This application discloses a solar cell, a photovoltaic device, an electrical appliance, and a power generation device. The solar cell includes at least a first light-absorbing layer and a hole transport layer, wherein the hole transport layer comprises polythiophene derivative molecules. The polythiophene derivative molecules possess good molecular arrangement and hole transport capability. The ester groups in the polythiophene derivative molecules can modulate the HOMO energy levels of the material without disrupting the molecular arrangement of the polythiophene derivative itself, thereby better matching the molecular energy levels of the hole transport layer and the first light-absorbing layer, thus improving the photoelectric conversion efficiency of the solar cell.

The invention discloses a carbon quantum dot photosensitizer, an extracellular vesicle prepared from the carbon quantum dot photosensitizer and application of the carbon quantum dot photosensitizer. The carbon quantum dot photosensitizer is prepared by a method comprising the following steps: uniformly dispersing a polythiophene derivative in a sodium hydroxide aqueous solution to obtain a solution A; heating the solution A for reaction; and after the reaction is finished, cooling to room temperature, taking out the solution, and filtering and dialyzing to obtain the carbon quantum dot photosensitizer. According to the technical scheme, the problems that extracellular vesicles are complex and tedious in preparation and difficult in mass production are solved, and the method is simple in process, good in universality, low in time consumption and low in cost.
