Photovoltaic cell flip-chip structure

Introduction to Solar Cells

Solar cells are the electrical devices that directly convert solar energy (sunlight) into electric energy. This conversion is based on the principle of photovoltaic effect in which DC voltage is generated due to flow of electric current between two layers of semiconducting materials (having opposite conductivities) upon exposure to the sunlight [].

Understanding the Composition of a Solar Cell

Figure 4. PV cells are wafers made of crystalline semiconductors covered with a grid of electrically conductive metal traces. Many of the photons reaching a PV cell have energies greater than the amount needed to excite the electrons into a conductive state. The extra energy imparts heat into the crystalline structure of the cell.
