چکیده
This study reports an integrated device of a lithium-ion battery (LIB) connected with Si solar cells. A Li(Ni0.65Co0.15Mn0.20)O2 (NCM) cathode and graphite (G) anode were used to fabricate the (LIB). The surface shape morphologies NCM powder characterized by field emission scanning electron microscopy (FE-SEM). structural properties determined X-ray diffraction (XRD) analysis. XRD patterns powders well matched those JCPDS data. To investigate electrochemical characteristics graphite, cycling tests performed after assembling NCM-Li, G-Li half-cell, NCM-G full-cell. discharge capacity at 0.1C was 189.82 mAh/g−1. NCM-graphite full-cell showed 98.25% cycle retention 1C 50 cycles. obtain enough charging voltage for LIB cells in device, eight single series. short-circuit photocurrent density 4.124 mA/cm2. fill factor open circuit 0.78 4.5 V, respectively. These power conversion efficiency 14.45%. andstorage 7.74%. Charging could be as effective cycler.

Charging Characteristics of Lithium Ion Battery Using Semi-Solar Modules of Polymer:Fullerene Solar Cells
The combination of lithium ion battery (LIB) and organic (polymer) solar cells is expected to deliver versatile self-rechargeable portable energy sources, but less attention has been paid to the charging characteristics of LIB-using polymer solar cells. Here we demonstrate that the LIB packs, which were prepared by using lithium cobalt oxide (LiCoO2) and graphite as a cathode and an anode, resp...
