Desert Module: Higher Yields through Optimized Design

How can module components and module design be adapted to the stress factors that are particularly prevalent in desert environments, thereby increasing the yield and lifetime of the modules? Fraunhofer researcher Hamed Hanifi has investigated this question. His results have now been published in an article in Applied Energy.
