Current status of colloidal quantum-dot solar cells and their potential for ultra-high efficiency
Haibin WANG1, Takaya KUBO1
Colloidal quantum-dots can control the range of light absorption by adjusting the particle size, and a solid film of densely-packed colloidal quantum dots demonstrates semi-conductive characteristics. Therefore colloidal quantum-dots are likely to become a material for the next-generation solar cells created by low-temperature/solution processes. This article explains the latest efforts to create high-efficiency hetero-junction solar cells, comprised of wide-gap semiconductors and quantum dots. In addition, our research results regarding the photoelectric conversion properties of colloidal quantum dot/ZnO nanowire solar cells that operate in the infrared region will be introduced.
