Silicon solar cells produced by a usual technology in p-type, crystalline silicon wafer were investigated. The manufactured solar cells were of total thickness 450 mm, the junction depth was of 0.5 mm – 0.7 mm. Porous silicon technologies were adapted to enhance cell efficiency. The production of porous silicon layer was carried out in HF: ethanol = 1 : 2 volume ratio electrolytes, illuminating by 50 W halogen lamps at the time of processing. The etching current was computer-controlled in the…

Enhancement of Solar Cell Performance Based On Porous Silicon
Recently, nanometer size semiconductors have been a topic of great interest. Chemical etching of silicon produce P-Si layers have a strong link between the details of processing and the optical and


Porous silicon applications in solar cell technology
Two different applications of PS layers in the solar cell technology were demonstrated. In the first case, microporous layers, which are formed on silicon surface after relatively long anodical
High-efficiency silicon solar cells
Silicon solar cells are described which operate at energy conversion efficiencies independently measured at 18.7 percent under standard terrestrial test conditions (AM1.5, 100 mW/cm2, 28°C). These
Chirped porous silicon reflectors for thin-film epitaxial silicon solar cells
The studies of porous silicon as a one-dimensional photonic crystal have led to solutions allowing the fabrication of broad photonic band gaps as large as several hundreds nanometers for various
Low-cost industrial technologies of crystalline silicon solar cells
Approximately 2 billion people, mainly in Third World countries, are not connected to an electric grid. The standard, centralized grid development is too expensive and time consuming to solve the
