Microlens array induced light absorption enhancement in polymer solar cells.
Over the last decade, polymer solar cells (PSCs) have attracted a lot of attention and highest power conversion efficiencies (PCE) are now close to 10%. Here we employ an optical structure - the microlens array (MLA) - to increase light absorption inside the active layer, and PCE of PSCs increased even for optimized devices. Normal incident light rays are refracted at the MLA and travel longer ...
متن کاملLight trapping design for low band-gap polymer solar cells.
We demonstrate numerically a 2-D nanostructured design for light trapping in a low band-gap polymer solar cell. Finite element method simulations are used to study the effect of varying nanostructure periodicity, height, and shape on active layer absorption. Maintaining a constant active layer thickness of 100 nm we observe an enhancement in solar absorption of almost 40% relative to a planar c...
متن کاملTransparent polymer solar cells employing a layered light-trapping architecture
Organic solar cells have unique properties that make them very attractive as a renewable energy source. Of particular interest are semi-transparent cells, which have the potential to be integrated into building façades yet not completely block light. However, making organic cells transparent limits the metal electrode thickness to a few nanometres, drastically reducing its reflectivity and the ...
متن کاملPolymer solar cells.
This article reviews the motivations for developing polymer-based photovoltaics and describes some of the material systems used. Current challenges are identified, and some recent developments in the field are outlined. In particular, recent work to image and control nanostructure in polymer-based solar cells is reviewed, and very recent progress is described using the unique properties of orga...
متن کاملPolymer solar cells
nature photonics | VOL 6 | MARCH 2012 | www.nature.com/naturephotonics 153 Harnessing solar energy is one of the most promising ways to tackle today’s energy issues. Although the present dominant photovoltaic (PV) technology is based on inorganic materials, high material and manufacturing costs limit its wide acceptance1. Intensive research has been conducted towards the development of low-cost...
