The design and realization of large-scale patterned organic solar cells in series and parallel configurations

A patterned method was proposed to realize large area fabrication of organic solar cells (OSCs) in series and parallel configurations. Series and parallel configurations of OSCs on ITO glass were designed and studied. Large open circuit voltage (V-OC) was achieved in series OSCs, while the high short-circuit current (I-SC) was achieved by using the parallel structure. A photovoltaic device composed of eight ITO/NiO/P3HT:PCBM/Al OSCs in series connection with area of 5 x 4 cm(2), V-OC of 4.35 V. I-SC of 1.59 mA and power conversion efficiency of 2.08% was achieved. This device succeeded in driving a group of 11 light emitting diodes. In addition, this patterned method a device with V-OC of 1.5 V and I-SC of 18 mA succeeded in driving a small motor.
