Optimization of Photosynthetic Photon Flux Density and Light Quality for Increasing Radiation-Use Efficiency in Dwarf Tomato under LED Light at the Vegetative Growth Stage

Plants, 2021
Dwarf tomatoes are advantageous when cultivated in a plant factory with artificial light because they can grow well in a small volume. However, few studies have been reported on cultivation in a controlled environment for improving productivity.

Optimizing Planting Density for Increased Resource Use Efficiency in Baby-Leaf Production of Lettuce (Lactuca sativa L.) and Basil (Ocimum basilicum L.) in Vertical Farms

Horticulturae
Vertical farming is gaining popularity as a sustainable solution to global food demand, particularly in urban areas where space is limited. However, optimizing key factors such as planting density remains a critical issue, as it directly affects light ...

Simulation of Gross Primary Productivity Using Multiple Light Use Efficiency Models

Land, 2021
Gross primary productivity (GPP) is the most basic variable in a carbon cycle study that determines the carbon that enters the ecosystem. The remote sensing-based light use efficiency (LUE) model is one of the primary tools that is currently used to ...

Efficient light harvesting using simple porphyrin-oxide perovskite system [PDF]

Scientific Reports, 2020
AbstractHere, we report the systematic studies on photoanodes of phase pure polycrystalline microrods of Barium Stannate (BaSnO3) microrods for application in porphyrin dye-sensitized solar cell (DSSC). We were able to establish the effect of vacuum annealing on BaSnO3 thin films on its electrical, optical and adsorption properties using XPS, UV–Vis ...

Comparison of the device physics principles of planar and radial p-n junction nanorod solar cells [PDF]

, 2005
A device physics model has been developed for radial p-n junction nanorod solar cells, in which densely packed nanorods, each having a p-n junction in the radial direction, are oriented with the rod axis parallel to the incident light direction.

Modeling the Effects of Global and Diffuse Radiation on Terrestrial Gross Primary Productivity in China Based on a Two-Leaf Light Use Efficiency Model

Remote Sensing, 2020
Solar radiation significantly affects terrestrial gross primary productivity (GPP). However, the relationship between GPP and solar radiation is nonlinear because it is affected by diffuse radiation.

Estimation of Leaf Area and Light-use Efficiency by Non-destructive Measurements for Growth Modeling and Recommended Leaf Area Index in Greenhouse Tomatoes

The Horticulture Journal, 2020
We aimed to monitor greenhouse tomato growth without destructive sampling and investigated an empirical growth model in which dry matter production was obtained as a product of light intercepted by plants and light-use efficiency.

Efficient light propagation algorithm using quantum computers

Physica Scripta
Abstract Quantum algorithms can potentially overcome the boundary of computationally hard problems. One of the cornerstones in modern optics is the beam propagation algorithm, facilitating the calculation of how waves with a particular dispersion relation propagate in time and space. This algorithm solves the wave propagation equation by
