Efficiency in Solar Cells

The theoretical efficiency limit is calculated with some attention paid to the laws of physics ruling the limiting behavior of the system. Beginning with single gap solar cell systems, moving onward to tandem cells (solar cells containing several p-n junctions), and ending with solar cells with an intermediate energy band gap (created through an impurity in the system) progress towards maximum ...

Modulating Exciton Dynamics in Composite Nanocrystals for Excitonic Solar Cells.

Quantum dots (QDs) represent one of the most promising materials for third-generation solar cells due to their potential to boost the photoconversion efficiency beyond the Shockley-Queisser limit. Composite nanocrystals can challenge the current scenario by combining broad spectral response and tailored energy levels to favor charge extraction and reduce energy and charge recombination. We synt...

Efficiency improvement of crystalline silicon solar cells

To increase the efficiency and reduce the production cost of crystalline silicon (c-Si) solar cells, efforts in the photovoltaic industry are currently put on the process optimization of the cell. Sodium hydroxide/Potassium hydroxide (NaOH/KOH) and isopropyl alcohol (IPA) are widely used in the standard alkaline texturization of mono crystalline silicon (mc-Si) wafers for enhancing the optical ...
