IDEA #263LFW Solar Arrays For Portable Electronic Equipment: Production Technology

SOLAR ARRAYS FOR PORTABLE ELECTRONIC EQUIPMENT :: PRODUCTION TECHNOLOGY APPLIED RESEARCH • SOLARTECHNOLOGY AND PHOTOELECTRICS Description The increased number of complicated portable electronic equipment containing electrical accumulator batterys in last 5(cid:2)10 years, tendency to widening of the equipment functions and reduction of dimensions, and also pressing need for mass application of ecologically pure renewable sources of energy – these are the necessary prerequisites for mass application of decentralized photovoltaic chargers. Portable solar arrays are intended for professional and every(cid:2) day portable electronic equipment power supply (mobile and satellite phones, satellite navigation systems, portable com(cid:2) puters, modern photo(cid:2) and video(cid:2) cameras, ecological moni(cid:2) toring equipment, audio equipment etc.) in autonomous con(cid:2) ditions. The principle of electrical energy generation by solar arrays is based on photovoltaic effect in semiconductor structures with p(cid:2)n(cid:2) junction. The monocrystalline silicon as material for solar cells is used. It allows to ensure high efficiency of photocon(cid:2) version and long service life. The hermetic sealing is carried out with the use of hot lamination in vacuum technology. On Fig. 1 a vacuum laminator VL540/290 is presented which was developed and made in SDTB of V.Lashkaryov ISP of NAS of Ukraine and was used for experimental samples of solar arrays manufacturing.. On Fig. 2 an experimental sample of solar array for mobile phones SBMT(cid:2)S(cid:2)8.0(cid:2)0.23 is presented, which can be used for other portable equipment as well..
