Efficiency record for black silicon solar cells jumps to 22%
May 20, 2015
Universitat Politècnica de Catalunya & Aalto University’s researchers have obtained the record-breaking efficiency of 22.1% on nanostructured silicon solar cells.
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.
Due to the ability of black cells to capture solar radiation from low angles, they generate more electricity already over the duration of one day as compared to the traditional cells. This is an advantage particularly in Finland, where the sun shines from a low angle for a large part of the year.
