abstract = {Solar photovoltaic (PV) energy generation is highly
dependent on weather conditions and only applicable when the
sun is shining during the daytime, leading to a mismatch
between demand and supply. Merging PVs with battery storage
is the straightforward route to counteract the intermittent
nature of solar generation. Capacity (or energy density),
overall efficiency, and stability at elevated temperatures
are among key battery performance metrics for an integrated
PV–battery system. The performance of high-capacity
silicon (Si)/graphite (Gr) anode and LiNi0.6Mn0.2Co0.2O2
(NMC622) cathode cells at room temperature, 45, and 60 °C
working temperatures for PV modules are explored. The
electrochemical performance of both half and full cells are
tested using a specially formulated electrolyte, 1 M LiPF6
in ethylene carbonate: diethyl carbonate, with 5 wt $\%$
fluoroethylene carbonate, 2 wt $\%$ vinylene carbonate, and
1 wt $\%$ (2-cyanoethyl)triethoxysilane. To demonstrate
solar charging, perovskite solar cells (PSCs) are coupled to
the developed batteries, following the evaluation of each
device. An overall efficiency of $8.74\%$ under standard PV
test conditions is obtained for the PSC charged lithium-ion
battery via the direct-current–direct-current converter,
showing the promising applicability of
silicon/graphite-based anodes in the PV–battery integrated
system.},
