Since the charge-transport layers of photovoltaic cells (PEDOT:PSS, transition metal oxides, Spiro-OMeTAD, etc.) do not differ in high electrical conductivity, it is necessary to find ways to increase the efficiency of the cells.
For photovoltaic applications, studies of their optical properties, stability, and electrical conductivity are of greatest interest. However, the PEDOT:PSS transport layers, when used in photovoltaic cells, have a high electrical resistance, which prevents solar cells from increasing their efficiency.
Thus, the proposed liquid-phase methods for creating PEDOT:PSS composite layers using amines make it possible to improve their conductivity in a simple way and thereby increase the efficiency of photovoltaic cells. 4. Conclusions
If the semiconductor's bandgap matches the wavelengths of light shining on the PV cell, then that cell can efficiently make use of all the available energy. Learn more below about the most commonly-used semiconductor materials for PV cells.
