Solar photovoltaic technology: A review of different types of solar cells and its future trends

Abstract

The Sun is source of abundant energy. We are getting large amount of energy from the Sun out of which only a small portion is utilized. Sunlight reaching to Earth’s surface has potential to fulfill all our ever increasing energy demands. Solar Photovoltaic technology deals with conversion of incident sunlight energy into electrical energy. Solar cells fabricated from Silicon aie the first generation solar cells. It was studied that more improvement is needed for large absorption of incident sunlight and increase in efficiency of solar cells. Thin film technology and amorphous Silicon solar cells were further developed to meet these conditions. In this review, we have studied a progressive advancement in Solar cell technology from first generation solar cells to Dye sensitized solar cells, Quantum dot solar cells and some recent technologies. This article also discuss about future trends of these different generation solar cell technologies and their scope to establish Solar cell technology.

Towards Self-Powered WSN: The Design of Ultra-Low-Power Wireless Sensor Transmission Unit Based on Indoor Solar Energy Harvester

“…If the photon has sufficient energy to hit the bond of the silicon crystal, an electron pair of positive holes and negative electrons will be generated, as illustrated in Figure 8. This process will cause a voltage difference between the N-channel and the P-channel, which by its role, will drive the electrical current to flow through the depletion layer [25,26].…”

“…will cause a voltage difference between the N-channel and the P-channel, which by its role, will drive the electrical current to flow through the depletion layer [25,26]. Polycrystalline (P-c) and monocrystalline (M-c) solar cells are the most commonly used types of silicon PV [27].…”
