Title: Photovoltaic device
Inventor: OKADA NAOTO
IPC: H01L31/04
Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To enhance a photovoltaic device in operating voltage using a current collecting electrode of low cost without increasing a shadow loss, by a method wherein the photovoltaic device is possessed of two current collecting electrodes which are different from each other in resistance per unit length, and the characteristics of the current collecting electrodes with an intersection are set position-dependent in the direction of the current collecting electrode smaller in resistance per unit length than the other. SOLUTION: A photovoltaic device 101 is possessed of grid current collecting electrode 103 which are each high in resistance per unit length and a bus bar current collecting electrode 104 which is low in resistance per unit length. A lot of grid electrodes 103 are arranged on the plane of a photoelectric conversion part 102 so as to collect carriers generated at points on the photoelectric conversion part 102 through the intermediary of a transparent electrode. Therefore, the grid current collecting electrodes 103 are formed thin as far as resistance permits so as not to screen a semiconductor layer from incident light. Carriers generated in the photovoltaic device 101 are outputted through the grid electrodes 103 and the bus bar electrode 104. Therefore, no voltage drop occurs in the bus bar electrode 104, and all points have an equipotential.

IPC: H01L31/04
Filed: 1981-03-20
Abstract: PURPOSE:To increase the power generating effect of the titled solar battery by a method wherein a latent heat accumulating material is applied on the rear surface of the battery to thereby prevent the overheating of the battery. CONSTITUTION:The latent heat accumulating material 3 is put into a container made of a material of good heat conductivity and the container is applied onto the rear surface of the solar battery 1. In this case, when the rear surface of the solar battery is subjected to sunlight, a part of the sunlight reflects upon the surface and a part of the reflected sunlight is converted partly into electrical energy and partly into heat energy to thereby elevate the temperature of the solar battery 1. Further, the heat energy thus obtained is stored in the latent heat accumulating material 3 applied on the rear surface of the solar battery and after the time when the temperature of the material 3 reaches its shifting point, the material 3 keeps its temperature constant. Consequently, the solar battery 1 is not overheated and accordingly, the power generating efficiency of the solar battery is not reduced.
