Abstract

original image

A flexible, dye-sensitized solar cell based on low-cost metal fibers as the substrates is designed. This cell provides a breakthrough on the traditional sandwich-type flat-cell structure. It has good flexibility even without a transparent conductive oxide. Moreover, the new solar cell can generate electric power with illumination on in either side, and mass production is possible using weaving technology. At present, the efficiency of 1.50 cm2 of the solar-cell module under AM 1.5 G (100 mW cm−2) reaches 2.41%.
