Summary: Polysilicon, a highly refined form of silicon, is the starting material for solar cells. For silicon-based solar cells, polysilicon is the starting material. What is polysilicon, and how is a silicon cell made from polysilicon? Polysilicon is formed from Quartzite,…
Battery Storage – Making Solar Power Stable
Summary: How can you use solar power when there is no sunlight? By storing the power generated during sunshine hours in batteries. Does solar power need battery storage? If yes, under what circumstances? What types of batteries are used for solar power…
Silicon Wafer – The Chip that is Healthy and Gives You Power
Summary: Silicon cells are made from silicon wafers. Silicon wafers are in turn formed from polysilicon ingots. You surely would have heard about solar cells. But did you know that the crystalline solar cells come from silicon wafers? Yes, wafers.…
Concentrating Photovoltaics – Getting More Power from the Same Area
Summary: Concentrating PV technology concentrates more sunlight onto a unit area of solar cells, resulting in much higher efficiency of sunlight conversion to electricity. An interesting way to significantly increase the efficiency of solar cells is to concentrate the light that…
