Disclosed herein are a polymer solar cell, comprising a substrate, a first electrode, a hole injection layer, a photoactive layer, and a second electrode, characterized in that an electron-accepting layer is formed between the photoactive layer and the second electrode, and a method of manufacturing the polymer solar cell. The polymer solar cell comprises an electron-accepting layer between the photoactive layer and the second electrode, thereby assuring excellent power conversion efficiency. Furthermore, high power conversion efficiency can also be attained in a low-temperature thermal annealing process.

A dye-sensitized solar cell using an ion-bound oligomer complex is provided. The dye-sensitized solar cell comprises an electrolyte, comprising a first oligomer having a C5-30 heteroaryl group containing a nitrogen heteroatom as a basic functional group at both ends of the molecule, mixed with a second oligomer having an acidic functional group selected from among carboxylic acid, phosphoric acid, and sulfonic acid, at both ends of the molecule, to thus form a salt, which then leads to an ion-bound oligomer complex that constitutes the electrolyte. The solar cell exhibits excellent mechanical properties, can be manufactured conveniently, and can have a high energy conversion efficiency.
摘要:
Disclosed herein is a method for modifying the surface of a counter electrode. According to the method, the surface modification is achieved by treating the surface of a counter electrode with a polyethylene glycol derivative having a pendant group at one end. Also disclosed is a counter electrode whose surface is modified by the method. The electron transfer rate at the interface between the counter electrode and an electrolyte layer of a photovoltaic device is increased and the affinity of the counter electrode for the electrolyte layer is improved, resulting in an improvement in the power conversion efficiency of the photovoltaic device.
