聚苯乙烯球用于模板TiO 2与单层的300 nm的威尔斯，其中填充有PbS量子点，以形成异质结太阳能电池。多孔阱器件的效率为5.7%，而简单平面结的效率仅为3.2%。使用光吸收和光电流瞬态衰减测量的组合，我们确定，性能增强来自增强的光吸收和增加的载流子寿命的组合。
Polystyrene spheres are used to template TiO2 with a single layer of 300 nm wells which are infilled with PbS quantum dots to form a heterojunction solar cell. The porous well device has an efficiency of 5.7% while the simple planar junction is limited to 3.2%. Using a combination of optical absorption and photocurrent transient decay measurement we determined that the performance enhancement comes from a combination of enhanced optical absorption and increased carrier lifetime.
