Abstract
(EN)
The present invention provides a solar energy generating electricity device with doubling light comprising a collecting electricity device and one or more energy concentrating unit, each of the said energy concentrating units includes: a photovoltaic cell plate directly exposed to the sun's rays, and two plane reflectors being symmetrically diposed on the both sides of photovoltaic cell plate and inclined towards the sun the projection length of the said reflector in width direction of photovoltaic cell plate is 0.8-1.5 times of the width of the photovoltaic cell plate; the inclination angle between the plane reflector and the photovoltaic cell plate is 95º-115º the said collecting electricity device connects the solar cells with each other in series and/or in parallel. The doubling light structure of energy concentrating unit in the solar energy generating electricity device with doubling light causes temperature rise of the photovoltaic cell plate lower while obtaining enough illumination. Thus retarding ageing phenomenon of the photovoltaic cell plate, saving lots of maintenance charge, and promoting extremely wide application of solar energy generating electricity.

La présente invention concerne un dispositif d’énergie solaire produisant de l’électricité avec lumière de doublage comprenant un dispositif électrique collecteur et une ou plusieurs unités de concentration d’énergie, chacune desdites unités de concentration d’énergie comprenant : une plaque à cellule photovoltaïque directement exposée aux rayons du soleil, et deux réflecteurs plans étant disposés de manière symétrique des deux côtés de la plaque à cellule photovoltaïque et inclinés vers le soleil, la longueur de projection desdits réflecteurs dans le sens de la largeur de la plaque à cellule photovoltaïque correspondant à 0,8-1,5 fois la largeur de la plaque à cellule photovoltaïque ; l’angle d’inclinaison entre le réflecteur plan et la plaque à cellule photovoltaïque étant de 95°-115°, ledit dispositif électrique collecteur connectant les cellules solaires les unes aux autres en série et/ou en parallèle. La structure de lumière de doublage de l’unité de concentration d’énergie dans le dispositif d’énergie solaire produisant de l’électricité avec lumière de doublage provoque une hausse réduite de température de la plaque à cellule photovoltaïque tout en obtenant un éclairage suffisant. Le dispositif selon l’invention permet par conséquent de retarder le phénomène de vieillissement de la plaque à cellule photovoltaïque, d’économiser de nombreux frais de maintenance, et de promouvoir une application extrêmement large de l’énergie solaire productrice d’électricité.
