NOVELTY - An organic solar cell has a first electrode and a second electrode formed on a substrate. An electrical hole is formed between the first and the second electrodes. An electron-receptor and a photoactive layer are formed with triphenylene compounds.    USE - Organic solar cell.    DETAILED DESCRIPTION - An organic solar cell has a first electrode and a second electrode formed on a substrate. An electrical hole is formed between the first electrode and the second electrode. An electron-receptor and a photoactive layer are formed with triphenylene compounds.
