We report the fabrication and measurement of solar cells approaching a power conversion efficiency of 3.2% using a low band gap conjugated polymer poly[2,6-(4,4-bis-(2-ethylhexyl)-4H-cyclopenta[2,1-b;3,4-b']dithiophene)-alt-4,7-(2,1,3-benzothiadiazole)] and CdSe nanoparticles. These devices exhibit an external quantum efficiency (EQE) of >30% in a broad range of 350-800 nm with a maximum EQE of 55% in a range of 630-720 nm. We also present certified device efficiencies of 3.13% under AM 1.5 illumination.
我们报告了使用低带隙共轭聚合物聚[2,6-(4,4-双-(2-乙基己基)-4H-环戊[2,1-b;3,4-b']二噻吩)-交替-4,7-(2,1,3-苯并噻二唑)]和 CdSe 纳米粒子制备并测量了接近 3.2%功率转换效率的太阳能电池。这些器件在 350-800nm 的宽范围内表现出 >30%的外量子效率(EQE)，在 630-720nm 的范围内最大 EQE 为 55%。我们还在 AM 1.5 照明下提供了经过认证的 3.13%的器件效率。
