Abstract Organic photovoltaics (OPV) with junction controlled structure are prepared by the evaporative spray deposition using ultra-diluted solution (ESDUS) method with different donor polymer(p) and acceptor fullerene(n) ratio solution. In order to demonstrate the ideal junction, we fabricate the polymer solar cells with single junction(p/n), pin-layered junction (pin) or bulk-heterojunction (BHJ) active layer. The photovoltaic performance is dramatically varied with its junction. And the pin junction has best performance under the sunlight due to its good carrier generation and transport. And also we investigated the temperature dependence of the active layer morphologies at each substrate temperature 60 − 160 °C during its spray-depositing. The domain of active layer became smaller with increasing substrate temperature. The pin-layered cell sprayed at 120 °C gives best photovoltaic performance. Thus, ESDUS enables us to control the junction and morphologies of active layer.

使用超稀溶液（ESDUS）蒸发喷涂沉积制备的聚合物半导体薄膜的特性：在聚合物光伏电池中的应用

摘要 使用超稀溶液（ESDUS）法，用不同的供体聚合物（p）和受体富勒烯（n）比溶液通过蒸发喷涂沉积制备具有结控制结构的有机光伏（OPV）。为了证明理想的结，我们制造了具有单结（p/n）、针层结（pin）或体异质结（BHJ）活性层的聚合物太阳能电池。光伏性能随其结而显着变化。并且pin结由于其良好的载流子生成和传输在阳光下具有最佳性能。并且我们还研究了在喷射沉积过程中在每个基板温度 60 - 160 °C 下有源层形态的温度依赖性。随着衬底温度的升高，有源层的畴变小。在 120 °C 下喷涂的针层电池可提供最佳光伏性能。因此，ESDUS 使我们能够控制有源层的结和形态。
