Flexible Solar Cells: Ultralight High‐Efficiency Flexible InGaP/(In)GaAs Tandem Solar Cells on Plastic (Adv. Energy Mater. 5/2013)

Ultralight high-efficiency flexible solar cells can enable new applications in consumer electronics and space satellites. Davood Shahrjerdi and co-workers present on page 566 a novel layer transfer approach, called controlled spalling, for making large-area flexible III-V tandem solar cells on plastic with conversion efficiency of >28% under one sun intensity. This flexible solar cell exhibits a remarkably high specific power, thus lending itself to portable applications requiring high-efficiency and lightweight flexible photovoltaic modules.
