| Research Abstract |
pn homojunction was fabridated in single fullerene film by doping of donor (cesium carbonate) and acceptor (molybdenum oxide). i-layer in pin junction was fabricated by the cross doping technique in fullerene films. Energetic structure of i-layer was designed based on the ratio of donor and acceptor dopants. pin organic solar cells using fullerene:sexithiophene codeposited layer showed the efficiency of 1.6% and its tandem cell showed the efficiency of 2.4%. Thus, the cross-doping technique was successfully established.
