Since the absorption spectra of carbon quantum dots are mainly concentrated in the ultraviolet region and nearly transparent to visible light, a new concept of ultraviolet photovoltaic window is proposed using carbon quantum dots as a light absorber. The photovoltaic window can generate electricity without affecting indoor lighting and effectively block the entry of ultraviolet light. Cotton fiber as carbon precursor and urea as dopant are used to prepare green N-doped carbon quantum dots with blue fluorescence. Moreover, the amount of dopant and thickness of TiO₂ film have a great influence on the power conversion efficiency and transmittance of the photovoltaic window. The best efficiency of the photovoltaic window obtained is 0.614% and its average visible transmittance is also the best (37.2%) among the prepared photovoltaic windows. The construction of ultraviolet photovoltaic window successfully opens up a new application of carbon quantum dots in building-integrated photovoltaics.

基于绿色碳点的对可见光具有高透明度的紫外光伏窗

由于碳量子点的吸收光谱主要集中在紫外区，对可见光几乎是透明的，因此提出了以碳量子点作为光吸收剂的紫外光伏窗的新概念。光伏窗可以在不影响室内采光的情况下发电，并有效阻挡紫外线的进入。以棉纤维为碳前驱体，尿素为掺杂剂，制备具有蓝色荧光的绿色掺氮碳量子点。此外，TiO ₂的掺杂量和厚度薄膜对光伏窗的功率转换效率和透光率有很大影响。所得光伏窗的最佳效率为0.614%，平均可见光透射率也是制备的光伏窗中最好的（37.2%）。紫外光伏窗的构建成功开辟了碳量子点在光伏建筑一体化中的新应用。
