Multilayer, microscale solar cells enable ultra-high efficiency power generation
Researchers at the University of Illinois at Urbana-Champaign use a printing process to assemble tiny cells into multilayer stacks for extraordinary levels of photovoltaic conversion efficiency.

""The strategy involves high-speed, printing-based manipulation of thin, microscale solar cells and new interface materials to bond them into multilayer stacks," Rogers said. "Quadruple-junction, four-terminal solar cells that we can build in this way have individually measured efficiencies of 43.9 percent.""
Imagine a standard sized solar panel of today that puts out about 250 watts, being able to put out somewhere around 630 watts. A 500 square foot panel array on one's roof could produce somewhere around 20KW peak instead of 8KW peak. All that's needed is a cheap, long lasting battery pack to capture the generated power.
