Abstract

Transparent quasi-interdigitated electrodes (t-QIDEs) were produced by replacing the opaque components of existing QIDEs with indium tin oxide (ITO). We demonstrate their application in the first semitransparent back-contact perovskite solar cell. A device with a V OC of 0.88 V and a J SC of 5.6 mA cm -2 produced a modest 1.7% efficiency. The use of ITO allows for illumination of the device from front and rear sides, resembling a bifacial solar cell, both of which yield comparable efficiencies. Coupled optoelectronic simulations reveal this architecture may achieve power conversion efficiencies of up to 11.5% and 13.3% when illuminated from the front and rear side, respectively, using a realistic quality of perovskite material.
