Problems solved by technology

Since the phycoerythrin dye-sensitized layer mostly exists in liquid form, it is difficult to apply
However, if the solid phycoerythrin biological dye-sensitized layer is used, it will cause problems such as protein denaturation, resulting in low photoelectric conversion efficiency of the assembled dye-sensitized cells.

Description

technical field [0001] The invention belongs to the field of chemistry, and specifically relates to a composite gel containing phycoerythrin, a preparation method and application thereof, more specifically a composite gel of phycoerythrin / collagen / carboxylated carbon nanotube / polyacrylamide, Preparation method and application. Background technique [0002] Solar energy is the most abundant sustainable energy resource, and the surface of the earth receives about 4×10 24 J Solar. Photosynthesis in nature has been a typical application of solar energy for more than 350 million years. Biological processes are the largest-scale conversions of photon energy into Gibbs free energy. Since the 1990s, the invention of solar cells has promoted the research and application of scientists using biological macromolecules to assemble dye-sensitized solar cells. The characteristics of low cost, environmental friendliness and simple fabrication make dye-sensitized cells have good applicat...
