Simultaneous high crystallinity and optical absorptance in hyperdoped black silicon using nanosecond laser annealing

Journal Article

Hyperdoped black siliconfabricated with femtosecond laserirradiation has attracted interest for applications in infrared photodetectors and intermediate band photovoltaics due to its sub-bandgap optical absorptance and light-trapping surface. However...

From black silicon to photovoltaic cells, using short pulse lasers

Conference Paper

Laser created Black Silicon has been developed since 1998 at Harvard University. The unique optical and semiconducting properties of the black silicon first lead to interesting applications for sensors (photodetectors, thermal imaging cameras…). Other...

Black silicon for photovoltaic cells: towards a high-efficiency silicon solar cell

Conference Paper

Laser-created Black Silicon has been developed since 1998 at Harvard University. The unique optical and semiconducting properties of black silicon first led to interesting applications for sensors (photodetectors, thermal imaging cameras, etc.) Other...

Luminescence of black silicon

Journal Article

Room temperature visible and near-infrared photoluminescence from black silicon has been observed. The black silicon is manufactured by shining femtosecond laser pulses on silicon wafers in air, which were later annealed in vacuum. The photoluminescence...
