2014/12/1
WEST LAFAYETTE, Ind. – An emerging class of electrically conductive plastics called "radical polymers” may bring low-cost, transparent solar cells, flexible and lightweight batteries, and ultrathin an...
Some energy scientists have ambitions as astronomical engineers. Their goal is to convert solar energy into electricity by primarily tailoring the solar irradiation rather than optimizing the photovol...
Detailed Balance Analysis and Enhancement of Open-Circuit Voltage in Single-Nanowire Solar Cells
Nanowire solar cell detailed balance open-circuit voltage effi ciency limit coherent eff ect resonance
2015/8/6
We present a detailed balance analysis of current density−voltage modeling of a single-nanowire solar cell. Our analysis takes into account intrinsic material nonidealities in order to determine...
Standard solar cells heat up under sunlight. The resulting increased temperature of the solar cell has adverse consequences on both its efficiency and its reliability. We introduce a general approach ...
