Unlike the iPhone 11 Pro and iPhone 11 Pro Max where the only difference was the screen size and battery capacity, the iPhone 12 Pro Max adds a 47% larger sensor and sensor-shift image stabilization to the main camera lens, and replaces the f/2.0 aperture 52 mm telephoto camera lens with a f/2.2 aperture 65 mm lens, allowing for a 2.5x optical ...
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
Capacity utilization or capacity utilisation is the extent to which a firm or nation employs its installed productive capacity (maximum output of a firm or nation). It is the relationship between output that is produced with the installed equipment, and the potential output which could be produced with it, if capacity was fully used. [1]
Thermodynamic efficiency limit is the absolute maximum theoretically possible conversion efficiency of sunlight to electricity. Its value is about 86%, which is the Chambadal-Novikov efficiency , an approximation related to the Carnot limit , based on the temperature of the photons emitted by the Sun's surface.

The maximum value of f without light concentration (with reflectors for example) is just f ω /2, or 1.09 × 10 −5, according to the authors. Using the above-mentioned values of Q s and Q c, this gives a ratio of open-circuit voltage to thermal voltage of 32.4 (V oc equal to 77% of the band gap). The authors derive the equation
