Being the most used PV technology, Single-crystalline silicon (sc-Si) solar cells normally have a high laboratory efficiency from 25% to 27%, a commercial efficiency from 16% to 22%, and a bandgap from 1.11 to 1.15 eV [4,49,50].
Crystalline silicon and GaAs solar cells continue to be one of the most promising PV technologies due to their low fabrication and material costs of the first and high performance of the second one. GaAs solar cells are highly efficient devices but much too expensive for terrestrial large-area applications.
Air and water cooled ‘hybrid’ photovoltaic–thermal solar collectors are reported. These include prospective applications of amorphous silicon solar module on flexible plastic film and thin film solar cells. Topics include general results and analysis of the heat transfer mechanisms of the PV modules. 1. Introduction
The emissivity of the non-encapsulated c-Si solar cell was determined to be 75% in the MIR range, and the emission of free charge carriers dominates in the highly doped emitter and back surface layers of the array. Both effects are enhanced by the improved optical connectivity resulting from the texture of the front surface.
Front and Back Contact Formation Technically, a silicon wafer is a solar cell when the p–n junction is formed, but it only becomes functional after metallisation. The metal contacts play a key role in the production of highly efficient and cost-effective crystalline Si PV cells.
The device structure of a silicon solar cell is based on the concept of a p-n junction, for which dopant atoms such as phosphorus and boron are introduced into intrinsic silicon for preparing n- or p-type silicon, respectively. A simplified schematic cross-section of a commercial mono-crystalline silicon solar cell is shown in Fig. 2.
