Hole-Selective Electron-Blocking Copper Oxide Contact for Silicon Solar Cells

Metal-oxide/silicon carrier-selective heterojunctions 5 be a low-cost high-efficiency alternative to conventional silicon solar cells. Here, a passivated Si/cuprous oxide (Cu$_2$O) hole-selective heterojunction with high open-circuit voltage (VOC) is …

A 12% Efficient Silicon/PEDOT:PSS Heterojunction Solar Cell Fabricated at <100 $^i̧rc$C

Solar cells based on a heterojunction between crystalline silicon and the organic polymer PEDOT:PSS were fabricated at temperatures textless;100 °C by spin coating. The Si/PEDOT interface blocks electrons in n-type silicon from moving to the anode …

Hole-blocking crystalline-silicon/titanium-oxide heterojunction with very low interface recombination velocity

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 …

Silicon surface passivation by an organic overlayer of 9,10-phenanthrenequinone

Reduction of minority carrier recombination at silicon surfaces and contacts using organic heterojunctions
