Learning how to read a learning curve
Market analysis: The last edition of the International Technology Roadmap for Photovoltaic (ITRPV) roadmap addressed the end of the learning curve for PV modules as we know it. What lies behind the end of the learning curve is also the end of a common belief: industries cannot always be compared and PV is no exception to a common Shaddock-style rule: “if you believe you know what is going to happen, then you did something wrong”, argues Becquerel Institute co-founder and director Gaëtan Masson.
