通过设备外形的小型化来改善卷对卷加工的聚合物太阳能电池模块的性能。使用包括柔性版印刷、狭缝模头涂布和旋转丝网印刷的全卷对卷处理来制备器件，以在ITO-PET基底上产生5 mm宽的ZnO、P3 HT：[60/70] PCBM、PEDOT：PSS和银线。线间隔1 mm，通过在两侧使用压敏粘合剂和多层阻隔材料使用卷对卷层压进行封装来完成器件，所述多层阻隔材料具有截止波长为390 nm的UV过滤器，氧气和水蒸气透过率分别为0.01 cm（3）m（-2）bar（-1）day（-1）和0.04 gm（-2）day（-1）。最后的模块包括16个串联连接的电池。基于V-oc必须大于7.2V的标准，技术产率为89%。这组模块分别给出8.47 +/-0.41V，-23.20 +/-4.10mA，35.4 +/- 2.8%和1.96 +/- 0.34%，基于P3 HT的模块：[60] PCBM。每次运行共准备了1960个模块，基于P3 HT：[70] PCBM的器件达到的最佳功率转换率为2.75%。太阳能电池模块用于演示完全使用柔性电子技术的小型灯的完整制造。该太阳能电池模块通过阻塞二极管对聚合物锂离子电池充电。整个过程是完全自动化的，并展示了聚合物太阳能电池在柔性和印刷电子产品中的能力。最后比较了OPV和晶体硅太阳能电池的学习曲线的每瓦成本峰值和累积瓦峰值。OPV作为一种技术被发现具有显著陡峭的学习
The improvement of the performance of roll-to-roll processed polymer solar cell modules through miniaturization of the device outline is described. The devices were prepared using full roll-to-roll processing comprising flexographic printing, slot-die coating and rotary screen printing to create 5 mm wide lines of ZnO, P3HT:[60/70] PCBM, PEDOT:PSS and silver on an ITO-PET substrate. The lines were spaced by 1 mm and the devices were completed by encapsulation using roll-to-roll lamination on both sides using a pressure sensitive adhesive and a multilayered barrier material having a UV-filter with a cutoff at 390nm, oxygen and water vapor transmission rates of respectively 0.01 cm(3) m(-2) bar(-1) day(-1) and 0.04 gm(-2) day(-1). The final modules comprised 16 serially connected cells. The technical yield was 89% based on the criterion that the V-oc had to be larger than 7.2 V. This set of modules gave respectively a voltage, current, fill factor and power conversion efficiency of 8.47 +/- 0.41 V, -23.20 +/- 4.10 mA, 35.4 +/- 2.8% and 1.96 +/- 0.34% in the case of modules based on P3HT:[60] PCBM. A total of 1960 modules were prepared for each run and the best power conversion reached was 2.75% for devices based on P3HT:[70] PCBM. The solar cell modules were used to demonstrate the complete manufacture of a small lamp entirely using techniques of flexible electronics. The solar cell module was used to charge a polymer lithium ion battery through a blocking diode. The entire process was fully automated and demonstrates the capacity of polymer solar cells in the context of flexible and printed electronics. Finally a comparison was made between the learning curve for OPV and crystalline silicon solar cells in terms of the cost per watt peak and the cumulative watt peak. OPV as a technology was found to have a significantly steeper learning
