Seminarium Fizyki Ciała Stałego

From a few years, our group has been constructing and investigating solar cells based on bulk heterojunctions (BHJ). The BHJs are formed in the scale of nanometers as mixture of two compounds called donor and acceptor materials. Illumination causes excitation of electrons and holes. Due to difference in quantum levels between the two compounds, electrons go to the acceptor material and holes go to the donor material. Then the charge carriers are collected by electrodes supplying electric current and power.In the seminar I will explain how the BHJ works and present few interesting facts that we had found during our research. The organic solar cells are usually described in language used in organic chemistry. I plan to use terms more familiar to physicists working with classical, crystalline semiconductors, for example, "acceptor material" can be understood as n-type semiconductor.UwagaSeminarium w trybie HybrydowymFaculty of Physics room 0.06patrz instrukcja :instrukcja: (pdf file)AttentionThe seminar in the REMOTE modesee instruction :instruction: (pdf file)
