                            分子石墨烯架构助力有机太阳能电池

                            中国粉体网讯    为了更好地为新能源领域的科研工作者服务,小编整理汇总过去一周世界范围内新能源材料研究的最新成果,以期能够为各位提供最新的知识,应对不断变化的世界。
                             
                              1、使用藻类生产生物燃料仍困难重重
                             
                              科学家们希望使用藻类生产生物燃料。然而这项技术还存在不足之处,一篇JRC发表的文章就列举出一些主要的难题,例如:藻类对营养物质的要求很高、在户外培育时很难保证选择的品种维持高的生产效率、生产藻类并转变为生物燃料的过程需要很高的能量投入,成本较高。而且,从实验室走向大规模生产也需要克服一些技术上的难题。
                             
                              2、从水桥到水电池
                             
                              “水桥”现象在十九世纪被人们发现,现在来自TU Graz and the Wetsus research Centre的科学家发现伴随水桥产生的还有带有电荷的水,并且这些电荷可以保持一段时间。
                             
                              放入阳极的水中会产生质子,这些质子通过水桥到达阴极,并在这里与羟基结合,因为质子的移动速度并不是很快,如果在实验过程中突然关闭电路,那么一个容器中的质子将会富余,另一个则会缺少质子,实验表明这些电荷可以存在一周时间。
                             
                              3、高电压低成本碲化镉太阳能电池
