Role of Majority and Minority Carrier Barriers Silicon/Organic Hybrid Heterojunction Solar Cells

A hybrid approach to solar cells is demonstrated in which a silicon p–n junction, used in conventional silicon-based photovoltaics, is replaced by a room-temperature fabricated silicon/organic heterojunction. The unique advantage of silicon/organic heterojunction is that it exploits the cost advantage of organic semiconductors and the performance advantages of silicon to enable potentially low-cost, efficient solar cells.
