Tracking solar cell conversion efficiency
Nature Reviews Physics, 2020Keeping track of the rapidly improving solar cell performance is not as easy as it might seem. Martin Green describes the Solar Cell Efficiency Tables that have been providing 6-monthly updates of record solar cell performance since the 1990s. Keeping track of the rapidly improving solar cell performance is not as easy as it seems.

Wind Energy Conversion Efficiency Limit
Wind Engineering, 2006The momentum analysis of Sharpe [3] is considered further. It is shown that the maximum wind energy conversion efficiency limit, or the Betz limit of 59.3%, deduced from conventional actuator disc theory is the limiting stationary maximum value as wind turbine rotor speed approaches infinity and rotor outlet swirl approaches zero.

Solar-to-Biomass Conversion Efficiency
2015A maximum theoretical yield in solar-to-biomass conversion can be estimated from the efficiency of the photosynthetic process, considering utilization of all available light. The solar-to-biomass conversion yield is expected to be higher in algae than in terrestrial plants, because algae do not need to consume energy for the development of supporting ...

Efficient Circuit to CNF Conversion
2007Modern SAT solvers are proficient at solving Boolean satisfiability problems in Conjunctive Normal Form (CNF). However, these problems mostly arise from general Boolean circuits that are then translated to CNF. We outline a simple and expressive data structure for describing arbitrary circuits, as well as an algorithm for converting circuits to CNF ...

Light Conversion Efficiency in Photosynthesis
1977The process of photosynthesis involves the conversion of light energy into chemical energy. Electromagnetic radiation is emitted and absorbed in discrete quantities (quanta) of radiant energy called photons possessing an energy E=hv, where h is Planck’s constant and v the frequency of the radiation.

80% Nonlinear Conversion Efficiency: When?
Compact Blue-Green Lasers, 1992Improvements in the efficiency of cw second harmonic generation (SHG) and cw optical parametric oscillation depend on the ratio of the nonlinearity to the loss in the nonlinear medium. External resonant SHG in monolithic lithium niobate crystals has now reached 69% conversion efficiency.
