Innovative Materials for Multiple Junction OPVs and for Improved Light Management (MUJULIMA)
Start date: Jan 1, 2014, End date: Dec 31, 2016 PROJECT  FINISHED 

Solar photovoltaic (PV) technology is one of the fastest growing sustainable, renewable energy conversion technologies that can help meet the increasing global energy demands. Organic photovoltaic (OPV) technologies are particularly attractive due to their compatibility with low-cost roll-to-roll and printing processing at low temperatures on a wide variety of substrate materials and the lack of scarce or toxic materials rendering them environmentally friendly. OPVs can also benefit from a larger selection of functional materials as the required properties (high semi-conductor mobility, suitable band-gap, good intrinsic stability, good barrier properties, etc.) can be tuned by careful design and synthesis.Currently, the highest cell efficiencies reported in Europe for solution processed single (>9%), double (8.9%) and triple (9.6%) junction cells as well as the lowest water vapor transmission rates for transparent flexible barriers (WVTR 10-6 g/m2/day) were obtained by the partners of MUJULIMA. In this project we show how with new and innovative materials we will increase the module efficiencies (larger than 15%) and outdoor stability to make OPVs a commercially competitive viable technology.The general objective of MUJULIMA is to develop high performance commercially competitive materials with excellent intrinsic stabilities for the cost-effective production of double and triple junction OPVs, for improved light management and for enhanced outdoor stability to achieve high module efficiencies (larger than 15%) and lifetime (larger than 10 years).The innovative materials and technologies developed within MUJULIMA will be demonstrated via three applications powered by OPVs: (a) in-house electrical automation devices, (b) urban furniture, and (c) flexible OPV modules on bus roof.
