Although the cost of photovoltaics has dropped remarkably over the last few years, increasing the rate of uptake remains a priority. Low-cost thin-film absorber materials which can be produced using wide-area deposition processes have the potential to dramatically reduce the cost of photovoltaics even further. Development of effective oxide-based absorbers could enable the facile construction of robust, stable and very low-cost devices which could be deposited using existing industrially applicable wide-area deposition techniques. Significant research effort has gone into the development of p-type metal oxides, both as absorbers and as transparent contacts, but primarily due to the electronic properties typical of most metal oxides minimal success has so far been achieved. This project therefore aims to identify and optimise n-type oxide absorber materials, with an additional focus on Earth-abundance of the constituent elements. Materials development will be carried out using a unique combinatorial sputter deposition process allowing for rapid exploration of the compositional space and providing an effective means for easy identification of optimum materials parameters.

尽管过去几年光伏发电的成本显着下降，但提高采用率仍然是首要任务。可以使用大面积沉积工艺生产的低成本薄膜吸收材料有可能进一步大幅降低光伏成本。开发有效的氧化物吸收剂可以轻松构建坚固、稳定且成本非常低的器件，这些器件可以使用现有的工业适用的广域沉积技术进行沉积。人们在 p 型金属氧化物（既作为吸收剂又作为透明触点）的开发方面投入了大量的研究工作，但主要由于大多数金属氧化物的典型电子特性，迄今为止取得的成功很小。因此，该项目旨在识别和优化 n 型氧化物吸收材料，同时重点关注组成元素的地球丰度。材料开发将使用独特的组合溅射沉积工艺进行，可以快速探索成分空间，并提供一种有效的方法来轻松识别最佳材料参数。
