Organic photovoltaic cells are characterized by low cost and easy large-area fabrication
.

Organic solar cells with a tandem stack configuration have outstanding advantages in achieving high photoelectric energy conversion efficiency (photovoltaic efficiency) due to the more efficient utilization of sunlight

Recently, Hou Jianhui, a researcher at the Laboratory of Polymer Physics and Chemistry, Institute of Chemistry, Chinese Academy of Sciences, discovered that in the process of electron beam evaporation of titanium dioxide, rutile-phase titanium dioxide can be converted into an amorphous film
.

The film is not only uniform and dense, but also has good acid resistance
