High Specific Power Photovoltaics: Increasing Markets by Decreasing Package Weight


We will discuss how high specific power (power-to-weight ratio) PV may generate value beyond the typical “value triad” of efficiency, cost, and reliability that dominates the utility market and how this value might be generated in a largely technology agnostic manner. By examining historical market trends in PV and comparing these to potential markets together with their requirements, we can establish pathways for new technologies to emerge with immediate impact in protected markets to gain experience before transitioning to the highly competitive utility-scale market. We will examine the driving factors to achieve high specific power including cell efficiency, packaging, and interconnect contributions. Tradeoffs and design considerations that researchers must consider will be discussed.
