abstract = {The galloping rise in global population in recent years and
the accompanying increase in food and energy demands has
created land use crisis between food and energy production,
and eventual loss of agricultural lands to the more
lucrative photovoltaics (PV) energy production. This
experiment was carried out to investigate the effect of
organic photovoltaics (OPV) and red-foil (RF) transmittance
on growth, yield, photosynthesis and SPAD value of spinach
under greenhouse and field conditions. Three OPV levels (P0:
control; P1: transmittance peak of 0.11 in blue light (BL)
and 0.64 in red light (RL); P2: transmittance peak of 0.09
in BL and 0.11 in RL) and two spinach genotypes (bufflehead,
eland) were combined in a 3 × 2 factorial arrangement
in a completely randomized design with 4 replications in the
greenhouse, while two RF levels (RF0: control; RF1:
transmittance peak of 0.01 in BL and 0.89 in RL) and two
spinach genotypes were combined in a 2 × 2 factorial in
randomized complete block design with four replications in
the field. Data were collected on growth, yield,
photosynthesis and chlorophyll content. Analysis of variance
(ANOVA) showed significant reduction in shoot weight and
total biomass of spinach grown under very low light
intensities as a function of the transmittance properties of
the OPV cell used (P2). P1 competed comparably
(p > 0.05) with control in most growth and yield traits
measured. In addition, shoot to root distribution was higher
in P1 than control. RF reduced shoot and total biomass
production of spinach in the field due to its inability to
transmit other spectra of light. OPV-RF transmittance did
not affect plant height (PH), leaf number (LN), and SPAD
value but leaf area (LA) was highest in P2. Photochemical
energy conversion was higher in P1, P2 and RF1 in contrast
to control due to lower levels of non-photochemical energy
losses through the Y(NO) and Y(NPQ) pathways.
Photo-irradiance curves showed that plants grown under
reduced light (P2) did not efficiently manage excess light
when exposed to high light intensities. Bufflehead genotype
showed superior growth and yield traits than eland across
OPV and RF levels. It is therefore recommended that OPV
cells with transmittance properties greater than or equal to
$11\%$ in BL and $64\%$ in RL be used in APV systems for
improved photochemical and land use efficiency.},
