| Abstract
| - A nanostructured photovoltaic device was built with porous n-type TiO2, a thin coating of CdS absorber, and a transparent p-type CuSCN filling the pores. The cell showed an internal quantum efficiency of ∼100% and a cell efficiency of >1%, which was a clear demonstration of the potentiality for a new type of solar cell.
- Nanostructured photovoltaic devices were fabricated using a porous n-type TiO2 film, a thin layer ofCdS acting as the absorber, and a transparent p-type CuSCN filling the pores. The cell showed an internalquantum efficiency of ∼100% and significant cell efficiency of 1.3% at 1 sun, as well as high photovoltage(0.85 V) and a filling factor of 0.65. Though the cell concept was already proposed by others, this cellclearly shows a significant performance and it demonstrates the potentiality of such cells made with verythin absorber layers (<10−20 nm) and largely structured porous films (roughness factor >100). Descriptionof component characterization and explanation of identified issues are presented.
