Solar Cell

      1 Comment on Solar Cell

Solar cell, also known photovoltaic cell, any device that directly converts the energy of light into electrical energy through the photovoltaic effect. The  majority of solar cells are fabricated from silicon—with increasing efficiency and lowering cost as the materials range from amorphous (non-crystalline) to polycrystalline to crystalline (single crystal) silicon forms. Unlike batteries or fuel cells, solar cells do not utilize chemical reactions or require fuel to produce electric power, and, unlike electric generators, they do not have any moving parts.

In many such cells, the absorber layer and the back junction layer are both made of the same material. Solar cells can be arranged into large groupings called arrays. These arrays, composed of many thousands of individual cells, can function as central electric power stations, converting sunlight into electrical energy for distribution to industrial, commercial, and residential users. Solar cells in much smaller configurations, commonly referred to as solar cell panels or simply solar panels, have been installed by homeowners on their rooftops to replace or augment their conventional electric supply.

Solar cell panels also are used to provide electric power in many remote terrestrial locations where conventional electric power sources are either unavailable or prohibitively expensive to install. Because they have no moving parts that could need maintenance or fuels that would require replenishment, solar cells provide power for most space installations, from communications and weather satellites to space stations. (Solar power is insufficient for space probes sent to the outer planets of the solar system or into interstellar space, however, because of the diffusion of radiant energy with distance from the Sun.) Solar cells have also been used in consumer products, such as electronic toys, handheld calculators, and portable radios. Solar cells used in devices of this kind may utilize artificial light (e.g., from incandescent and fluorescent lamps) as well as sunlight.

About Md. Shafiul Islam

I have been working as an Assistant Professor since May 26, 2015.My research profile lies at the interface of biomaterial science, life sciences and engineering. I am particularly interested in the design of bionanocomposite materials for relevant clinical applications, e.g. in the context of fabricating and testing biocomposite materials to study the biocompatibility with human body to repair bone tissue. I joined as a lecturer at Noakahli Science and Technology University in May 26,2013. During my working as a Lecturer, I did research on waste water treatment. In connection to this, I applied nanotechnology to treat water as well as waste water. Prior to joining the Noakhali Science and Technology University , I joined as a Scientific Officer in Drug & Toxins Lab as well as Polymer Chemistry Lab at Bangladesh Council of Scientific & Industrial Research (BCSIR).Before doing scientific works, I did M.S. thesis work in the Institute of Polymer & Radiation Technology. I completed my undergraduate studies in Applied Chemistry & Chemical Engineering ( University of Dhaka, Bangladesh) and gained my M.S. in the same department, under the supervision of Professor Dr. Mohammed Mizanur Rahman (University of Dhaka, Bangladesh), where he investigated the effect of reinforcement of nano-materials into bio-polymer composite, morphology and the effect of bacteria in the bio-composite. . I achieved Dean's Award in recognition of my excellent academic and oerall performance in B.Sc. In Bangladesh,I was shortlisted for National Science & Technology (NST) Fellowship and was successful in securing funding from Ministry of Science & Technology, in collaboration with Professor Dr.Mohammed Mizanur Rahman, University of Dhaka, towards the manufacture of medical devices that are resistant to microbial colonization. I have authored 6 research papers and 1 conference paper (h-index: 2).
