Science-Accepted “Super Low Cost”
Solar 8 Infrared/BEC
• —>> con'nued: ■1. Excess S-Q SJ Solar cell :
vii Heavier on theory: Fill factor(FF, Available power at the maximum point)
modelling shows higher limit for Organic Solar Cell(VA Trukhanov+),
Nanostructured cell limit doesn’t apply(Yunlu Xu+), Combine Upconversion &
MEG(Shpaisman+), ApplicaOon of Photonic Bose-Einstein condensates(BEC) to
concentrate, amplify, store light etc. Some algae-bacteria’s photon-to-charge
conversion raOo is close to 100%(FH Alharbi+), Solar cell SuperAbsorpOon of
light(KDB Higgins+), But S-Q limit seems to come from non-empirical data(& new
data aZer 1960s excluded) & mostly based on 2nd law of thermo-dynamics'
theoreOcal discourse without substanOal data back up(Bolin Liao+), which has
(ignored) contradicOons (p194-196) and considered as more of condiOonal
reference by many even in mainstream level, at least privately.
• ■2. Under S-Q limit? Photovoltaic Solar Cell: but sOll significant cost reducOon
methods, commercialized or prototype lowest cost products, some redundant:
i 25% field efficiency SJ silicon cell(Solvoltaics+), ii OpOcal RecOficaOon non-
semiconductor cell(Ste Rand+), iii Consolidated solar cell(M Baldo),
iv Low cost thin film/organic solar cell by light trapping: classical limit 15x
exceeding nanophotonic type: by resonance for full absorpOon (Shanhui Fan+), or
by Fullerene C60(Sunpower C60)/Coherent PopulaOon Trapping(CPT),
