator, rooted in nonimaging optics, which

Antireflection (AR) coatings with graded refractive index profiles approaching air offer unparalleled AR performance but lack a scalable fabrication process that would enable them to be used more widely in applications such as architecture and solar

Microcell concentrating photovoltaics are being explored for space photovoltaic power due to their compact, monolithic design and potential to both reduce III-V cost and improve performance. This paper introduces a new ultra-compact and high flux mic

Plastic optics are used in an ever-expanding range of applications and yet a durable, high performance antireflection (AR) coating remains elusive for this material class. Here, we introduce a sacrificial porogen approach to produce ultralow refracti

Optical concentration can improve the efficiency and reduce the cost of photovoltaic power but has traditionally been too bulky, massive, and unreliable for use in space. Here, we explore a new ultra-compact and low-mass microcell concentrating photo

Diluting small molecule organic semiconductor hole transport materials with Teflon AF (TAF) dramatically increases their thermal/morphological stability while counterintuitively also increasing the current density in hole-only diodes. Here, we explor

Concentrating photovoltaics (CPV) can increase the efficiency and reduce the cost of photovoltaic power in space. We introduce a new monolithic, ultrathin, and lightweight CPV paradigm based on a transfer-printed microscale solar cell array. In our r
