Perovskite solar cells (PSC) have emerged as a promising photovoltaic technology in lab scale with a short time of research due to their high power conversion efficiency, simple device fabrication, all solid-state structure and the possibility to ingrate the traditional device into fiber format. In this work, a three-dimensional (3D) perovskite solar cell is demonstrated using functionalized carbon nanotube yarn (CNT) as both cathode and anode. TiO2 and 2,2,7,-7-tetrakis(N,N-di-p-methoxyphenylamine)-9,9'-spirobifluorene (Spiro-OMeTAD) are used as the electron transporting and hole transporting material respectively. The TiO2 oxide layer is deposited on the top of the twisted carbon nanotube yarn and annealed with TiCl4 to get the uniform electron transport layer. A dip coating process is employed to produce a uniform perovskite layer on top of the TiO2 oxide layer. Platinized carbon nanotube yarn is wrapped around on the top of the hole transporting layer and serves as the counter electrode. Under AM 1.5 100mWcm–2 illumination, a maximum power conversion efficiency (PCE) of 0.631% achieved with a high open current voltage (VOC) of 0.825V. This three-dimensional all solid state perovskite solar cell shows a promising prospect in portable and wearable textile electronics.
