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.
The diagram illustrates the conversion of sunlight into electricity via semiconductors, highlighting the key elements: layers of silicon, metal contacts, anti-reflective coating, and the electric field created by the junction between n-type and p-type silicon. The solar cell diagram showcases the working mechanism of a photovoltaic (PV) cell.
These higher energy photons will be absorbed by a silicon solar cell, but the difference in energy between these photons and the silicon band gap is converted into heat (via lattice vibrations — called phonons) rather than into usable electrical energy. The most commonly known solar cell is configured as a large-area p–n junction made from silicon.
The V - I characteristics of the solar cell or the current-voltage (I-V) characteristics of a typical silicon PV cell operating under typical circumstances are displayed in the graph above. The output current and voltage of a single solar cell or solar panel determine how much power it can produce ( I x V ).
The solar cell diagram showcases the working mechanism of a photovoltaic (PV) cell. Sunlight interacts with silicon layers, generating electron-hole pairs. These pairs, driven by the electric field between n-type and p-type silicon, travel to metal contacts, creating a current that is harnessed as electricity.
Single crystal solar cells are often 15.6 × 15.6 cm 2, giving a total current of almost 9 – 10A from a module. The table below shows the output of typical modules at STC. I MP and I SC do not change that much but V MP and V OC scale with the number of cells in the module.

When a photon hits a piece of semiconductor, one of three things can happen: 1. The photon can pass straight through the semiconductor — this (generally) happens for lower energy photons.2. The photon can reflect off the surface.3. The photon can be absorbed by the semiconductor if the photon energy is higher than the band gap value. This generates an electron-hole pair and some…
