This paper deals with the suitability of Fresnel lenses of imaging and nonimaging designs for solar energy concentration. The paper's scope is the review of long known, and recently developed Fresnel lenses, and the analyes of their characteristics for utilization as solar concentrators, putting an emphasis on a lens designed by the authors. Nonimaging optics are presented as o ering the possib...

The biological reduction of CO2 driven by sunlight via photosynthesis is a crucial process for life on earth. However, the conversion efficiency of solar energy to biomass by natural photosynthesis is low. This translates in bioproduction processes relying on natural photosynthesis that are inefficient energetically. Recently, hybrid photosynthetic technologies with the potential of significant...

The importance of solar energy can never be over-emphasized. Photovoltaic conversion is the most convenient method for harnessing energy. demand electricity has been increasing in this power hungry world. This challenged existing technology and motivated researchers to find innovative solutions. High cost high have always highlighted context photovoltaics. Due cost, during initial period, cells...
