Why do we not have solar panels on every house and car? Because TCO exceeds ROI.In other words, the payback (when productive lifetime is included) is not really enough to justify the investment. What will change this? Increase Efficiency of solar to electric conversion per square meter. Decrease Installed cost per square meter. Increase usable lifetime. Silvija Gradečak and colleagues at MIT have made some progress on the first two. It will be interesting to see how these developments affect the third criteria as organic materials usually degrade at higher rates than silicone.
