Have you ever heard of an open source solar cell?
Windorah is the first project of its kind, and you are invited. Do you trust a solar cell if its made from across the world? Do you know how it works, and can you fix it if it breaks? If your answer is no, you feel the same way I do.
Short introduction about me: Born and raised with the attitude that "if you chop your own wood, it will warm you twice"! Studied a bunch of stuff, but hey, the only thing that matters is what you do with what you've learned.
This campaign aims at finishing a home build solar cell and testing it. The goals are overwhelming: 20 % efficiency under normal sunlight and 30 % efficiency under concentrated sunlight, but more importantly, IT CAN BE MADE OR FIXED IN A WORKSHOP.... (gasp)!!!
The aims are high, but the challenges are numerous and there are various ways for you to contribute.
What We Need & What You Get
Actually very little is needed:
2000$ cover a CdTe solar cell and a-Si solar cell (+ transport and VAT), an arduino microcontroller, resistors, wires and expenses related to testing the finalized module under standard conditions. If the goal is reached, you get amazing schwag (see below). If the goal of 2000$ is not reached in 30 days, no credit cards will be charged.
High efficiency solar cells were not intuitive until now. This is an invitation to everyone who prefers local energy over centralized power plants, and prefer "break it - fix it" over "buy it - trash it". Imagine if a simple solar cell design is shared on the internet by the time we run out of resources. Whoaah.... this is great!!
Other Ways You Can Help
With an intuitive design comes the possibility for much more people to contribute.
For instance, if you live in a village in Asia, you work with bamboo, and you know just how to make a structure out of it, perhaps you can build a rigid frame to support 10m2 of plastic mirror.
If you are a scientist in Brazil who can make a solar cell converting blue light, well hey, there is room for your solar cell here man. We can just extend the box 1 foot / 30 cm, add in one extra filter and BANG, there we go.
If you are a native Chinese speaker, able to research your way through the jungle of Chinese websites, perhaps you can track down a Chinese supplier of these filters. They are called Dielectric Interference Filters, and I'm gonna put their specifications out on the internet for all of you.
