Can black silicon be used in solar cells?

This might lead to both an increase in efficiency and a reduction in the manufacturing costs of solar cells. However, all previous attempts to integrate black silicon into solar cells have resulted in cell efficiencies well below 20% due to the increased charge carrier recombination at the nanostructured surface.

Can a conformal alumina film solve surface recombination in black silicon solar cells?

Here, we show that a conformal alumina film can solve the issue of surface recombination in black silicon solar cells by providing excellent chemical and electrical passivation.

Can BSI be used as an anti-reflection coating in solar cells?

The utilization of BSi as an anti-reflection coating in solar cells is then critically examined and appraised, based upon strategies towards higher efficiency renewable solar energy modules. Methods of incorporating BSi in advanced solar cell architectures and the production of ultra-thin and flexible BSi wafers are also surveyed.

Are B-Si solar cells recombinated?

Previous b-Si solar cell results have been limited to those from conventional front-side aluminium back surface field (Al-BSF) structures or ultrathin back-contacted cells 13, probably because these structures are less sensitive to front surface recombination.

Can black silicon reduce front-surface reflection in photovoltaic devices?

The nanostructuring of silicon surfaces—known as black silicon—is a promising approach to eliminate front-surface reflection in photovoltaic devices without the need for a conventional antireflection coating. This might lead to both an increase in efficiency and a reduction in the manufacturing costs of solar cells.

Is black silicon a good material for photovoltaics?

Black silicon would also appear to be an ideal material for photovoltaics due to its outstanding light management properties under the solar spectrum. In addition to boosting efficiency, b-Si can provide significant savings in manufacturing costs as there is no need to deposit a separate antireflection coating.
