If the cell is getting warm/hot during charge above 4.15, then it''s either a bad cell, or just needs to be cycled a few times like jdeadman said. However, like Sean mentions, not all cells are "designed" for 4.2V. Just most are. So you should definitely check the datasheets to compare to make sure your cells are in fact 4.2V fully charged.

The history of CIGS began in the early 1950s when the ternary compound CuInSe 2 was first synthesized and semiconducting properties were identified by Hahn et al. [].At that time, photovoltaics was still limited to Se-based photodetector applications until the first Si- and CdS-based solar cells reached notable conversion efficiencies in the mid-1950s.

Photovoltaic (PV) cells, commonly known as solar cells, are the building blocks of solar panels that convert sunlight directly into electricity. Understanding the construction and working principles of PV cells is essential for appreciating how solar energy systems harness renewable energy.
Understanding the construction and working principles of PV cells is crucial for appreciating how solar energy is harnessed to generate electricity. The photovoltaic effect, driven by the interaction of sunlight with semiconductor materials, enables the conversion of light into electrical energy.
Solar Cell Definition: A solar cell (also known as a photovoltaic cell) is an electrical device that transforms light energy directly into electrical energy using the photovoltaic effect.
1. Basic Structure A typical PV cell is composed of several layers of materials, each serving a specific function to capture and convert sunlight into electrical energy. The main components include: Semiconductor Material: Usually silicon, which can be either monocrystalline, polycrystalline, or amorphous.
A solar cell (also known as a photovoltaic cell or PV cell) is defined as an electrical device that converts light energy into electrical energy through the photovoltaic effect. A solar cell is basically a p-n junction diode.
The common single junction silicon solar cell can produce a maximum open-circuit voltage of approximately 0.5 to 0.6 volts. By itself this isn't much – but remember these solar cells are tiny. When combined into a large solar panel, considerable amounts of renewable energy can be generated.
