博士 === 國防大學理工學院 === 國防科學研究所 === 100 === The energy crisis and global warming are issues and to-be-solved problems of world concern. Looking for sustainable energy is one of today's important issues. Photovoltaic (solar) energy conversion will provide a crucial part of future sustainable energy needs. The main issue the solar industry facing currently is how to reduce the cost of power generating system. The next-generation photovoltaics should aim not only at high efficiency but also low-cost per unit area. Various approaches include replacing expensive semiconductor material with low cost solar collectors and concentrators and the use of high efficiency smaller area photovoltaic devices. This study proposes the idea and underlying theory of optical holography and its applications in solar energy concentrations without the help of tracking system. Two improved devices of converting solar energy into electricity have been constructed. The first device consists of a hologram pairs with a holographic diffraction and a holographic optical element will concentrating the solar spectrum onto solar cells. The second ones consists of lenticular lens array and a hologram paired with a holographic collimation device and a holographic solar concentrator can concentrate the solar spectrum onto solar cells.
