Ontario Tech acknowledges the lands and people of the Mississaugas of Scugog Island First Nation.

We are thankful to be welcome on these lands in friendship. The lands we are situated on are covered by the Williams Treaties and are the traditional territory of the Mississaugas, a branch of the greater Anishinaabeg Nation, including Algonquin, Ojibway, Odawa and Pottawatomi. These lands remain home to many Indigenous nations and peoples.

We acknowledge this land out of respect for the Indigenous nations who have cared for Turtle Island, also called North America, from before the arrival of settler peoples until this day. Most importantly, we acknowledge that the history of these lands has been tainted by poor treatment and a lack of friendship with the First Nations who call them home.

This history is something we are all affected by because we are all treaty people in Canada. We all have a shared history to reflect on, and each of us is affected by this history in different ways. Our past defines our present, but if we move forward as friends and allies, then it does not have to define our future.

Title: Towards the Lambertian Limit in Thin Films Silicon Solar Cells

Abstract: Trapping of solar light into active semiconductor materials is gaining large interest in order to find a way to increase absorption in thin film solar cells, while keeping reasonable conversion efficiency and reducing the manufacturing costs. In this seminar I will present a theoretical study of light trapping in thin film crystalline silicon solar cells with ordered and disordered photonic structures. The general aspects of these two complementary optical designs are discussed, focusing on the absorption in the active material and on the resulting photo generated current, which are assumed as the figures of merit. We will show that the optimal photonic configuration from the point of view of light trapping is neither perfectly ordered nor totally random and that an engineered combination of both order and disorder is able to approach the ideal Lambertian light trapping.
