德国布伦瑞克大学(University of Braunschweig)的科学家们开发出一种新型太阳能聚光器，可以将来自任何方向的光线集中在太阳能电池板上。研究人员表示，这一漏斗可以被调节至不同光波波长并被堆叠起来，能使整个光谱转换成电能。
太阳能聚光器是一种能将阳光光线集中在小面积上的一种透镜。由于大多数太阳能电池只适合在阳光直射的条件下工作，因此它未能在太阳能领域中被广泛采用。
但这一新型聚光器由一种随机取向的颜料构成，几乎可以从任何入射角度吸收光线，并将其映射在面向单一方向的组件上。在聚光过程中只有10%的损失。而实验表明，这一聚光器能吸收入射光的99%左右，光重定向量子效率大于80%。
科学家们预计，未来有可能将不同波幅的聚光器相互堆叠在一起，形成一个可以吸收整个光谱的聚光器。由于这些聚光器是由价格低廉、用途广泛的材料而制成，因而可以被开发成一种低本高效的太阳能电池助推器。
