Organic bulk heterojunction solar cells are a promising candidate for low-cost next-generation photovoltaic systems. However,carrier extraction limitations necessitate thin active layers that sacri...
Nanophotonic light-trapping theory for solar cells
Nanophotonic light-trapping theory solar cells
2011/8/10
Conventional light-trapping theory, based on a ray-optics approach, was developed for standard thick photovoltaic cells. The classical theory established an upper limit for possible absorption enhance...
We review the field of thin-film silicon solar cells with an active layer thickness of a few micrometers. These technologies can potentially lead to low cost through lower material costs than conventi...
Wafer Surface Charge Reversal as a Method of Simplifying Nanosphere Lithography for Reactive Ion Etch Texturing of Solar Cells
Simplifying Nanosphere Lithography Solar Cells
2008/10/30
A simplified nanosphere lithography process has been developed which allows fast and low-waste maskings of Si surfaces for subsequent reactive ion etching (RIE) texturing. Initially, a positive surfac...
