Renewable Energy Lab

Tanzania Project : Potable Water and Solar Energy for the People of Minjingu

Tel Aviv University Branch of Engineers Without Borders

Supported by Boris Mints Institute

The project is supported by BMI, the TAU Renewable Energy Center and the Institute for Water Research.

Project Goals:

• Provide power supply using an off grid photo-voltaic system to Medical Center in the province of Nkaiti.

• Supply clean drinking water to the medical center Nkaiti .

• Supply clean drinking water to one high school in the Nkaiti province.

Our experiment focus on measuring the photon recycling efficiency for characterizing materials and devices for solar energy conversion. we constructed a Photoluminescence quantum yield measuring system and preformed preliminary experiments on an InP sample wafer, producing photoluminescence quantum yield measurement from a sample excited by a range of incident light wavelengths. Over the next year, we plan to calibrate the system and to measure and extract spatial photon recycling efficiency of different materials and various solar devices, while improving the experimental technique.
