"team has already increased the transparency of the module to 40%. They believe they can approach 60% transparency... They’re also working on bumping up the efficiency from the 10% achieved in the reported semitransparent modules, closer to the 15% believed to be possible at high transparency. Because the materials can be prepared as liquids, the manufacturing costs are expected to be relatively low"
