@BrunoBertez Sans compter les IA chinoises, quasi gratuites ou carrément open source. Les boites comme OpenAI, Anthropic n'ont strictement aucun moat. Je suis très étonné qu'elles ne se soient pas crashées quand DeepSeek est sorti...
@thechosenberg The market wil never go down in a currency that falling accordingly. Basicly the floor goes down so the stock market never touch the ground.
A Chinese research team has recently achieved a breakthrough in the performance of a new thin-film photovoltaic technology, raising the certified efficiency of CZTSSe cells to 16.6%, marking a critical step toward industrialization.
Composed of common elements such as copper, zinc and tin, the CZTSSe photovoltaic offers advantages including abundant resources, low cost, environmental friendliness, and resistance to space radiation.
The team developed an atomic vacancy strategy to guide the orderly positioning of copper and zinc atoms, fundamentally reducing defect activity and internal energy losses. Based on the progress, the team also developed the high-performance flexible cells and modules.
Once cell efficiency approaches 20% and module efficiency reaches 18%, enabling mass production, the technology will become market-competitive and is expected to be widely applied in aerospace equipment and other scenarios.
