چکیده

We present a pure photonic approach to overcome the Shockley-Queisser limit. A single material can show different effective bandgap, set by its absorption spectrum, which depends on its photonic structure. In a tandem cell configuration constructed from a single material, one can achieve two different effective bandgaps, thereby exceeding the Shockley-Queisser limit.

Third generation photovoltaics

We review recent progress towards increasing solar cell efficiencies beyond the Shockley-Queisser efficiency limit. Four main approaches are highlighted: multi-junction cells, intermediate-band cells, hot carrier cells and spectrum conversion. Multi-junction cells use multiple solar cells that selectively absorb different regions of the solar spectrum. Intermediateband cells use one junction wi...

IR light harvesting with silicon microspheres - application to photovoltaic devices

Single-junction photovoltaic devices suffer from intrinsic obstacles limiting their efficiency to a top value dictated by the well-known Shockley–Queisser (SQ) limit [1]. The most fundamental limitation is given by the energy bandgap of the semiconductor, which determines the minimum energy of photons that can be converted into electron-hole pairs. In the case of silicon a large percentage of i...

The effect of photonic bandgap materials on the Shockley-Queisser limit

The limiting efficiency of photovoltaic energy conversion was determined by Shockley and Queisser using the theory of detailed balance, which described the balance between absorption and emission of photons. However, when a material is placed on top of a solar cell that modifies the transmission of photons (e.g., a photonic crystal), both the absorption and emission of photons are modified. Her...

Solar Rectennas - Nanosized Rectenna for Solar Cells

Current solar cell technology is based in the photovoltaic effect occurring in semiconductor materials. It is well-known that the conversion efficiency of these types of solar cells is theoretically limited as first noted by Shockley and Queisser (S&Q): a crystalline silicon device is limited to a conversion efficiency of 33.7 %. The theoretical limit of an infinite multi-junction cell is 86 %....

Exceeding the solar cell Shockley–Queisser limit via thermal up-conversion of low-energy photons

Maximum efficiency of ideal single-junction photovoltaic (PV) cells is limited to 33% (for one sun illumination) by intrinsic losses such as band edge thermalization, radiative recombination, and inability to absorb below-bandgap photons. This intrinsic thermodynamic limit, named after Shockley and Queisser (S-Q), can be exceeded by utilizing low-energy photons either via their electronic up-co...
