Solar holography—A potential high efficiency green energy solution

Abstract

Two impediments that acted globally against the progress and popularity of solar electricity were low efficiency and high price of traditional Silicon photovoltaic (PV) panels. Though mass manufacturing and large scale competition between manufacturers have resulted in per Watt price of about 0.3–0.5 USD, low efficiency of these panels still remains as a major hurdle. Concentrator Photovoltaics (CPV) with spectral splitting ability gained worldwide research interest during the recent decades. This paper presents an overview of activities in this highly emerging green energy avenue, some of our work and future design possibilities of relevance.
