40% EfficientSolar Cells

Scientists at Spectrolab, Inc., a subsidiary of Boeing have built solar cells capable of working at 40% efficiency. "These results are particularly encouraging since they were achieved using a new class of metamorphic semiconductor materials, allowing much greater freedom in multijunction cell design for optimal conversion of the solar spectrum," Dr. Richard R. King, principal investigator of the high efficiency solar cell research and development effort, told PhysOrg.com. "The excellent performance of these materials hints at still higher efficiency in future solar cells." A multi-junction approach allows the cell to utilize more of the spectrum which hits it.
