曼彻斯特大学的研究人员使用聚苯乙烯颗粒而不是昂贵的聚合物制造下一代太阳能电池，用其制造的太阳能电池板的性能更加稳定，而且价格更加便宜。此举将大大降低太阳能电池的生产制造成本，同时可以在能源价格上涨的时候，为社会公众提供更加低廉的电力能源。这项研究被发表在皇家化学学会的期刊Nanoscale上，研究主要阐述了曼彻斯特大学的科学家是如何使用绝缘聚苯乙烯凝胶微粒以此来达到降低成本的目的，与此同时进一步提高钙钛矿太阳能电池（PSCs）的稳定性。 钙钛矿太阳能电池是一种新型太阳能电池板，被世界经济论坛评为十大新兴技术之一。这是因为其功率转换效率有了前所未有的提高，而且每瓦特的成本也相对较低。目前，太阳能电池板在英国各地的房屋和建筑物中具有较高的普及率，但是其大规模地使用仍然受到高生产成本的阻碍。这些传统的光伏（PV）太阳能电池板利用硅来获取可以转化为能量的光，但它是一种昂贵的、能量密集的材料。最近的研究已经转向使用便宜的化合物钙钛矿（PSCs），作为代替硅的光收集层。 钙钛矿（PSCs）的电力转换效率现在正接近既定的太阳能光伏技术的同等水平，这需要几十年才能达到。所以，拥有着在更短的时间和较低的生产成本下实现更高效率的潜力， 由此看来，PSCs变得越来越具有商业吸引力。然而，目前的钙钛矿（PSCs）通常使用金属卤化物钙钛矿（OHP）作为光吸收剂，当其接触到水时，很容易发生降解。这使得他们的实际作用有限，尤其是在英国的气候条件下。这些空隙还依靠空穴传输层，它促进了阳光照射后电流的有效移动。但是，制造空穴运输有机材料是非常昂贵的，而且都缺乏长期稳定性。这就是我们要使用保温聚苯乙烯微凝胶颗粒的原因。
