Excitons, bound pairs of electrons and holes, mediate the interconversion of charges and photons and thus can be used for…
Lasing Solar Concentrators are expected to have record efficiency in converting light to electricity. They are basically solar-pumped lasers, which,…
Photovoltaic solar concentrators aim to increase the electrical power obtained from solar cells. Conventional solar concentrators track the sun to…
Figure 1: (a) A schematic representation of a luminescent solar concentrator. The trapping efficiency is defined as the fraction of…
Most modern displays enhance their contrast ratio using combinations of linear polarizers to absorb and dissipate incident light. The polarizers…
The efficiency of solar cells is controlled by the energy gap of the constituent materials. The “single junction limit” is…
