![]() The microbial photosynthesis generates glucose and oxygen which is consumed by the MFC and generating carbon dioxide and water. The process can be divided into two parts as follows: microbial photosynthesis and MFC. The solar cell reveals a circadian rhythm which is consistent with the photosynthetic nature. have demonstrated a photoelectrochemical solar cell can use marine sediment and seawater to generate electricity from sunlight. The MSCs can be further classified into three major groups on the basis of the photosynthetic organism-phototropic MSCs, plant MSCs, and algae MSCs. MSCs include four basic steps as follows: (1) photosynthesis of organic matter, (2) transfer of organic matter to the anode compartment, (3) EAB oxidizes the organic matter, and (4) oxygen or other electron acceptor's reduction at the cathode. Despite variations in system designs, the basic principle remains the same. Many researchers have reported different related systems with various names. MSC is the group of new biotechnological systems which integrate the microbial electricity or chemical compound generation and the photosynthetic process by the synergistic relationship between EAB and photosynthetic organism. Shantonu Roy, Soumya Pandit, in Microbial Electrochemical Technology, 2019 1.2.6.3 Microbial Solar Cells ![]() Because the solar cells based on nanocrystalline materials are complicated compared with the conventional p–n junction solar cell, the fundamental phenomena are reviewed. It ends with the concepts of solar cell using nanocrystalline materials. This chapter begins with the basic semiconductor physics, which is necessary to understand the operation of p–n junction solar cell, and then describes the basic principles of p–n junction solar cell. The comprehension of the p–n junction solar cell will give you hints to improve solar cells regarding efficiency, manufacturing cost, consuming energy for the fabrication, etc. It is important to learn the basic properties of semiconductor and the principle of conventional p–n junction solar cell to understand not only the conventional solar cell but also the new type of solar cell. A p–n junction is used for charge carrier separation in most cases. The energy conversion consists of absorption of light (photon) energy producing electron–hole pairs in a semiconductor and charge carrier separation. In most cases, semiconductor is used for solar cell material. Solar cell is a key device that converts the light energy into the electrical energy in photovoltaic energy conversion. Tetsuo Soga, in Nanostructured Materials for Solar Energy Conversion, 2006 1. ![]() When photo absorption occurred in silicon, minority carriers (holes) transferred to electrodes along CNTs resulted in an increased solar cell efficiency of 15.2%. The carbon nanotube-embedded graphene was the electrode for charge collection. improved the solar cell efficiency by fabricating graphene–silicon solar cells by adding carbon nanotubes into graphene. ![]() The fabricated solar cells showed a maximum efficiency of 4.03% with AgNW concentration of 0.1 wt% at 3 s of deposition time. fabricated porous silicon heterojunction solar cells by using graphene doped with silver nanowires (AgNWs). To improve the conversion efficiency of solar cells, graphene has been extensively researched to use as counter electrodes, electron donors, or acceptors. The efficiency of solar cells is one of the most important parameters in directly converting light to electricity. Nowadays, solar cell technologies play an import role in electrical power production due to greater power consumption and large population.
