Low‐intensity high‐temperature (LIHT) solar cells are needed for extended photovoltaic power generation in both the lower atmosphere as well as at the surface of Venus. Double‐junction GaInP/GaAs solar cells that may be able to operate and surv

We report the design, fabrication, and characterization of silicon heterojunction microcells, a new type of photovoltaic cell that leverages high-efficiency bulk wafers in a microscale form factor, while also addressing the challenge of passivating m

Next generation space solar cells are required to be efficient, light and low cost. In order to GaAs-based devices keep playing a significant role in space the radiation performance needs to be increased to eliminate the required shielding and the co

We present a GaAs heterojunction solar cell that achieves 830mV Voc without any epitaxial processing or external doping on a bulk wafer and has an area of 10mm^2. The device consists of a bulk, n-type GaAs wafer with sulfur passivation, 10 nm of spun

The quantum efficiency of double hetero-junction light-emitting diodes (LEDs) can be significantly enhanced at low current density by tailoring the spatial profile of dopants to suppress Shockley-Read-Hall (SRH) recombination. To demonstrate this eff

We develop a new technique for transferring metal contacts to create ultrathin solar cells from 2D materials.
Two-dimensional transition metal dichalcogenides are promising candidates for ultrathin optoelectronic devices due to their high absorp

We demonstrate silicon heterojunction solar cells with microscale effectively transparent front contacts (ETCs) that redirect incoming light to the active area of the solar cell. Replacing standard contact electrodes by ETCs leads to an enhancement i

The efficiency of substrate-removed GaAs nanowire solar cells can be increased to over 32% by borrowing processes and materials from GaAs MOSFETs and perovskite photovoltaics. Photogenerated carriers fundamentally limit the performance of off-wafer h
