Power conversion efficiency (PCE) of the perovskite solar cells (PSCs) has remarkably been
increased from 3.1% to 25.2%. The fast expansion of the PSCs has been along with the …

Polycrystalline optoelectronic materials are widely used for photoelectric signal conversion
and energy harvesting and play an irreplaceable role in the semiconductor field. As an …

We study the effects of a series of post-deposition ligand treatments on the
photoluminescence (PL) of polycrystalline methylammonium lead triiodide perovskite thin …

Conventional photovoltaic devices are currently made from relatively thick semiconductor
layers,~ 150 µm for silicon and 2–4 µm for Cu (In, Ga)(S, Se) 2, CdTe or III–V direct bandgap …

We report a systematic study of carrier dynamics in Al x Ga1–x As-passivated GaAs
nanowires. With passivation, the minority carrier diffusion length (L diff) increases from 30 to …

For cells near the radiative limit, optically limiting the angles of emitted light causes emitted
photons to be recycled back to the cell, leading to enhancement in voltage and efficiency …

Perimeter recombination is one of the causes identified for having a nonuniform luminescent
coupling effect in III-V multijunction solar cells. A potential solution could be the electrical …

Although there are individual reports on the efficiency enhancement methods in the form of
news articles, highlights and research papers in the literature; there is no article mentioning …

GaAs photovoltaics are promising candidates for indoor energy harvesting to power small-
scale (mm 2) electronics. This application has stringent requirements on dark current …

III-V semiconductor nanowires behave as optical antennae because of their shape
anisotropy and high refractive index. The antennae like behavior modifies the absorption …
